3. Product Description

Use

The vacuum pump is intended for the suction of air and other dry, non-aggressive, non-toxic and non-explosive Gases.

Conveying media with a lower or higher density than air leads to an increased thermal and/or mechanical load on the vacuum pump and is permissible only after prior consultation with Schmalz.

Permissible temperature range of the inlet gas: see “Oil”, “Ambient temperature range”

In case the vacuum pump is equipped with a gas ballast (optional) water vapour within the gas flow can be tolerated within certain limits ( page 9: Conveying Condensable Vapours). The conveyance of other vapours shall be agreed upon with Schmalz.

The vacuum pump is intended for the placement in a nonpotentially explosive environment.

Version with float valve (j, 200) and oil return line:

The vacuum pump is thermally suitable for continuous operation (100 percent duty).

Version with oil return valve (f, 280):

The vacuum pump is thermally suitable for continuous operation (observe the notes with regard to the oil recirculation:  page 4: Oil Circulation;  page 9: Oil Return).

The vacuum pump is ultimate pressure proof.

Principle of Operation

The vacuum pump works on the rotating vane principle.

A circular rotor (s, 14) is positioned centrically on the shaft of the vacuum pump. The shaft of the vacuum pump is driven by the drive motor shaft by means of a flexible coupling (310).

The rotor (s, 14) rotates in an also circular, fixed cylinder (t, 1), the centreline of which is offset from the centreline of the rotor such that the rotor and the inner wall of the cylinder almost touch along a line. Vanes (r, 22), sliding in slots in the rotor, separate the space between the rotor and the cylinder into chambers. At any time gas is sucked in and at almost any time ejected. Therefore the vacuum pump works almost pulsation free.

In order to avoid the suction of solids, the vacuum pump is equipped with a screen (261) in the suction connection. In order to avoid reverse rotation after switching off, the vacuum pump is equipped with a non-return valve (257).

Note: This valve shall not be used as a non-return valve or shut-

off valve to the vacuum system and is no reliable means to prevent suction of oil into the vacuum system while the vacuum pump is shut down.

In case the vacuum pump is equipped with a gas ballast (optional):

Through the gas ballast (440) a small amount of ambient air is sucked into the pump chamber and compressed together with the process gas. This counteracts the accumulation of condensates from the process gas inside the vacuum pump ( page 9: Conveying Condensable Vapours).

The gas ballast line is equipped with a sinter metal filter.

Gas ballast version with ball valve:

The gas ballast line can be closed partially or completely by means of a ball valve.

In order to improve the operating characteristics the outlet of the pump chamber is equipped with a spring loaded valve (q, 159).

Oil Circulation

The vacuum pump requires oil to seal the gaps, to lubricate the vanes (r, 22) and to carry away compression heat.

The oil reservoir is located on the pressure side of the vacuum pump (i.e. high pressure) at the bottom of the bottom chamber of the oil separator (o, 75).

The feed openings are located on the suction side of the vacuum pump (i.e. low pressure).

Forced by the pressure difference between pressure side and suction side oil is being drawn from the oil separator (o, 75) through the oil supply lines (210) and injected on the suction side.

Together with the sucked gas the injected oil gets conveyed through the vacuum pump and ejected into the oil separator (o,

75) as oil mist. Oil that separates before the exhaust filter (p, 120) accumulates at the bottom of the bottom chamber of the oil separator (o, 75).

Oil that is separated by the exhaust filter (p, 120) accumulates at the bottom of the upper chamber of the oil separator (o, 75).

The flow resistance of the exhaust filters (p, 120) causes the inside of the exhaust filters (which is connected to the bottom chamber of the oil separator) to be on a higher pressure level than the outside of the exhaust filters (i.e. the upper chamber of the oil separator). Because of the higher pressure in the bottom chamber it is not possible to let oil that drips off the exhaust filters simply flow down to the bottom chamber.

Version with float valve and oil return line to the suction connection (j, 200):

Therefore the oil that accumulates in the upper chamber is sucked through the float valve (j, 200) and the oil return line (j,

195) to the suction connection (250).

