Edwards GVSP30 Dry Scroll Vacuum Pump
If you want to pump condensable vapours, or if you
will regularly use the GVSP30 to pump down from
atmospheric pressure in a humid environment (for
example, if relative humidity exceeds 60%), you
must use gas ballast (refer to Section 3.10).
Inlet gas temperatures should not exceed 50 oC. If
you need to pump gases above this temperature,
install a chiller in the foreline, otherwise premature
failure of the pump may occur.
The body of the pump includes stationary scrolls (5)
and an orbiting scroll. The orbiting scroll is driven by
the electric motor through an eccentric cam on the
motor drive shaft. The movement of the orbiting
scroll, meshed with the stationary scrolls, forms
successive crescent shaped volumes in the pump.
Gas which enters the pump through the inlet (2) is
compressed by the movement of the orbiting scroll
and swept towards the centre of the stationary
scrolls. The compressed gas enters the exhaust port
near the centre of the stationary scrolls and is
exhausted from the pump through the outlet (4).
The pump inlet (2) has an inlet screen which
prevents the entry of debris into the pump.
The pump is air-cooled and has an electric motor
and an hours counter (14) which operates when the
electrical supply to the pump is switched on.
