Oil sealed rotary vane vacuum pumps


Hot and cold temperature operation

The permitted ambient temperature operating range of an oil sealed rotary vane vacuum pumps is generally 5 to 40oC.  Operating outside of this range can cause lubrication failure and major damage to the pump. 

For cold temperatures ensure that the correct oil/viscosity is used and for temperaturesless then 5oC you must either use an approved synthetic oil or alternatively install a thermostatically controlled oil sump heater.

For ambient's over 40oC, increase plant space ventilation, reduce the oil change interval, use an approved synthetic oil or in come cases you can consider water cooling.

When using single phase motored models, ensure that you allow 10 seconds between switching the pump, as frequent switching will damage the start capacitor.
