Hexa-plex pump

Plunger pump or also known as positive displacement pump is used to pump small amount of liquid at high pressure. In earlier days this particular pump was used for splash and lubricating system. The main components of plunger pump are the plunger and the inlet and outlet with two valves where they can open only in one direction. This pump is a reciprocating pump due to the alternate suction and discharge of liquid through the valve under different pressure influence. Positive Displacement Pumps has an expanding cavity on the suction side and a decreasing cavity on the discharge side.
