Edwards RV8 Vacuum Pump, Edwards (CAT#: STEM-GLE-0634-LGZ)

The manufacturer of Edwards RV8 Vacuum Pump is Edwards. Model is RV8. The Edwards RV8 rotary vane vacuum pump has a peak pump speed of 6cfm at 60hz and 1.5x10-3 Torr (2x10-3 mbar) is his ultimate pressure. With a small footprint and relatively light weight at just 57 pounds, this vacuum pump is an ideal addition to any laboratory, of all sizes, and can be utilized in almost any application. With an extremely low noise level of 48 decibels, this vacuum pump is quiet enough to keep potential damage to a minimum. The Edwards RV8 has a maximum water vapor inlet pressure of 38 Torr and a maximum water vapor capacity II of 220 g/hr. The operating range of the RV8 is between 12 °C and 40 °C. The oil type of ultragade 19 was adopted with a total oil capacity of 0.75 liters and a minimum oil capacity of 0.43 liters. The specification of the pump is 115V, and it can also be 230 V.

Configured to meet your vacuum needs: mode selector and two position gas ballast.
No unplanned downtime: designed for easy maintenance.
Better work environment: quiet running and intrusive frequencies minimised.
Two position gas ballast: allows either 60 g/hr or a class leading 220 g/hr of water vapour to be handled.
Universal motor: to cover the widest possible voltage and frequency range from a single variant.
Smooth controlled inlet valve: opening by oil pressure to eliminate pressure surges.
Rapid closing inlet valve: within 0.4 seconds of pump stopping.

1. Huge final vacuum pressure, capable of high pumping speed and superior steam handling.
2. It is quiet during operation.
