Pump ranges
These operating instructions concern the following oil flooded rotary vane vacuum pumps: VGD 10 and VGD 15.
The vacuum capacities at atmosphere are 10 and 15 m
against vacuum can be seen in the data sheet D 230.
Description
VGD vacuum pump is fitted with a mesh filter on the pump inlet. On the exhaust side of the pump an oil mist eliminator
is fitted which has the function of re-circulating oil back into the circulation system as well as providing high efficiency
separation on the pump exhaust. The motor fan cools both the motor and the pump housing. Both the motor and pump
have a common shaft.
A standard built-in non-return valve on the inlet of the pump, seals the pump from the process when the pump is stopped.
This prevents oil moving into the pumping cylinder when the pump is stationary. Excessive oil in the cylinder could cause
an hydraulic lock when the pump is started and hence undue stress on the rotor blades.
The gas ballast valve ((U) ➝ optional extra) avoids any condensation of a small amount of water vapour inside the pump
and hence emulsification of the oil.
Optional extras: hose connection (ZSA), motor starter (ZMS), gas ballast valve and metal cover (see picture
