Positive Displacement Pumps has an expanding cavity on the suction side and a decreasing cavity on the discharge side. Liquid flows into the pumps as the cavity on the suction side expands and the liquid flows out of the discharge as the cavity collapses. The volume is constant given each cycle of operation. The positive displacement pumps can be divided in two main classes,reciprocating,rotary and we have both at pumpbiz.

  • Reciprocating Pumps
  • Rotary Pumps
