Function
The pumps of the
TOPAS D004 V - D041 V
series are oil flooded rotary vane
vacuum pumps. You have an oil mist filter on the outlet side. The motor ventila-
tor provides cooling for the motor and pump housing. The motor and pump have
a common shaft.
When necessary, a vacuum regulating valve, additional check valve, vacuum-tight
suction filter, fluid separator, tube connection and motor circuit breaker.
The suctioned medium (air) flows through the suction filter (optional). The medi-
um fills the suction area of the pump (1). Through rotation of the rotor, the slid-
ers are pushed through centrifugal force against the internal wall of the housing,
thus forming three chambers with a consequence of different volumes, which
permit the generation of an underpressure and a flow rate.
The medium is de-oiled by the filter element and then flows out of the pump. An
oil back-suction sucks the oil separated through the filter element back into the
pump body.
