The QS5 Vacuum Pump is a two-stage, rotary vane pump with 5-cfm rated displacement for ultimate vacuum down to 15 microns. It is designed for quick, deep evacuation, as well as affordability and ...

A rotary-vane pump's electric motor cannot efficiently cycle on and off to break a vacuum. A vacuum valve can be added for intermittent use, but the motor must still run continuously.

He developed the technology for both vacuum pump and compressor applications. Compared to reciprocating compressors, the new vane design was compact, had negligible vibration and was pulsation-free.

Netzsch Pumpen & Systeme GmbH is adding to its rotary lobe pump product portfolio with their new Tornado T1 XXLB-F size. The ...

Leybold has launched two compact rotary vane pumps – the SOGEVAC SV55 BI² and SV70 BI² – designed specifically for LC-MS and ...

Rotary-screw and lobed-rotor vacuum pumps are two other types of positive displacement pumps. Neither lubricated design is as widely used as rotary-vane and piston pumps, especially in smaller sizes.

The pump itself is a two-stage rotary vane. This is a type of oil-sealed vacuum pump that, as the name suggests, operates in two stages: High pressure and low pressure.
