A one stage liquid ring vacuum pump in OEM construction.
A close coupled pump where the motor is mounted directly on the pump casing
to take up as little space as possible when the pump is mounted in the system.
Evacuation and pumping of dry gases and saturated steam.
Typical industries are chemistry, pharmaceutical, food, plastic and rubber industry.
Vacuum is used for distillation, drying, degassing, filling and boiling.
The pump works according to the liquid ring principle. Liquid ring pumps are in some regards related with displacement pumps since the pump wheel is eccentrically located in the round pump body. When the wheel is rotating a fluid ring is created along the pump body's inner wall. In the cells (the space between the pump body's wings) inside the fluid ring rising part volumes (intake) and then decreasing volumes (outlet) will be created under one rotation.