Version with oil return valve (f, 280):

At continuous operation this would cause the entire supply of oil to accumulate at the bottom of the upper chamber, expel oil droplets through the gas discharge/pressure connection and let the vacuum pump run dry. Therefore the vacuum pump must be shut down at the latest after 10 hours of continuous operation, depending on the operating conditions even after a shorter period, for at least approx. 15 minutes ( page 8: Operation Notes). After turning off the vacuum pump the pressure difference between the inside and the outside of the exhaust filter(s) (p, 120) collapses, hence the two chambers of the oil separator assume an equal pressure level, the oil return valve (f, 280) between the two chambers opens and the accumulated oil in the upper chamber can run down to the bottom chamber.

Cooling

The vacuum pump is cooled by – radiation of heat from the surface of the vacuum pump incl.

oil separator (o, 75)

– the air flow from the fan wheel of the drive motor (400) – the process gas – the air flow from the fan wheel (e, 321) on the shaft of the

vacuum pump

Start Controls

The vacuum pump comes without start controls. The control of the vacuum pump is to be provided in the course of installation.

4. Safety

Intended Use

Definition: For the purpose of these instructions, “handling” the

vacuum pump means the transport, storage, installation, commissioning, influence on operating conditions, maintenance, troubleshooting and overhaul of the vacuum pump. The vacuum pump is intended for industrial use. It shall be handled only by qualified personnel.

The allowed media and operational limits ( page 3: Product Description) and the installation prerequisites ( page 6: Installation Prerequisites) of the vacuum pump shall be observed both by the manufacturer of the machinery into which the vacuum pump is to be incorporated and by the operator.

The maintenance instructions shall be observed. Prior to handling the vacuum pump these installation and operating instructions shall be read and understood. If anything remains to be clarified please contact your Schmalz representative!

Safety Notes

The vacuum pump has been designed and manufactured according to state-of-the-art methods. Nevertheless, residual risks may remain. These operating instructions highlight potential hazards where appropriate. Safety notes are tagged with one of the keywords

DANGER, WARNING and CAUTION as follows:

Emission of Oil Mist

The oil in the process gas is separated to the greatest possible extent, but not perfectly.

Note: The possibly sensible smell is not caused by droplets of oil, though, but either by gaseous process components or by readily volatile and thus gaseous components of the oil (particularly additives).

Noise Emission

For the sound pressure level in free field according to EN ISO 2151  page 2: Technical Data.

5. Transport

Note: Also a vacuum pump, that is not topped up with oil

contains residues of oil (from the test run). Always transport and store the vacuum pump in upright position. Do not put the vacuum pump on its side or put it upside down.

Transport in Packaging

Packed on a pallet the vacuum pump is to be transported with a forklift.

Transport without Packaging

In case the vacuum pump is packed in a cardboard box with inflated cushions:  Remove the inflated cushions from the box

In case the vacuum pump is in a cardboard box cushioned with rolled corrugated cardboard:  Remove the corrugated cardboard from the box

In case the vacuum pump is laid in foam:  Remove the foam

In case the vacuum pump is bolted to a pallet or a base plate:  Remove the bolting between the vacuum pump and the

pallet/ base plate

In case the vacuum pump is fastened to the pallet by means of tightening straps:

 Remove the tightening straps

 Make sure that the eyebolt (k, 391) is in faultless condition

(replace a damaged, e.g. bent eyebolt with a new one)

 Make sure that the eyebolt (k, 391) is fully screwed in and

tightened by hand

 Attach lifting gear securely to the eyebolt (k, 391) on the oil

separator

 Attach the lifting gear to a crane hook with safety latch  Lift the vacuum pump with a crane

In case the vacuum pump was bolted to a pallet or a base plate:

o Remove the stud bolts from the rubber feet

 Prior to every transport make sure that the oil is

drained

6. Storage

Short-term Storage

Version with gas ballast with ball-valve:

 Make sure that the ball-valve of the gas ballast device

(440) is closed

Version with gas ballast without ball-valve, with sinter metal filter:  Close the sinter metal filter of the gas ballast device (440)

with adhesive tape

 Make sure that the suction connection and the gas

discharge are closed (leave the provided plugs in)

 Store the vacuum pump

o if possible in original packaging, o indoors, o dry, o dust free and

o vibration free

Conservation

In case of adverse ambient conditions (e.g. aggressive atmosphere, frequent temperature changes) conserve the vacuum pump immediately. In case of favourable ambient conditions conserve the vacuum pump if a storage of more than 3 months is scheduled.

