These pumps dis-charge liquid by changing the internal volume. Reciprocating pumps can gener-ally be classified as having a piston, plunger, or diaphragm, displacing a discrete volume of liquid between an inlet valve and a discharge valve. The rotary motion of the driver, such as an electric motor, is converted to the reciprocating motion by
