Piston Pump Leakage

Single Acting Reciprocating Pumps 1. The Cylinder 2. The piston
In theory, a reciprocating pump will always deliver the same volume for each stroke regardless of discharge pressure. But, as discharge pressure is increased, there is more likelihood of internal leakage between the piston rings and the cylinder liner, ... Fetch Content