During the test run in the factory the inside of the vacuum pump was completely wetted withoil. Under normal conditions a treatment with conservation oil is therefore not required. In case it is advisable to treat the vacuum pump with conservation oil because of very adverse storage conditions, seek advice from your Schmalz representative!

Version with gas ballast with ball-valve:  Make sure that the ball-valve of the gas ballast (440) is

closed

 Version with gas ballast without ball-valve, with sinter

metal filter:

 Close the sinter metal filter of the gas ballast (440) with

adhesive tape

 Make sure that all ports are firmly closed; seal all ports that

are not sealed with PTFE-tape, gaskets or o-rings with adhesive tape

Note: VCI stands for “volatile corrosion inhibitor”. VCI-products (film, paper, cardboard, foam) evaporate a substance that condenses in molecular thickness on the packed good and by its electro-chemical properties effectively suppresses corrosion on metallic surfaces. However, VCI-products may attack the surfaces of plastics and elastomers. Seek advice from your local packaging dealer! Schmalz uses CORTEC VCI 126 R film for the overseas packaging of large equipment.

 Wrap the vacuum pump in VCI film  Store the vacuum pump

o if possible in original packing, o indoors, o dry, o dust free and o vibration free.

For commissioning after conservation:  Make sure that all remains of adhesive tape are removed

from the ports

 Commission the vacuum pump as described in the chapter

Installation and Commissioning (page 6)

7. Installation and Commissioning

Installation Prerequisites

 Make sure that the integration of the vacuum pump is

carried out such that the essential safety requirements of the Machine Directive 2006/42/EC are complied with (in the responsibility of the designer of the machinery into which the vacuum pump is to be incorporated;  page 24: note in the EC-Declaration of Conformity)

Mounting Position and Space

 Make sure that the environment of the vacuum pump is not

potentially explosive

 Make sure that the following ambient conditions will be

complied with:

 ambient temperature: see “Oil”

If the vacuum pump is installed in a colder environment than allowed with the oil used:  Fit the vacuum pump either with an oil sump heating

(on request) or fit the vacuum pump with a temperature switch and control the vacuum pump such that it will start automatically when the oil sump temperature falls below the allowed temperature

 ambient pressure: atmospheric  Make sure that the environmental conditions comply with

the protection class of the drive motor (according to the nameplate)

 Make sure that the vacuum pump will be placed or

mounted horizontally

 Make sure that in order to warrant a sufficient cooling there

will be a clearance of minimum 20 cm between the vacuum pump and nearby walls

 Make sure that no heat sensitive parts (plastics, wood,

cardboard, paper, electronics) will touch the surface of the vacuum pump

 Make sure that the installation space or location is vented

such that a sufficient cooling of the vacuum pump is warranted

 Make sure that the vacuum pump will not be touched

inadvertently during operation, provide a guard if appropriate

 Make sure that the sight glass (m, 83) will remain easily

accessible

If the oil change is meant to be performed on location:

 Make sure that the drain port (n, 95), the oil filter (h,

100) and the filling port (l, 88) will remain easily accessible

 Make sure that enough space will remain for the removal

and the reinsertion of the exhaust filter (p, 120)

Suction Connection

In case the inlet gas can contain dust or other foreign solid particles:

 Make sure that a suitable filter (5 micron or less) is

installed upstream the vacuum pump

 Make sure that the suction line fits to the suction

connection (d, 260) of the vacuum pump

 Make sure that the gas will be sucked through a vacuum-

tight flexible hose or a pipe

In case of using a pipe:

 Make sure that the pipe will cause no stress on the

vacuum pump’s connection, if necessary use an expansion joint

 Make sure that the line size of the suction line over the

entire length is at least as large as the suction connection (d, 260) of the vacuum pump

In case of very long suction lines it is prudent to use larger line sizes in order to avoid a loss of efficiency. Seek advice from your Schmalz representative!

