approved by us before the pump is started.
2. General description
2.1. Vacuum and flow rate
A vacuum is a pressure in a system that is less than the ambient atmospheric
pressure. It can be shown in absolute terms or in effective gauge terms:
▪ mbar(a) - the absolute pressure shows how much the pressure is above the
absolute zero vacuum.
▪ (minus) mbar(e) - the effective or gauge pressure shows how much the
pressure is below the local atmospheric pressure.
2.2. Introduction
The pumps are single‑stage, oil‑sealed screw pumps driven by an electric motor.
The pumps are controlled by our controller.
The controller is attached to the front door. An electric cabinet is installed behind
the front door. The electric cabinet contains fuses, transformers, relays, etc.
The pumps use Variable Speed Drive (VSD) technology. The VSD technology
helps to automatically adjust the motor speed as necessary.
The pumps are available as air‑cooled and water‑cooled. The pumps have a
sound‑insulated canopy.
Air flow
Air comes in through the air intake filter and the control valve and is displaced by
the pump element. A mixture of air and oil flows into the oil separator tank. After
passing the air/oil separator filter, clean air, conditioned to a few parts per million,
is released through the outlet.
Oil system
The oil separator tank removes most of the oil from the air/oil mixture by the
centrifugal action. The oil separator removes the remaining oil. The oil collects in
the lower part of the oil separator tank.
The oil system has a thermostatic bypass valve. When the oil temperature is less
than 83 °C (181 °F) (87 °C (189 °F) for optional high‑water handling capacity
versions), the bypass valve stops the oil supply from the oil cooler.
The air pressure pushes the oil from the oil separator tank through the oil filter.
The oil cooler is bypassed. When the oil temperature increases up to 83 °C
(181 °F) (87 °C (189 °F) for the optional high‑water handling capacity versions),
the thermostatic bypass valve starts the supply from the oil cooler. At
approximately 95 °C (203 °F) (104 °C (219 °F) for the optional high‑water
handling capacity versions), all the oil flows through the oil cooler. The filtered oil
flows into the pump element.
Cooling
The cooling system has an oil cooler.
The fan blows air over the coolers. The fan is set to on or off, depending on the
operating conditions, as per the specific algorithm.
1. Drain point
Turbo version
The regulation system of the turbo version can handle fast cycling duties. When
the vacuum pressure reaches the set‑point, the regulator will keep the motor
operating at increased speed for an adjustable time before the regulator
decreases the motor speed.
Electrical diagrams
You can find the electrical diagram in the electric cabinet.

▪ Add 10% to the total pump current (Itot from the tables) and divide by 2
▪ Multiply the ampacity of the cables with 0.8 (refer to table A.52.17
(52‑E1))
▪ Install fuses of half the size of the recommended maximum fuse size on
each cable.
▪ When using 2 x 3 phases + PE as in (3):
▪ Add 10% to the total pump current (Itot from the tables) and divide by √3
▪ Multiply the ampacity of the cables with 0.8 (refer to table A.52.17
(52‑E1))
▪ Fuse size: the recommended maximum fuse size divided by √3 on each
cable.
▪ Size of the PE cable:
▪ For supply cables up to 35 mm²: same size as supply cables
▪ For supply cables larger than 35 mm²: half the size of the supply wires
▪ Always check the voltage drop over the cable (less than 5% of the
nominal voltage is recommended).
▪ Example: Itot= 89 A, maximum ambient temperature is 45 °C,
recommended fuse = 100 A
▪ Single supply cables (3 phases + PE - configuration (1)):
▪ I = 89 A + 10% = 89 x 1.1 = 97.9 A
▪ The table for B2 and ambient temperature = 45 °C permits a maximum
current of 93 A for a 50 mm² cable. For a cable of 70 mm², the maximum
permitted current is 118 A, which is sufficient. Use a 3 x 70 mm² + 35 mm²
cable.
