product description

Compared with other oil-sealed rotary vane pumps, RV series oil-sealed rotary vane pumps have lower operating and maintenance costs. This design feature has made them the standard oil-sealed rotary vane pump in the laboratory application industry for many years. Meets UL and CSA standards. Edwards has a global network, and all pump products in the world have been inspected by external testing agencies to provide support for product applications and services.

 

Features of EDWARDS vacuum pump RV3:

(1) The vacuum pump has a large pumping speed in a wide pressure range;

(2) No oil sealing and lubrication is required in the pump chamber, which can reduce the pollution of oil vapor to the vacuum system;

(3) Vacuum pump There is no compression in the cavity and no exhaust valve. The structure is simple and compact, and it is not sensitive to dust and water vapor in the pumped gas;

(4) The rotor has good geometric symmetry, so the vibration is small and the operation is smooth. There are gaps between the rotors and between the rotor and the shell, and no lubrication is required. , the friction loss is small, which can greatly reduce the driving power, thus achieving higher speed;
