1.2 Description
The RUVAC WA 40000 Vacuum Booster Pump is a large direct drive mechanical booster pump with
a nominal capacity of 44300m3h-1 @ 66Hz (40000 m3h-1 @ 60Hz). It is designed to operate reliably
for long periods with minimal requirements for maintenance.
The RUVAC WA 40000 is intended for use in large capacity vacuum pumping systems. It must be
backed by suitable backing pump(s): It is not suitable for use without such backing pumps.

1.3 Application
The RUVAC WA 40000 is safe to handle non-flammable gases and vapours within the normal
operating parameters of the pumps as defined in this manual. The standard version of the RUVAC
WA 40000 (covered by this manual) is not suitable for hazardous area installation. For this kind of
application, please consult application specialists from your supplier or your local sales
representative who can assist on product selection.
The materials of construction are specified in Section 2.10. Before using the pump, ensure that
these materials are compatible with the gases and vapours which will be pumped or which may exist
in the external atmosphere.
Ensure that the pump is suitable for the application. If there are doubts as to the suitability of the
pump, contact your supplier or your local sales representative for advice.
1.4 Normal operation
WARNING
A booster must always be used in conjunction with a backing pump. Never
attempt to operate it alone.
WARNING
Booster pumps have dry pumping mechanisms that are designed to run with small
clearances between the rotors and stators. It is recommended that an inlet screen
is fitted to protect the pump from ingress of dust or larger particles that could
cause damage.
WARNING
The pump is intended for generating a vacuum only. For example, if an
overpressure occurs in the pump, the system must be protected by an
overpressure safety valve.

1.5 Abnormal operation
WARNING
The pump is not allowed to run faster than the defined maximum rotational speed
at any time. (Refer to the Section 2.3).
WARNING
Misuse of the booster as described below is strictly prohibited.
 Pumping flammable gases.
 Pumping hydrocarbon oxides.
 Pumping pyrophoric gases.
 Pumping gases that tend to self-decompose, or that are chemically unstable.
 Pumping peroxides or oxygen enriched atmospheres.
 Pumping of, or use in the presence of, dust atmospheres both inert and explosive.
 Use in ambient conditions other than those specified in Section 2.1.
 Use of the RUVAC WA 40000 booster in excess of the limits defined in this manual.
 Gas shock loads such as rapid opening of the foreline inlet against atmospheric pressure.

2.1 Operating and storage conditions
Note:
For operation between -20 °C and 5 °C (-4 and 41 °F), we recommend that the RUVAC WA 40000
pump is operated
continuously except when shutdown is necessary for maintenance purposes. Note
also the cooling water requirements given in Section 2.4.
Adequate thermal protection against overheating is recommended, RUVAC WA 40000 is provided
with a PT100 probe for measuring exhaust gas temperature, contact local sales representative for
advice.
The RUVAC WA 40000 bare shaft pumps are designed to be functional at altitude up to 3000 m.
Whereas motors are derated if the altitude exceeds 1000 m above sea level, contact local sales
representative for advice.
There is a wide range of backing pumps which are suitable for use with the RUVAC WA 40000 pumps.
If necessary, contact your local sales representative for advice.

WARNING
If an isolation valve is fitted between the RUVAC WA 40000 pump and the
backing pump, interlock the operation of the valve with the operation of the
RUVAC WA 40000 pump, so that closure of the valve results in shutdown of the
RUVAC WA 40000 pump.

3 Installation
CAUTION
Liability or warranty claims will not be accepted if the installation includes any modifications or
additions to the pump without the prior written approval, or if the pump is incorrectly installed.
3.1 Installation safety
WARNING
Obey the safety instructions listed below and take note of appropriate precautions
while installing the pump. Failure to follow the instructions can cause injury to
people and damage to equipment.
 Only a trained and competent engineer may carry out the installation of the
RUVAC WA 40000 pump. For advice contact your local customer centre.
 Disconnect the other components in the pumping system from the electrical supply so that
they cannot be operated accidentally.
 Ensure that the cooling air flow through the pump motor cooling fan cannot be obstructed.
 Ensure that all electrical cables, purge gas pipelines and cooling water pipelines are safely
positioned, secured and routed, so that they do not present a trip hazard.
 Leak test the system after installation work is complete and seal any leaks found to prevent
leakage of hazardous substances out of the system and leakage of air into the system.
3.2 Unpack and inspect
WARNING
Use suitable lifting equipment to move the pump. Failure to follow the instructions
can cause injury to people or damage the pump. Refer to section 2.5 for the mass
of the pump.
1. Use a suitable fork lift truck or pallet truck to move the pump, on its pallet, close to the place of
installation.
2. Remove all packing materials.
3. Use suitable lifting gear to remove the RUVAC WA 40000 pump from its pallet.
4. Ensure the sling centre is in line with centre of gravity which is indicated on Figure 2 and Figure 3
Refer to Figure 4.

3.3 Mechanical installation
3.3.1 Locate the pump
WARNING
Use suitable lifting equipment to move the pump. Failure to follow the instruction
can cause injury or can damage the pump. Refer to Section 2.5 for the mass of
the pump.
Ensure that when the pump is in its required operating location, all of the mounting feet (on the
pump or base frame) are flat on the mounting platform to within 0.2 mm m-1 (0.0026-inch ft-1).
Use the following procedure to locate the RUVAC WA 40000 pump:
1. Use suitable lifting equipment to move the RUVAC WA 40000 pump into its required operating
location: use the appropriate method for the pump, as described in Section 3.2.
2. Fit suitable bolts through the fixing holes in the mounting feet, to secure the pump in position.
Refer to Figure 2 for fixing details.
3. Disconnect the lifting equipment from the pump.
3.3.2 Motor installation for bareshaft variant
 Choose an appropriate motor to be installed onto RUVAC WA 40000 according to related
mechanical parts size. Refer to Figure 5 for mechanical parts size.