If two or more vacuum pumps work on the same suction line, if the volume of the vacuum system is large enough to suck back oil or if the vacuum shall be maintained after switching off the vacuum pump:

 Provide a manual or automatic operated valve (= non-

return valve) in the suction line

(the standard non-return valve that is installed inside the suction connection is not meant to be used for this purpose!)

If the vacuum pump is planned to be used for the suction of gas that contains limited quantities of condensable vapour:

 Provide a shut-off valve, a drip-leg and a drain cock in

the suction line, so that condensates can be drained from the suction line

 Make sure that the suction line does not contain foreign

objects, e.g. welding scales

Gas Discharge

The discharged gas must flow without obstruction. It is not permitted to shut off or throttle the discharge line or to use it as a pressurised air source.

The following guidelines for the discharge line do not apply, if the aspirated air is discharged to the environment right at the vacuum pump.

 Make sure that the discharge line fits to the gas discharge

(c, 155) of the vacuum pump In case of using a pipe:  Make sure that the pipe will cause no stress on the

vacuum pump’s connection, if necessary use an

expansion joint  Make sure that the line size of the discharge line over the

entire length is at least as large as the gas discharge (c,

155) of the vacuum pump

In case the length of the discharge line exceeds 2 m it is prudent to use larger line sizes in order to avoid a loss of efficiency and an overload of the vacuum pump. Seek advice from your Schmalz representative! With unrestricted suction the counter pressure at the gas discharge (c, 155) of the vacuum pump must not exceed 1.3 bar abs (in case of doubt to be verified during commissioning at a suitable time).

 Make sure that the discharge line either slopes away from

the vacuum pump or provide a liquid separator or a drip leg with a drain cock, so that no liquids can back up into the vacuum pump

Electrical Connection / Controls

 Make sure that the stipulations acc. to the EMC-Directive

2004/108/EC and Low-Voltage-Directive 2006/95/EC as well as the EN-standards, electrical and occupational safety directives, the local or national regulations, respectively, are complied with (this is the responsibility of the designer of the machinery into which the vacuum pump is to be incorporated; page 24: note in the EC-Declaration of Conformity).

 Make sure that the power supply for the drive motor is

compatible with the data on the nameplate of the drive motor (400)

 Make sure that an overload protection according to EN

60204-1 is provided for the drive motor

 Make sure that the drive of the vacuum pump will not be

affected by electric or electromagnetic disturbance from the

mains; if necessary seek advice from the Schmalz service In case of mobile installation:

 Provide the electrical connection with grommets that serve

as strain-relief

Connecting Lines/Pipes

In case the suction line is equipped with a shut-off valve:

 Connect the suction line  Connect the discharge line

Installation without discharge line:

 Make sure that the gas discharge (c, 155) is open  Make sure that all provided covers, guards, hoods etc. are

mounted  Make sure that cooling air inlets and outlets are not covered

or obstructed and that the cooling air flow is not affected

adversely in any other way

Filling Oil

In case the vacuum pump was treated with conservation oil:  Drain the remainders of conservation oil

The vacuum pump is delivered without oil (oil specification  page 23: Oil).

 Keep approx. 1.0 litres oil acc. to the table Oil (_ page 23)

ready Note: The amount given in these operating instructions is a

guide. The sight glass (m, 83) indicates the actual amount to be filled in.

 Remove the filling plug (l, 88)  Fill in approx. 1.0 litres of oil  Make sure that the level is between the MIN and the MAX-

markings of the sight glass (m, 83)  Make sure that the seal ring (89) is inserted into the filling

plug (l, 88) and undamaged, replace if necessary  Firmly reinsert the filling plug (l, 88) together with the seal

ring (89) Note: Starting the vacuum pump with cold oil is made easier

when at this very moment the suction line is neither closed nor covered with a rubber mat.

