Liquid Ring Vacuum Pump Power Calculation Formula

Capacities expressed in cfm or scfm standard cubic feet per minute can be very misleading because we have to take into consideration the volumetric efficiency of the pump at a specific vacuum.

Liquid ring vacuum pump power calculation formula.

Bkw 13 5 sf 1 088 where. Today s blog entry deals with quick but reliable estimate of the power consumption of vacuum pumps used in the chemical process industry. Concerning the power of liquid ring pump due to the absorption and the removal of the heat by the operating liquid the gas compression process in the liquid ring pump is generally regarded as isothermal one so the formula for the isothermal compression power of the ideal gas is commonly used to calculate the effective power of the liquid ring pump 12 13. Bkw 21 4 sf 0 924 rotary piston pump.

If the discharge pressure is increased then more energy or brake horsepower is required to operate at the increased compression range. Can you share everest screw vacuum pupm calculation link. Liquid ring pump 20 30 torr 2 5 torr. Liquid ring nash pump.

You might get a doubt that how the formula for pump capacity is derived but there is nothing but just a unit conversion by incorporating the required end vacuum i e ultimate pressure. Some equations are presented below for the benefit of the readers. By changing the discharge pressure the efficiency of the. Most liquid ring vacuum pumps are designed to operate from a vacuum suction to an atmospheric discharge pressure.