If method C is used, 50 mm² is sufficient. (35 mm² for method F) =>cable
3 x 50 mm² + 25 mm².
▪ Parallel supply cable (2 x 3 phases + PE - configuration (2)):
▪ I = (89 A + 10%)/2 = (89 x 1.1)/2 = 49 A
▪ For a cable of 25 mm², B2 at 45 °C, the maximum current is
63 A x 0.8 = 50.4 A. So, 2 parallel cables of 3 x 25 mm² + 25 mm² are
sufficient.
▪ Install 50 A fuses on each cable instead of 100 A.
Note:
In open circuit cooling towers, take applicable protective measures to prevent
the growth of harmful bacteria (for example, legionella pneumophila) because
of the risk of inhalation of the water droplets.
The recommended cooling water temperature is 20~25 °C, considering
cooling efficiency and condensation on the surface.
We recommend that you install isolation valves at the cooling water inlet and
outlet to isolate the pump from the piping system before you do the maintenance.
Isolate the cooling water pipes when the pump is not running or on standby for a
long time to prevent the risk of condensation damage on water/oil cooler
surfaces.
Note:
Make sure that the isolation valve opens when the pump is running to prevent
the damage of water/oil cooler.
General recommendations cannot include all combinations of the various
compounds, solids and gases that are in the cooling water (in interaction with the
different materials). The recommendations given in the cooling water
specifications are a general guideline for the permitted coolant quality. A
statement is given in the specification where strict limits are necessary.
The water requirements are applicable for untreated water. When the water is
treated some parameters will change.
Water treatments should be done by a specialized water treatment company
(taking responsibility for the performance of the treated cooling water and the
compatibility with the materials in the cooling circuit). This includes:
▪ selection of the correct additives
▪ selection of the correct application
▪ monitoring the concentrations and properties
▪ preventing the formation of sludge

A. Isolation valve
Note:
A sufficient space is necessary (1 m of clearance on all sides and top of the
pump) for the safe and correct installation, daily inspection and maintenance.
6.3. Piping
The vacuum distribution and piping system, including the pump and all related
components, must be designed in accordance with generally accepted
engineering practices. For example, inlet pipe work should slope away from the
pump. Incorrectly designed distribution systems can cause the damage to the
pump. Exhaust pipes should be installed in such a way that they do not create
additional back pressure on the pump.
The exhaust pipes should be installed sloping away from the pump.
A drip leg with a drain point provision is given in the pump to prevent the
condensate to go back into the fluid reservoir.
Take precautions to prevent the installation of the pipes in a strain with the pump.
Use sufficient pipe diameter for the vacuum network. The combination of
restrictive pipe diameter and long pipes can create a pressure drop. For the
single pump installation, keep the diameter of the pump inlet as far into the
process as possible.
We recommend to install an isolation valve at the inlet of the pump to isolate the
pump from vacuum distribution and piping system before you do the
maintenance.
The discharge air can have temperature up to 120 °C (248 °F), make sure that
the pipes can take this temperature.
The external force extended on the inlet connection is limited to 200 kg. The
external force extended on the outlet connection is limited to 50 kg. The
connection pipes must be free from strain.
The pump has an inlet filter. But related to the application, an additional inlet
filtration upfront the pump can be necessary.
We recommended to install an isolation valve at inlet and outlet of the air and
water pipes to isolate the pump from the vacuum distribution and piping system
before you do the maintenance.
Remove the dust caps from the cooling water inlet and outlet. Connect the water
hoses to the water inlet and outlet ports. Check the water hoses, pipelines and
connections that there are no leaks.
6.4. Ventilation
Install the inlet grids and the ventilation fan to prevent the recirculation of the
cooling air to the inlet grating of the pump. The air velocity to the grids must not
be more than 5 m/s.
The maximum air temperature at the intake opening for 3 ph is 46 °C (115 °F)
and for 1 ph is 32 °C (90 °F), (minimum 0 °C / 32 °F).
Refer to for ventilation alternatives.
