Mechanical Booster Pumps for Vacuum Systems - Vac Aero

May 13, 2013 ... From the Roots pumping speed vs. pressure curve (Fig.2) you see that the highest pumping speeds are from about 10 down to about 0.01 Torr. On average a ... The Roots pump is generally called a booster when used for vacuum applications and a blower when used for low positive pressure applications.

Leybold Vacuum, Roots Pumps, RUVAC WA, WAU, 151, 251, 501 ...

The RUVAC WA and RUVAC WAU are Roots vacuum pumps which are driven directly by an electric motor. The WAU types have a pressure balance line between the discharge and intake flange. Standard RUVAC pumps are not suited for pumping of oxygen when the oxygen concentration exceeds that in the atmosphere.

EH Mechanical Booster Pumps - 5 Pascal

Air cooled motors – with water cooled options. • Quiet, minimum vibration. The EH mechanical booster pumps, based on the simple Roots principle, remain the favorite pumps for applications where high pumping speeds over 3000 m3h-1 / 1776 ft3min-1 are required in the pressure region of 0.01 to 50 mbar / 0.0075 to 37.5...

Roots vacuum pumps - Pfeiffer Vacuum

The principle of operation of single-stage Roots pumps corresponds to the operating principle of multi-stage pumps as described in Chapter 4.5. ... presence of a high pressure differential between inlet and outlet, a high level of energy dissipation is generated, which results in significant heat-up of the pump at low gas flows...

Edwards EH-1200 Blower Roots Vacuum Booster Pump

The EH mechanical booster pump, based on the simple Roots principle, remain the favorite pump for applications where high pumping speeds are required in the pressures in the region of 0.01 to 10 mbar. This pump must always be backed by another pump, which can deliver against a high-pressure differential to...

Osaka Vacuum, Ltd.:Roots Vacuum Pumps

This mechanical vacuum pump is also referred to as a mechanical booster when it is mounted to the front end of an oil-sealed rotary vacuum pump to increase the exhaust rate. A roots vacuum pump is normally used with a vacuum pump that can compress up to atmospheric pressure, such as a dry vacuum pump, oil-sealed...
