WebJun 7, 2024 · A positive displacement pump pushes a fluid by capturing a certain volume of it and pushing (displacing) it into a discharge pipe or system. An expanding cavity is used on the suction side of some positive displacement pumps, while on the discharge side, a decreasing cavity is used. WebA positive displacement pump works by using a screw, a blade, a vane, a lobe, a gear or diaphragm. It creates a chamber or cavity between the pumping elements and the cavity in which the fluid is temporarily stored is moved by the reciprocating or rotary motion along the pipe to its destination. fmcsa.gov clearinghouse
