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.

Max. allowed temperature of the inlet gas: 40 °C
Standard-version:

The gas shall be free from vapours that would condensate under
the temperature and pressure conditions inside the vacuum
pump.

Version “Aqua”:

The vacuum pump features the corrosion protection coating
CPC and is capable of conveying water vapour ➔ page 9:
Conveying Condensable Vapours). Conveyance of other
vapours shall be agreed upon with Schmalz. Conveyance of
water or other liquids in liquid phase increases the power
consumption and shall therefore be avoided (risk of drive

overload).
The vacuum pump is intended for the placement in a non-potentially
explosive environment.

Max. permissible number of startings per hour: 12
Vacuum pumps MM 1324 AV standard-version are thermally

suitable for continuous operation down to ultimate pressure.

Vacuum pumps MM 1324 AV Version “Aqua” are thermally suitable
for continuous operation at intake pressures down to 200 hPa abs
(200 mbar abs). By means of process control and/or vacuum relief
valves it must be made sure that the minimum allowed intake
pressure will not be underrun.

Vacuum pumps MM 1202 AV, MM 1200 AV, MM 1252 AV and
MM 1250 AV are thermally suitable for continuous operation at
intake pressures down to 100 hPa abs (100 mbar abs). By means of
process control and/or vacuum relief valves it must be made sure
that the minimum allowed intake pressure will not be underrun.

Vacuum pumps MM 1322 AV and MM 1320 AV (version
600…3600 min-1) are thermally suitable for continuous operation at
intake pressures down to 150 hPa abs (150 mbar abs). MM 1320 AV
(version 600…4200 min-1) are thermally suitable for continuous
operation at intake pressures down to 200 hPa abs (200 mbar abs).
By means of process control and/or vacuum relief valves it must be
made sure that the minimum allowed intake pressure will not be
underrun.

Version “Aqua”:

The safety valve on the vacuum pump protects the vacuum
pump against overheating only. It is not designed for frequent
use and must therefore not be used as a system pressure
regulating valve.

Principle of Operation

The vacuum pump works on the claw principle.
The components are dimensioned such, that on the one hand there

is never contact between the two claws or between a claw and the
cylinder, on the other hand the gaps are small enough to keep the
clearance loss between the chambers low.

In order to avoid the suction of solids, the vacuum pump is equipped
with a screen (715) in the suction connection.

In order to avoid reverse rotation after switching off, the vacuum
pump is equipped with a non-return valve (o, 714).

Seite 4 30.30.01.00867-00_EN / 04.2015

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

♦ Remove the stud bolts from the rubber feet

Storage

Short-term Storage

• Make sure that the suction connection and the gas discharge
are closed (leave the provided plugs in)

• Store the vacuum pump

− If possible in original packaging,

− indoors,

− dry,

− dust free and

− 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.

• 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

− If possible in original packaging,

− indoors,

− dry,

− dust free and

− vibration free.

Installation and Commissioning

Suction Connection

CAUTION
Intruding foreign objects or liquids can destroy the vacuum

pump.

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
(g/p) 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 (g/p) of the
vacuum pump

In case the length of the suction 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!

In case the vacuum pump shall be maintained after shutdown of the
vacuum pump:

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

return valve) in the suction line

Version “Aqua”, if very humid process gases and/or adverse
operating cycles bear the risk, that condensates remain in the
vacuum pump:

♦ 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

♦ Provide a valve for the unthrottled suction of ambient air

(ambient air valve) between the shut-off valve and the
vacuum pump (in order to dry the vacuum pump after
process end)

♦ For non ultimate-pressure-proof vacuum pumps provide a

vacuum relief valve (suitable for continuous operation) for
the throttled aspiration of ambient air during warming up

♦ Make sure that the anti-pulsation chamber is equipped

with a condensate drain cock (j) (optional; if the
condensate drain cock is missing contact the Schmalz
service)

• Make sure that the suction line does not contain foreign
objects, e.g. welding scales

• Make sure that the line size of the discharge line over the entire
length is at least 2”

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!

• 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

contaminated with foreign materials which are dangerous
to health, harmful material can reside in filters.

Danger to health during inspection, cleaning or
replacement of filters.

Danger to the environment.
Personal protective equipment must be worn during the

handling of contaminated filters.
Contaminated filters are special waste and must be

disposed of separately in compliance with applicable
regulations.

CAUTION
During operation the surface of the vacuum pump may reach

temperatures of more than 70 °C.
Risk of burns!

• Prior to disconnecting connections make sure that the
connected pipes/lines are vented to atmospheric pressure

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.

Monthly

• Make sure that the vacuum pump is shut down and locked
against inadvertent start up

In case an inlet air filter (h) is installed:

♦ Check the inlet air filter (h), if necessary replace

In case of operation in a dusty environment:

♦ Clean as described under ➔ page 9: Every 6 Months

Every 3 Months:

• Make sure that the vacuum pump is shut down and locked
against inadvertent start up

• Check the level and the colour of the synchronising gear oil

The level shall be slightly above the middle of the sight glass (e, 76).
The level of the synchronising gear should stay constant over the

lifetime of the oil. If the level does fall, the gear is leaky and the
vacuum pump requires repair (Schmalz service).

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
