RUVAC WH/WHU

The RUVAC WH/WHU pumps series are technological leaders in the area of Roots vacuum pumps. Both motors and oil reservoirs are water cooled thereby perfectly balancing the internal temperature management of the pumps resulting in significantly lower oil temperatures and thus a longer oil service life. At ultimate pressure, emissions are reduced by approximately 50% and the motor coils can sustain higher loads while at the same time offering improved efficiency.
