How to Size Liquid Ring Vacuum Pumps

blades and the liquid ring. Then, as the impeller rotates, the liq- uid ring compresses the gas and forces it out the outlet port. The information needed to accurately size a liquid ring vacuum pump includes: • inlet pressure, usually expressed in mm HgA. • inlet temperature. • mass flow rate, usually expressed in LB/hr and the...

How to Control Liquid Ring Vacuum Pumps

Typically for pressures of 100 mmHgA and less, some sort of anti-cavitation or suction pressure control is needed. The simplest type is a manual bleed valve such as a globe valve. If automatic opening and closing is required, then an inexpensive spring oper- ated diaphragm valve can be used. In this design, the suction.
