Edwards RV3 Vacuum Pump, Edwards (CAT#: STEM-GLE-0632-LGZ)

The manufacturer of Edwards RV3 Vacuum Pump is Edwards. Model is RV3. The Edwards RV3 two-stage rotary vane mechanical vacuum pump has a peak pump speed of 2.6 cfm at 60hz, and 1.5x10-3 Torr (2x10-3 mbar) is his ultimate pressure. The Edwards RV3 has a maximum steam inlet pressure of 60 Torr and a maximum water vapor capacity of 220 g/hr. Relatively light at just 47 pounds and measuring 16.9 inches long, 6.2 inches wide, and 8.9 inches high, the Edwards RV3 is light and transportable. This vacuum pump uses ultragade 19 as the oil type and the oil capacity is 0.70 liters. The RV3 still works in temperatures as low as 12 degrees Celsius to 40 degrees Celsius. The noise during operation is very low, only 48 dB(a). The specification of the pump is 115V, and it can also be 230V.

High reliability: generous lubrication of moving parts.
Safe process and systems: fast acting inlet valve for best in class anti suck back protection.
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.
