Oil-lubricated rotary vane vacuum pumps are positive-displacement pumps that feature sliding vanes in a rotor rotating within a cavity. An eccentrically mounted rotor with slots rotates in a cylindrical housing and the precisely fitting sliding vanes move in the slots and separate the individual working chambers.

Almost all distillation and drying applications have a common problem that lot of condensable vapor enters into pump and contaminates the oil. If oil is not changed then vacuum level deteriorates & also damage internal parts.

Chemical series vacuum pump is designed to handle higher amount of condensable vapor. It achieves high vacuum upto 10″ Torr at suction port of vacuum pump. If higher vacuum is required then we offer combination of Rotary Vane Pump and Roots Pump.
