RV3 PFPE

Edwards RV pumps have become the industry standard for scientific primary pumping applications. RV pumps are uniquely capable of delivering high or low throughputs with high ultimate vacuum. This, combined with ultra-low noise levels, makes them ideal for a wide range of applications including GCMS and other small bench top type applications.

Features and Benefits

  • 48 dB(A) and intrusive frequencies minimised.
  • Dual mode. Suitable for high throughput and high vacuum applications.
  • Easy-to-use gas ballast.
  • Fast acting inlet valve for system protection.
  • High torque, dual voltage/dual frequency motor, electronic start relay.
  • Efficient high pressure lubrication.
  • Oil-tight with printed gaskets, effective shaft seals.
  • Clamped-in sight glass.
  • Hi-tech polymer blades, large diameter, easy-clean oil passages.
  • Consistent, built-in quality, cast bar construction.
