Introduction
1.2 Description
Refer to Figure 1. The HV8000 pumps are positive displacement pumps. They must be used with a suitable backing
pump or pumps: refer to Table 2.
The HV8000 pumps are available in two versions:
'VF' (Vertical Flow) pumps which provide for a vertical gas flow through the pump.
'HF' (Horizontal Flow) pumps which provide for a horizontal gas flow through the pump.
The HV8000 pumps can be supplied in 'bareshaft' form without any motor or fitted with a 18.5 kW IEC motor.
HV8000 VF and HF pumps with motors are supplied with the motor mounted via a bell-housing and connected through
a direct drive coupling: refer to Figure 3 and 5.
If your pump is supplied as a bareshaft pump, you may connect your own coupling or belt drive system (refer to
Section 3.7) to the drive shaft of the pump in order to operate the pump. The maximum power rating and maximum
pump speed must not exceed the values shown in Table 2.
Alternately, two motor mounting kits are available to enable customers to fit their own motors. The first kit is
suitable for use with motors to an IEC specification not exceeding 18.5 kW with a 160 Frame size and FF300 flange.
The second kit is suitable for use with motors to a NEMA specification not exceeding 25 hp with a 284TS Frame size
and a D type flange. These kits include the appropriate bell-housing, coupling and fixings.
For specific applications, bareshaft pumps may be fitted with motors of higher power ratings than those given above
and controlled through a Variable Frequency Drive (VFD). Customers must consult with Edwards Applications Group
for information relating to such applications.
Refer to Section 2.11 for the Item Numbers of the different pump versions.
1.3 Principle of operation
Refer to Figure 1. The HV8000 pumps are positive displacement pumps, which incorporate two contra-rotating twin-
lobe rotors:
One of the rotors is driven by the drive shaft (18).
The other rotor is maintained in the correct phase relation by timing gears.
During operation, the inlet gas stream to be pumped enters the pump at the inlet (4).
As the two contra-rotating rotors turn, the inlet gas is trapped in the chambers which form between the rotors and
the pump-body, and is eventually forced out of the pump at the outlet (14).
The timing gears and the bearings on the rotors and drive shaft are lubricated by oil in the drive end cover (7) and
the non-drive end cover (17).
The mechanical shaft seals and the external lip seals are provided with oil from the shaft-seals oil reservoir (5). This
provides a barrier seal between the compression chamber (rotor housing) and the external atmosphere.

1.4 Application
The safe area HV8000 pumps are safe to handle non-flammable gases and vapours within the normal operating
parameters of the pumps, as defined in this manual.
The materials of construction of the pumps are specified in Section 2.10. Before you use the pump, you must ensure
that these materials are compatible with the gases and vapours which you will pump or which may exist in the
external atmosphere.
You must ensure that your pump is suitable for your application. If you have any doubts as to the suitability of the
pump for your application, contact your supplier or Edwards for advice.
1.5 Normal operation
In normal operation, as defined by this manual, the boosters are safe for the pumping of non flammable materials
where there is no risk that the build-up of process deposits could reduce the operating clearances of the pump
mechanism and so cause damage.
A mesh screen is provided as standard on the inlet side of the pump. This should remain in place during installation
and commissioning to reduce the risk of damage owing to the ingress of gross debris.
The inlet screen must be left in place during normal process operation although it will reduce the pumping speed of
the pump by about 15%.
1.6 Abnormal operation
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, explosive dust atmospheres.
Use in ambient conditions other than those specified in Section 2.1.
WARNING
A booster must always be used in conjunction with a backing pump - never attempt to operate it
alone.
WARNING
The booster pumps have dry pump mechanisms that are designed to run with small clearances
between rotors and stator. You must protect your pump from the ingress of dust or particles that
could cause damage.
WARNING
Misuse of the booster as described below is strictly prohibited.

2.1 Operating and storage conditions
Note: For operation between -20 °C and 5 °C (-4 and 41 °F), we recommend that the HV8000 pump is operated
continuously except when shut-down is necessary for maintenance purposes. Note also the cooling-water
requirements given in Section 2.4.
There is a wide range of backing pumps which are suitable for use with the HV8000 pumps. If necessary,
contact Edwards for advice.