 Switch on the vacuum pump In case the suction line is equipped with a shut-off valve:

 Close the shut-off valve In case the suction line is not equipped with a shut-off valve:

 Cover the suction connection (d, 260) with a piece of

rubber mat

 Let the vacuum pump run for a few minutes

 Shut down the vacuum pump and wait a few minutes  Check that the level is between the MIN and the MAX-

markings of the sight glass (m, 83)

In case the level has dropped below the MIN-marking:

 Top-up oil

In case the suction line is equipped with a shut-off valve:

 Open the shut-off valve

In case the suction line is not equipped with a shut-off valve:

 Remove the piece of rubber mat and connect the suction

line

Recording of Operational Parameters

As soon as the vacuum pump is operated under normal operating conditions:

 Measure the drive motor current and record it as reference

for future maintenance and troubleshooting work

Version with exhaust filter pressure gauge:

 Read the scale of the exhaust filter pressure gauge and

record it as reference for future maintenance and trouble-shooting work ( page 11: Checks during Operation)

Operation Notes

Use

The vacuum pump is intended for

- the suction of

- air and other dry, non-aggressive, non-toxic and nonexplosive gases.

Conveying media with a lower or higher density than air leads to an increased thermal and/or mechanical load on the vacuum pump and is permissible only after prior consultation with Schmalz.

Permissible temperature range of the inlet gas: see “Oil”, “Ambient temperature range”

The vacuum pump is intended for the placement in a nonpotentially explosive environment.

Version with float valve (j, 200) and oil return line: The vacuum pump is thermally suitable for continuous operation (100 percent duty).

Version with oil return valve (f, 280): The vacuum pump is thermally suitable for continuous operation (observe the notes with regard to the oil recirculation:  page 4: Oil Circulation; page 9: Oil Return).

The vacuum pump is ultimate pressure proof.

 Make sure that all provided covers, guards, hoods etc.

remain mounted

 Make sure that protective devices will not be disabled  Make sure that cooling air inlets and outlets will not be

covered or obstructed and that the cooling air flow will not be

affected adversely in any other way

 Make sure that the installation prerequisites (page 6:

Installation Prerequisites) are complied with and will remain

complied with, particularly that a sufficient cooling will be

ensured

Oil Return

Only for version with oil return valve (f, 280): During operation oil accumulates at the bottom of the upper

chamber of the oil separator (o, 75), which cannot flow down into the bottom chamber, as long as the vacuum pump runs (for detailed description: page 4: Oil Circulation).

At the latest after 10 hours of continuous operation, in case of high pressure difference between suction side and pressure side after a shorter period, the vacuum pump must be shut down for at least 15 minutes, so that the oil can run down from the upper chamber of the oil separator (o, 75) into the bottom chamber.Note:

This is a good time to check the temperature, the level and the colour of the oil.

Conveying Condensable Vapours

Version with gas ballast with ball-valve:  Make sure that the gas ballast valve is open and will remain

open during operation

 Close the shut-off valve in the suction line  Operate the vacuum pump with the suction line shut off for

approx. half an hour, so that the operating temperature rises

to approx. 75 °C At process start:

 Open the shut-off valve in the suction line At the process end:

 Close the shut-off valve in the suction line

 Operate the vacuum pump for another approx. half an hour

8. Maintenance

 Prior to action that requires touching of the vacuum pump,

let the vacuum pump cool down, however, if the oil is to be drained, for no more than 20 minutes (the oil shall still be warm when being drained)

 Prior to disconnecting connections make sure that the

connected pipes/lines are vented to atmospheric pressure

8.1 Maintenance Schedule

Note: The maintenance intervals depend very much on the

individual operating conditions. The intervals given below shall be considered as starting values which should be shortened or extended as appropriate. Particularly heavy duty operation, such like high dust loads in the environment or in the process gas, other contaminations or ingress of process material, can make it

necessary to shorten the maintenance intervals significantly.

