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.
