EDWARDS RV3 vacuum pump bipolar selector vane vacuum pumps


DEWA EDWARDS VACUUM PUMP RV3 Features (1) The vacuum pump has a large pumping speed in a wide pressure range; (2) No need for oil sealing and lubrication in the pump chamber reduces the contamination of oil vapor on the vacuum system; (3) No compression in the vacuum pump chamber, no exhaust valve. The structure is simple, compact, and insensitive to dust and water vapor in the pumped gas; (4) The rotor has good geometric symmetry, so it has little vibration and smooth operation. There are gaps between the rotor and between the rotor and the shell, without lubrication, small friction loss, which can greatly reduce the driving power, so that a higher speed can be realized.
