Overview

Roots Vacuum Pumps

Roots vacuum pumps RUVAC, which are also called Roots blowers, are rotary plunger type pumps where two symmetrically shaped impellors rotate in opposite directions inside the pump housing. Roots pumps are used where great volumes have to be pumped. In combination with backing pumps, which compress against the atmosphere, these pumps are capable of improving the attainable ultimate pressure of a pump system by a factor of 10. With two Roots vacuum pump stages and a corresponding backing pump it is possible to attain pressures in the range down to 10-5 mbar (0.75•10-5 Torr). Regarding the motor concept RUVAC pumps are offered in different models.

RUVAC WA / WAU

The series RUVAC WA Roots vacuum pumps are provided with directly flange-mounted air-cooled standard three phase motors. The oiled radial sealing rings of the RUVAC WA for sealing the shaft against the atmosphere are made of FPM (FKM) (fluor polymer). Roots vacuum pumps of the series RUVAC WAU are provided with an additional integrated pressure equalization line and a differential pressure valve. Pumps from these series are supplied with a vertical pumping action as standard.