Daily: Check the level and the colour of the oil ( page 10:

Checking the Oil)

Weekly: Check the vacuum pump for oil leaks - in case of

leaks have the vacuum pump repaired (Schmalz service)

Monthly: Check the function of the exhaust filter (p, 120)

(page 11: Exhaust Filter) Make sure that the vacuum pump is shut down and locked against inadvertent start up

In case an inlet air filter is installed:

 Check the inlet air filter, if necessary replace

In case of operation in a dusty environment:  Clean as described  page 9: Every 6

Months:

Every 6 Months: Make sure that the housing is free from dust

and dirt, clean if necessary

Make sure that the vacuum pump is shut

down and locked against inadvertent start up

Clean the fan cowlings, fan wheels, the

ventilation grilles and cooling fins

Every Year: Make sure that the vacuum pump is shut down

and locked against inadvertent start up Replace the exhaust filter (p, 120) (_ page 11:

Exhaust Filter)

In case an inlet air filter is installed: Replace the inlet air filter Check the inlet screen (261), clean if necessary

Version with gas ballast (440) with sinter metal filter: Clean the sinter metal filter (compressed air)

Every 500 - 2000 Operating Hours (page 10: Oil Life):

Change the oil and the oil filter (h, 100) (

page 10: Oil and Oil Filter Change)

Version with float valve (j, 200) and oil return line:

Check the float valve (j, 200) ( page 11: Checking the Float Valve)

Checking the Oil

Checking the Level

 Make sure that the vacuum pump is shut down and the oil

has collected at the bottom of the oil separator (o, 75)

 Read the level on the sight glass (m, 83) In case the level has dropped underneath the MIN-marking:

 Top up oil ( page 10: Topping up Oil) In case the level exceeds the MAX-marking:

 Excessive dilution with condensates - change the oil and

check the process

 If appropriate retrofit a gas ballast (Schmalz Service) and

observe the chapter Conveying Condensable Vapours ( page 9)

In case the level exceeds the MAX-marking despite proper use of the gas ballast:

 Clean the sinter metal filter (compressed air)

Topping up Oil

Note: Under normal conditions there should be no need to top

up oil during the recommended oil change intervals. A significant level drop indicates a malfunction ( page 14: Troubleshooting).

Note: During operation the exhaust filter gets saturated with oil.

It is therefore normal that the oil level will drop slightly after replacement of the exhaust filter.

 Make sure that the vacuum pump is shut down and locked

against inadvertent start up

 Remove the filling plug (l, 88)  Top up oil until the level reaches the middle of the sight

glass (m, 83)

 Make sure that the seal ring (89) is inserted into the filling

plug (l,88) and undamaged, replace if necessary

 Firmly reinsert the filling plug (l, 88) together with the seal

ring (89)

Checking the Colour of the Oil

Note: The oil should be light, either transparent, a little foamy or

a little tarnished. A milky discolouration that does not vanish after sedation of the oil indicates contamination with foreign material. Oil that is either contaminated with foreign material or burnt must be changed ( page 10: Oil and Oil Filter Change).

In case the oil appears to be contaminated with water or other condensates despite proper use of the gas ballast:  Clean the sinter metal filter (compressed air)

Oil Life

The oil life depends very much on the operating conditions. A clean and dry air stream and operating temperatures below 100 °C are ideal. Under these conditions the oil and the oil filter (h, 100) shall be changed every 500 to 2000 operating hours or after half a year.

Under very unfavourable operating conditions the oil life can be less than 500 operating hours. Extremely short life times indicate malfunctions ( page 14: Troubleshooting) or unsuitable operating conditions, though.

Chosing a synthetic oil instead of a mineral oil can extend the oil life. To select the oil best suited oil for your process please contact your Schmalz representative.

If there is no experience available with regard to the oil life under the prevailing operation conditions, it is recommended to have an oil analysis carried out every 500 operating hours and establish the change interval accordingly.

