Product description
4.2 Function
The operating principle of the Roots pumps is based on two synchronous pistons which
rotate in a housing without touching. The pumping effects arise as a result of the opposing rotation of the two figure-of-eight shaped rolling pistons. While suction chambers are
formed between the rolling pistons and the housing, the rolling pistons continuously form
a mutual seal without touching each other or the housing. This opposing yet synchronised movement of the rolling pistons is achieved by means of a pair of gears mounted
on the extended shaft ends. Lubrication is limited to the two bearing and gear chambers
which are arranged separately from the suction chambers. As the Roots pump is not capable of compressing against atmospheric pressure it needs to be operated in conjunction with an upstream backing pump.
A bypass valve that is either cast into or bolted to the housing protects the pump against
overheating.

Toxic vapours!
Danger of poisoning when igniting and heating synthetic operating fluids (e.g. F4/F5)
above 300 °C.
Observe the application instructions.
Do not allow operating fluid to make contact with tobacco products; observe safety
precautions when handling chemicals.
The shaft feedthrough of the drive shaft is sealed with sealing oil-covered radial shaft
seals, and is fed by an oiler 18. The type of sealing oil is the same as the lubricant.
Fill up oiler to halfway with lubricant.
– Oiler 18 should always be filled to a max. of halfway (when the pump is cold); top
up as required.
The lubricant expands when the pump heats up, which could cause lubricant to
leak if the oiler is overfilled.
When using a mechanical seal (optional), a cooling of the sealing surfaces is required.
The sealant reservoir needs to be attached above the shaft feedthrough on the outside
of the pump, on the base frame or in a different suitable location depending on the actual
conditions. The mechanical seal is capable of bridging a certain pipe resistance through
its own pumping effect. If the supply of sealant is no longer guaranteed, an additional circulation pump must be installed. The pipes and the sealant reservoir are not contained
in the scope of supply.
12
During assembly of the sealant reservoir observe the installation instructions supplied
by the manufacturer.
Use the sealant in accordance with the manufacturer's instructions.
Cooling the mechanical seal
The ambient temperatures to which the pump is exposed will vary depending on the location in which it is being used. If the cooling of the sealant (max. +90 °C) is not sufficient
for the amount of heat radiated at the sealant reservoir, then an additional water cooling
system (25) will need to be connected.

5.3 Connecting the vacuum side
Exposed, rotating rolling pistons!
Fingers and hands can become crushed when the intake flange is open.
Keep all body parts out of operating range of the rolling pistons.
Use a wooden handle to rotate the rolling pistons during cleaning.
The connection between the pump and the vacuum chamber should be kept as short
as possible and should have at least the nominal diameter of the pump flange. Use a
greater nominal diameter on line lengths > 5 m.
Piping to the pump must be suspended or supported.
– Physical forces from the piping system must not be allowed to act on vacuum
pumps.
Clear welded lines of any welding scales, loose parts etc. before installation.
Danger of intake of solid particles!
Even in clean processes, fouling from the system must be anticipated during initial commissioning.
Use a suitable start-up strainer at the intake connection (see accessories).
Ensure that this strainer is only removed when the risk of solid particles entering the
pump can be excluded.
Note loss of pumping speed if necessary.
WARNING
NOTICE
5.4 Connecting the fore-vacuum side
Choose the cross-section of the exhaust line to be at least the size of the nominal
connection diameter of the Roots pump’s exhaust flange.
Lay the pipes in such a way that the Roots or backing pump will not be subjected to
any mechanical tension.
– Suspension components should be integrated into the piping.
– Ensure that mating flanges are in a parallel position.
Lay piping from the pump sloping downward so that no condensate can flow back into
the pump; otherwise fit a condensate separator.
– If an air trap is created in the system, then a device for draining condensation water
must be provided at the lowest point.
WARNING
Emission of toxic substances from the exhaust!
Danger of poisoning from emitted gases or vapours, which can be detrimental to health
and/or can pollute the environment, depending on the particular application.
Comply with the applicable regulations when working with toxic substances.
Only officially approved filter systems may be used to separate and remove these
substances.

