Pump Repair
Main Pump Types – Reciprocating, Diaphragm
In the next installment of our “equipment series”, we will discuss diaphragm pumps. A reciprocating pump uses positive displacment to move reciprocating (back and forth) parts through the use of a piston, diaphragm, and at times a plunger. While a piston uses an up and down motion, as seen in car engines, the diaphragm pump…