Oil and Oil Filter Change

Draining Used Oil

Note: After switching off the vacuum pump at normal operating

temperature wait no more than 20 minutes before the oil is drained (the oilshall still be warm when being drained).

 Make sure that the vacuum pump is shut down and locked

against inadvertent start up

 Make sure that the vacuum pump is vented to atmospheric

pressure

 Put a drain tray underneath the drain port (n, 95)  Remove the drain plug (n, 95) and drain the oil

When the oil stream dwindles:

 Reinsert the drain plug (n, 95)  Switch the vacuum pump on for a few seconds  Make sure that the vacuum pump is shut down and locked

against inadvertent start up

 Remove the drain plug (n, 95) again and drain the

remaining oil

 Make sure that the seal ring (96) is inserted into the drain

plug (n, 95) and undamaged, replace if necessary

 Firmly reinsert the drain plug (n, 95) together with the seal

ring (96)

 Dispose of the used oil in compliance with applicable

regulations

Flushing the Vacuum Pump

 Make sure that all the used oil is drained  Make sure that the used oil filter (h, 100) is still in place  Create 1.0 litres flushing agent from 50 percent oil and 50

percent paraffin or diesel fuel/fuel oil

 Make sure that the drain plug (n, 95) is firmly inserted  Remove the filling plug (l, 88)  Fill in the flushing agent  Firmly reinsert the filling plug (l, 88)  Close the suction line  Run the vacuum pump for at least half an hour  Drain the flushing agent and dispose of it in compliance

with applicable regulations

Note: Due to the use of paraffin and even more in case of using diesel fuel/fuel oil, an unpleasant odour can occur after recommissioning. If this is a problem, diesel fuel/fuel oil should be avoided and the vacuum pump be run at idle in a suitable

place until the unpleasant odour vanishes.

Checking the Float Valve

(version with float valve and oil return line only)

Note: It is essential that the float valve (j, 200) works properly, so that the vacuum pump will achieve the intended ultimate pressure and no oil will be expelled out of the gas discharge (c, 155).

 Make sure that the vacuum pump is shut down and locked

against inadvertent start up

 Prior to disconnecting pipes/lines make sure that the

connected pipes/lines are vented to atmospheric pressure

 Remove the discharge line, if necessary  Remove the exhaust cover (c, 155)  Remove the oil from the floater chamber with the aid of a

suction hose or a wash bottle

 Undo the screws (341) and remove the fan cover (e, 340) Note: While undoing the banjo fitting of the oil return line (j, 195)

a small amount of oil will leak out: keep a cleaning rag ready. Be careful not to lose the sealing rings of the banjo fitting.

 Undo the banjo fitting of the oil return line (j, 195) from the

oil separator (o, 75) and bend the oil return line a little bit aside

 Undo the two screws of the flange of the float valve (j, 200)

and pull the float valve out of the oil separator (o, 75)

 Check the cleanliness and function of the float valve (j,

200), blow out with compressed air, if necessary

 Make sure that the o-ring on the flange of the float valve (j,

200) is in place and undamaged, replace with a new oring, if necessary

 Insert the float valve (j, 200) in the proper orientation into

the oil separator (o, 75) and fasten it with two screws and lock washers

 Connect the banjo fitting of the oil return line (j, 195) to the

oil separator (o, 75) with the hollow-core screw and two seal rings

 Fasten the fan cover (e, 340) to the vacuum pump with the

screws (341)

Only if the exhaust filter (p, 120) is not meant to be changed, too:  Make sure that the seal (141) under the exhaust cover (c,

155) is clean and undamaged, if necessary replace with a new seal (141)

 Mount the exhaust cover (c, 155) together with the seal

(141), hex head screws (146) and lock washers on the oil separator (o, 75)

 If necessary connect the discharge line

Replacing the Oil Filter

 Make sure that the oil is drained  Remove the oil filter (h, 100)  Apply a drop of fresh oil on the seal ring of the new oil filter

(h, 100)

 Mount the new oil filter (h, 100) and tighten it by hand  Dispose of the used oil filter in compliance with applicable

regulations

Filling in Fresh Oil

 Keep 1.0 litres oil acc. to the table Oil ( page 23) ready

Note: The amount given in these operating instructions is a guide. The sight glass (m, 83) indicates the actual amount to be filled in.

