Plunger pumps are positive displacement pumps that" displace" a given amount of fluid on each cycle stroke of operation .The reciprocating motion of a plunger, with a ball check valves on each side of the pump body, creates the pumping action. Pumps can be offered in simplex, duplex or multiple heads for handling different chemicals with common motor. Each head has independent connection and the capacity of head can also be independently adjustable. They can be single acting or double acting.
Plunger Pumps are reciprocating positive displacement pumps which are generally configured in four ways: direct-acting or indirect-acting; simplex or duplex; single-acting or double-acting; and power pumps.
A simplex plunger pump, sometimes referred to as a single piston plunger pump, is a pump having a single liquid ( pump ) cylinder.
