These vacuum pumps offer a suction capacity of 10, 15 and 20 cum/h. The vacuum lubrication and oil recirculation is able to be adjusted via an oiler which is situated near the suction inlet. Supported by independent bearings which are housed in the two pump flanges, the rotor is cantilevered-fitted on the motor shaft.
The pump is surface cooled and heat is dispersed from the outer surface, which is appropriately finned, by way of a radial fan which is situated between the pump and motor. Installed on the pump exhaust is an oil recovery tank which contains a separator filter used to reduce noise and prevents oil mist. It is highly recommended to install a filter and check valve on the suction inlet. Single-phase electric motors can be supplied with this range of pumps.
