taiwan921.lib.ntu.edu.twPositive Displacement Machines Force fluid into or out of a chamber by changing the volume of the chamber. The pressure developed and the work done are a result of essentially static forces rather than dynamic effects. Typical positive displacement pumps: (a) tire pump, (b) human heart, (c) gear pump.
Positive Displacement Pump Basics - Fristam
fristam.caPositive displacement pumps use two opposing, rotating elements (rotors) to displace product from the suction side of the pump to the discharge side of the pump. As the rotors rotate, the chamber formed between the rotors, housing and cover collects the product on the inlet side