DANGER
Voltage-bearing elements
Danger to life from electric shock.
The electrical connection can be carried out only by trained and authorised electri-
cians.
Disconnect the power supply and secure it against being switched back on.
Ensure the system is adequately earthed.
NOTICE
Excess voltage!
Danger of destroying the motor.
Power connections must comply with local regulations. Voltage and frequency infor-
mation given on the motor rating plate must correspond to the mains voltage and frequency values.
To protect the motor and supply cable in case of malfunction, mains fuse protection
must be implemented. Recommended: Type K slow blow circuit breaker.
NOTICE
Thermal motor overload!
Inadequate cooling at low motor speeds.
When operating the pump with frequency converter, follow the rotation speed range,
specified in the technical data.
The three-phase current motor circuit
The direction of rotation must be checked on pumps with three-phase motors!
The connections U1 - L2, V1 - L1 and W1 - L3 result in a clockwise rotation of the motor
shaft as seen looking towards the motor fan.
Delta Connection
The three coils are connected in series with the connection point connected to the mains.
The voltage of each coil is the same as the mains voltage whereas the mains current is
the cube root of the coil current. Delta connections are denoted by the symbol ∆. The
voltage between the mains supply lines is called mains voltage. The mains current is the
current which flows in the supply lines.
Fig. 6: Motor coil and connecting plate of Delta Connection (for low voltage)
Star Connection
The ends of the three coils are connected at the star center. The terminal voltage is the
cube root of the coil voltage; the mains and the coil current are the same. Star connections are denoted by the symbol Y.

Visual inspection of the direction of rotation
Check the direction of rotation of the pump after switching on for the first time:
– To do this, switch the pump briefly ON and OFF again (for a max. of 5 seconds).
Compare the direction of rotation of the motor and the motor ventilator with the direc-
tional arrow on the housing cover.
– Looking from the motor side, the correct direction of rotation is to the right in a clock-
wise direction.
If the direction of rotation is incorrect: Swap two of the three phase contacts at the con-
necting cable.
Fig. 8: Checking the direction of rotation
Motor protection With PTC temperature sensors (3PTC)
Pump motors equipped with PTC temperature sensors (3PTC) in the stator windings can
be connected to a PTC resistor tripping device for protection against overload. Other approved motor temperature monitoring can be used also by the operator.
Tripping devices store the shutdown event and need to be manually switched back on
again via the integrated RESET button or via the external RESET S3. Mains-ON is detected as an automatic RESET.
Set up the connections so that the directional rotation indicated on the pump is main-
tained, regardless of the representations in the current flow diagram.

5.6 Connecting accessories
The following accessories are not included in the delivery, and can be ordered separately:
Sealing gas connection
The evacuation of high-boiling media (e.g. solvents) can be damaging to the lubricant.
Damage can be avoided by letting in sealing gas (process-specifically) into the shaft passageways between the operating chamber and the gear chamber.
The sealing gas line should be connected at both connections of each bearing bracket
(4 x G 3/8").
Connect gas cylinder 325 with pressure reducer 324 to flow meter 315, adjust amount
of sealing gas (see p. 20, chap. 6.2)

Using a flushing device
Fig. 10: Connecting sealing gas
Depending on requirements, the Roots pump can be flushed continuously or temporari-
ly(see p. 20, chap. 6.2), if the evacuated medium is causing severe contamination or de-
posits in the suction chamber. The injection nozzle is set to the maximum fluid quantity
of the pump at a pressure of 3000 hPa.
NOTICE
Risk of damage to the pump!
During the flushing and cleaning procedure the flushing liquid and the process medium
can pass over into the bearings and oil chambers and can stick there.
To protect the bearings during cleaning, sealing gas must always be used.
Attach flushing adapter to the vacuum flange.
For sealing and throughflow monitoring install a shut-off valve and a flow meter with
dosing valve into the inflowing line.

