WMPA SERIES SEAL-LESS ROTARY VANE PUMPS

B) DO NOT DEAD-HEAD THE PUMP! In general, the inlet and discharge lines should not be restricted any more than necessary. Restricting the suction line may lead to cavitation, or if compaletely blocked, a dry run. Restricting the discharge pipe may overload the motor (a rotary vane pump requires more power with increasing head.)

Rotary Vane Pumps McMaster-Carr

Commonly called rotary vane pumps, they have a built-in bypass relief valve to prevent pressure buildup. Attach an electric motor with a speed reducer or a belt pulley to alter the pump speed. Use a NEMA 56C frame motor. Pumps are gravity fed and require an elevated liquid source to fully fill the pump before turning on. Do not run dry or use with solids.

Aitcool ARV-8 Rotary Vane Pump Vaccuum Pump - BHO

Rotary vane - also known as sliding vane pumps - are designed to pump for extended periods of time and are renowned for their ability to pull down to a deep vacuum. They are extremely reliable and work via a positive displacement principle, essentially trapping the fluid/vapour as it is pulled into the inlet pipe, trapping it in-between the vanes on the inside cam and forcing it through the ...