The ventilation alternative 1 and 3:
The necessary ventilation to limit the pump room temperature is calculated from:
Qv = SF * Pnom / (1.21 * dT)
Where,
Qv = necessary cooling air flow (m³/s)
SF= Service factor of motor
Pnom = Nominal motor power of the pump (kW)
dT= Temperature increase in the pump room (°C)
Ventilation alternative 2 and 4:
The fan capacity should match the pump-fan capacity at a pressure head equal
to the pressure drop caused by cooling air ducts.
Maximum permitted pressure drop in ducting before or after the pump = 10 Pa.
Outdoor/altitude operation
The pumps are designed according to the IP2X classification. The electrical
cabinet and motor are designed according to the IP54 classification. If the pump
is installed outdoors, special precautions must be taken. Contact us.
The pumps can only be used in temperatures above 0 °C (+32 °F). If frost
occurs, take applicable protective steps to prevent damage to the pump and its
ancillary equipment. In this case, contact us.
If it is necessary to operate the pump at more than 1000 m (3300 ft), contact us.
▪ Use correct lifting equipment (fork-lift truck or pallet truck) to move the pump
on its pallet, near to the installation area.
▪ The pumps can be moved by a lift truck using the slots in the frame.
▪ Lift the pump vertically.
▪ Carefully lift the pump without twisting.
▪ Before lifting, install the transport securing bolts.
▪ Make sure that the forks extend to the other side of the frame.
▪ The pumps can also be lifted after you insert beams in the slots.
▪ Make sure that the beams do not slide and extend uniformly from the frame.
▪ Hold the chains parallel to the bodywork by the chain spreaders to prevent
damage to the pump.
6.6. Acclimatization
When you move the pump to the installation room, condensation can occur on
some components. Make sure that the pump is left idle for minimum 2 hours to
adjust in the installation room condition.
Most pumps are designed for use in TT/TN networks and are intended for an
industrial environment where the electrical supply is separated from the
residential/commercial supply network.
To use the pump in light industrial, commercial or residential environments with a
shared supply network, or in an IT network, extra precautions are necessary.
Contact us for information.
Note:
You can find the correct position for the electrical connection on the dimension
drawings.
A correct cable gland must be used when the supply cable is connected to the
pump. This will give the necessary protection to the electrical cubicle and its
components from dust.
1. Install an isolating switch.
2. Check that the motor cables and wires in the electric cabinet are connected to
their terminals.
3. Check the fuses. Refer to Electrical cable size on page 44.
4. Connect the power supply cables to the terminals (1, 3 and 5).
5. Connect the earth conductor to the earth bolt.
Note:
Modifications must be approved by us.
Stop the pump and switch off the voltage before external equipment is
connected.
Only potential‑free contacts are permitted.

4. Make sure that the electrical connections correspond to the local codes and
that all wires are clamped tight to their terminals.
5. The installation must be earthed and protected against short circuits by fuses
of the inert type in all phases. Install an isolating switch near the pump.
6. If electrical connections of motor, fan or converter have been disconnected,
always check the rotation direction.
7. Check that the process lines are of correct size to prevent high pressure drop
and for cleanliness to protect the pump. Also check for leaks.
8. Make sure that the pump outlet is not blocked.
9. Install the inlet isolation valve. Refer to Installation on page 61 for the position
of the valve.
10. Close the valve.
11. Connect the inlet pipework to the valve.
12. Check the oil level. The oil level must reach the top of the oil sight glass.
13. If necessary, fill the oil through the oil filler plug.
14. Make sure that no dirt enters the oil system.
Note:
When the automatic operation LED is on, the pump can start automatically.
When the automatic operation LED is on, the controller controls the pump, for
example, to load, stop and restart the motors.
Regularly check the oil level during the operation.
A few minutes after the pump is stopped the oil level should touch the top of the
oil sight glass.
If the oil level is too low:
1. Wait until the pump has vented.