Installation
Installing a protective
strainer
Attaching gear chamber extraction
If there is a risk that solid particles will be carried along in the evacuation process then a
protective strainer should be installed in the intake connection piece to protect the Roots
pump (see accessories).
When the vacuum chamber is evacuated quickly (<1 min), each of the gear chambers
should be pumped out via an oil separator in the connection line to the fore-vacuum side.
Do this as follows:
Unscrew both lubricant filler screws (G 3/4") and the blanking plug from the pressure-
side measurement connection (G 3/8"); check the O-rings.
Instead of the filler screws, screw in screw couplings with e.g. small screw-in flanges
(DN 10 KF); use O-rings.
Flange on both oil separators and install the lines.

6Operation
6.1 Before switching on the pump
Check lubricant levels at both sight glasses and at the oiler as well.
Operate shut-off units in the exhaust line in such a way that they open before or at the
same time as starting the pump.
Protect the pump sufficiently from taking in contaminants by means of suitable precau-
tions (e.g. protective strainer); if necessary, check lubricant regularly or replace at
shorter intervals.
Check pump for visible damage and only start up if it is in the correct condition.
Ensure that the suction chamber is free of foreign particles.
6.2 Switching on the pump
Hot surface!
Danger of burns if hot parts are touched. Depending on the operating and ambient conditions, the surface temperature of the pump may rise above 100 °C.
In this case, use suitable finger guards.
CAUTION
Operation with
frequency converter (FU)
Adjusting the amount
of sealing gas
Switch on the Roots pump at the same time as the backing pump or after the backing
pump;
– switch off Roots pump in the event of failure of the backing pump.
The overflow valve is open at the beginning of evacuation in the high pressure range. It
protects the Roots pump from thermal overload. The overflow valve closes starting at a
differential pressure below 7 mbar between the suction side and the compression side.
To protect the pump against overheating, the operation with frequency converter allows
torque-dependant control of the pump speed.
The permissible speed range (20 Hz < n < 75 Hz) must be observed to ensure reliable
bearing lubrication. To protect the pump from damage, an alarm must be triggered and
the pump stopped if it is operated at speeds below 20 Hz for more than 5 minutes.
Depending on the operating pressure, the empirical value for the supplied sealing gas
amount is between 1% (for a high operating pressure) and 8% (for a lower operating
pressure) of the effective suction capacity. The set quantity of sealing gas influences the
effective suction capacity and the achievable ultimate pressure.
Open gas cylinder 325.
Set a maximum pressure of 2.5 bar at pressure reducer 324.
At dosing valve 315, adjust the desired quantity of sealing gas on the flow meter.

