How to size a positive displacement pump
WebJul 15, 2024 · The Double Disc Pump is a reciprocating positive displacement pump based on the induced flow principle. Induced flow happens when a vacuum is created due to the reciprocating nature of the pump and the fluid fills the vacuum void. Through a drive shaft, connecting rod and cam arrangement, the discs are rotated 180˚ out of phase, performing … WebJul 29, 2024 · Let’s say your pump is designed to generate 40 psi. With 3 psi of pressure on the fluid as it arrives at the pump, a pressure gauge at the inlet reads 3 psi. Since the pump is designed to create 40 psi of pressure, the discharge gauge reads 43 psi, and a differential pressure gauge reads 40 psi.

Reciprocating pumps include piston, plunger, and diaphragm types; rotary pumps include gear, lobe, screw, vane, and cam pumps.
WebSep 9, 2024 · Positive displacement pumps are affected by what’s known in the pump industry as “slip.”. Slip happens when a fluid that is being pumped “slips” away from the discharge side of the pump back to the suction side of the pump and is recirculated. Slip is influenced by system discharge pressure requirement and fluid viscosity.
