The Edwards RV12 rotary vane vacuum pump features a two-position gas ballast which provides either 60 g/hr or a 290 g/hr water vapor handling capacity. A unique mode selector switch allows the pump to be used for both high throughput and high vacuum applications. This pump comes with a universal motor which works across a wide range of voltage and frequency. The motor features an external switch to shift from high to low voltage range. A fast-acting inlet valve ensures best in class anti-suck back protection. The valve closes rapidly within 0.4 seconds of pump stopping. The valve opens smoothly using oil pressure to prevent pressure surges. The pump comes with an inlet seal and integrated inlet mesh filter.

The Edwards RV12 has a peak pumping speed of 8.4 cfm at 60 Hz, an ultimate pressure of 2 x 10-3 mbar / 1.5 x 10-3 Torr and a maximum inlet pressure for water vapor of 32 mbar / 24 Torr. It has a maximum oil capacity of 1 liter and uses Ultragrade 19 oil. The Ultragrade 19 oil is designed to provide optimal vacuum performance and longer pump life. The RV12 provides a quiet operation with a noise level of 48 dBA at 50Hz. An operating temperature range of 12 to 40 °C provides flexibility to use this pump across varying conditions. The pump is externally approved to UL and CSA standards. A lifting bracket is fitted to the pump, which can be used with lifting equipment for easy movement of the pump.