NOTICE
High pressure in the sealing gas line when the pump is switched off!
Risk of damage to the pump seals.
Lower sealing gas pressure to < 1200 hPa or stop sealing gas feed immediately.
Set max. flushing quantity in acc. with the following table; use flow meter.
– On pumping stations without an intermediate condenser or collecting containers
the quantity of fluid should be selected according to the smallest pump in the pumping station:
Pump type max. flushing quantity
Okta 18000 3 l/min
Okta 8000 2 l/min
Okta 6000 1.75 l/min
Okta 4000 1.5 l/min
Okta 2000 1.0 l/min
Okta 1000 0.5 l/min
Okta 250/500 0.25 l/min
Okta 300/600 0,25 l/min
High pressures are generated in the working chamber of the pump!
Exceeding the specified flushing quantities can lead to destruction of the pump.
Do not exceed the indicated flushing quantity at 3000 hPa in the indicated time peri-
od.
Drain the fluid again.
Always check the vapour compatibility of the downstream pumps.
Dry the pump completely inside after flushing.
6.3 Switching off and venting
In the case of clean processes that convey pure gases, the pump can be switched off in
every pressure range and directly after the process end. When the evacuated medium
in the suction chamber causes strong contamination or deposits, the vacuum pump
should be flushed with air or nitrogen after the process end.
If venting of the vacuum chamber is not required, then the intake port valve must be
closed before switching off the pump in order to prevent venting of the vacuum chamber.
NOTICE
21
Operation
WARNING
Exposed, rotating rotors!
Danger of crushing! The rotors will continue to run under vacuum after the motor has
been switched off.
Never disconnect any pipe connections at the vacuum flange or fore-vacuum flange
or any sealing gas lines while the pump is running.
NOTICE
High pressure in the sealing gas line when the pump is switched off!
Risk of damage to the pump seals.
Lower sealing gas pressure to < 1200 hPa or stop sealing gas feed immediately.
Flush pump with
flushing gas
Close shut-off valve in the intake line and separate the pump from the process.
Open flushing gas feed at the intake flange.
Pump is operated for an additional 20 to 40 minutes while flushing gas is suctioned in.
Close sealing gas valve.
Switch off the pump.
Venting should be performed via the suction side, do not ventilate vacuum chambers
through the pump.
Stop flushing gas feed.
Switching back on After switching off the pump it can be switched back on again within 5 minutes. If you wait
any longer then leave the pump to cool to ambient temperature before switching back on
again.
NOTICE
Roots pump damage due to the rotors starting up!
Differences in the rate of cooling of the pump housing and rotors can cause damage to
the pump.
If the pump / pumping station is switched off and at a standstill for > 5 minutes, then
only switch it on again after ventilation and a waiting period of at least 120 minutes to
allow a balanced temperature of rotors and housing.

7.2 Changing the lubricant
WARNING
Hot operating fluid!
Danger of burns when draining due to contact with skin.
Wear suitable protective clothing.
Use a suitable collecting vessel.
Depending on the applications, Pfeiffer Vacuum recommends determining the exact service life of the operating fluid during the first year of operation.
The replacement interval may vary from the guide value specified by Pfeiffer Vacuum
depending on the thermal and chemical loads, and the accumulation of suspended particles and condensation in the operating fluid.
Gear chamber The intervals for replacing lubricant in the gear and bearing chambers are heavily depen-
dent upon the operating conditions.
Change the lubricant at least once every year.
Turn off the vacuum pump, vent to atmospheric pressure and allow to cool.
Unscrew lubricant filler screws 15.
Unscrew the lubricant drain screws 16 and drain the lubricant; pay attention to the O-
rings!

Maintenance
Change sealing oil
(only for version with
RSSR)
Changing the sealant
of the mechanical
seal
It is recommended that the sealing oil should be changed on an annual basis.
Unscrew lubricant drain screw 16.1 at the sealing oil chamber; check the O-ring.
Allow the lubricant to drain off.
Screw in lubricant drain screw 16.1 with O-ring.
Fill oiler 18 to halfway with new lubricant (sealing oil).
Falling oil level in the oiler and an oil leak below the lamp indicates a defective external
radial shaft seal ring. In this case, the pump can continue to operate for a certain time
provided the oil loss from the oiler is equalised.
Conversely, an increasing oil level without visible loss below the pump indicates a worn
internal radial shaft seal ring. All three sealing rings should be replaced immediately as
it will cause the oil in the bearing chamber to rise above the permitted level.
Maintenance work on the mechanical seal and the sealant reservoir should be per-
formed in accordance with the maintenance instructions supplied by the manufacturer; the intervals for changing the sealant may vary from application to application.
Use the sealant in accordance with the manufacturer's instructions.
7.3 Cleaning the suction chamber
Exposed, rotating rolling pistons!
Fingers and hands can become crushed when the intake flange is open.
Keep all body parts out of operating range of the rolling pistons.
Use a wooden handle to rotate the rolling pistons during cleaning.
WARNING
NOTICE
Risk of damage to the pump!
During the flushing and cleaning procedure the flushing liquid and the process medium
can pass over into the bearings and oil chambers and can stick there.
To protect the bearings during cleaning, sealing gas must always be used.
Disconnect the drive motor from the mains and secure it so that it cannot be switched
on.
Dismantle the vacuum line and the fore-vacuum line of the pump.