 Make sure that the drain plug (n, 95) is firmly inserted

 Remove the filling plug (l, 88)  Fill in approx. 1.0 litres of oil  Make sure that the level is between the MIN and the MAX-

markings of the sight glass (m, 83)

 Make sure that the seal ring (89) is inserted into the filling

plug (l, 88) and undamaged, replace if necessary

 Firmly reinsert the filling plug (l, 88) together with the seal

ring (89)

Exhaust Filter

Checks during Operation

Schmalz recommends the use of a filter pressure gauge (available as accessory,  page 21: Accessories). Without filter pressure gauge the filter resistance shall be assessed on the basis of the drive motor current drawn.

Version with exhaust filter pressure gauge:  Remove the suction line from the suction connection (d,

260) (unrestricted suction!)

 Make sure that the vacuum pump is running  Check that the reading on the filter pressure gauge is in

the green field

 Reconnect the suction line to the suction connection (d,

260)

Version without filter pressure gauge:

 Make sure that the vacuum pump is running  Check that the drive motor current drawn is in the usual

range Version with oil return valve (f, 280)

Note: The discharged gas will also contain oil if the vacuum pump is operated without interruption for too long a period ( page 8: Operation Notes).

 Check that the discharged gas is free from oil

Assessment

If the reading on the filter pressure gauge is in the red field, or the drive motor draws too much current and/or the pump flow rate has dropped, then the exhaust filter (p, 120) is clogged and must be replaced.

Note: Exhaust filters cannot be cleaned successfully. Clogged exhaust filters must be replaced with new ones.

If the filter pressure gauge indicates a lower pressure than usual, or the drive motor draws less current than usual, then the exhaust filter (p, 120) is broken through and must be replaced. If the discharged gas contains oil,

the exhaust filter (p, 120) can either be clogged or broken through and, if applicable, must be replaced.

Change of the Exhaust Filter

Removing the Exhaust Filter

 Make sure that the vacuum pump is shut down and locked

against inadvertent start up

 Prior to disconnecting pipes/lines make sure that the

connected pipes/lines are vented to atmospheric pressure

 Remove the discharge line, if necessary  Remove the exhaust cover (c, 155) from the oil separator

(o, 75)

 Loosen the screw in the centre of the exhaust filter

retaining spring (125), but do not remove it at this time

 Press the exhaust filter retaining spring (125) out of the

indent and rotate it

 Remove the exhaust filter retaining spring (125) from the

oil separator (o, 75)

 Pull the exhaust filter (p, 120) out of the oil separator (o,

75)

Inserting the Exhaust Filter

 Make sure that the new exhaust filter (p, 120) is equipped

with a new o-ring

 Insert the exhaust filter (p, 120) such that its port is

properly seated in its receptacle in the oil separator (n, 75)

 Make sure that the tip of the screw in the centre of the

exhaust filter retaining spring (125) protrudes the retaining spring by about 2 - 5 revolutions

 Insert the exhaust filter retaining spring (125) such that its

ends are secured in their receptacles in the oil separator (o, 75) by the protrusions and that the tip of the screw snaps into the indent of the exhaust filter (p, 120)

 Tighten the screw in the exhaust filter retaining spring

(125) such that the screw head touches the spring steel sheet

 Make sure that the seal (141) under the exhaust cover (c,

155) is clean and undamaged, if necessary replace with a new seal (141)

 Mount the exhaust cover (c, 155) together with the seal

(141), hex head screws (146) and lock washers on the oil separator (o, 75)

 If necessary connect the discharge line Note: During operation the exhaust filter gets saturated with oil.

It is therefore normal that the oil level will drop slightly after replacement of the exhaust filter.

9. Overhaul

Schmalz service will only accept vacuum pumps that come with

a completely filled in and legally binding signed “Declaration of Contamination”

10. Removal from Service

Temporary Removal from Service
