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.


  • Positive return WELCRANK mechanism
  • Linear relationship between control setting and stroke length
  • Capacity is adjustable precisely from zero to maximum while the pump is stationary or in operation.
  • Metering accuracy of + 1 % of pump output-at-any single setting from 10% to 100% of capacity.
  • Multiplexing Facility allows to coupled of several pump, driven by one common motor, flow of each pump can be independently set or stopped as required.
  • Drive side mechanism (power end) totally enclosed and running in oil bath with automatic lubrication & provided with transparent automatic constant level oiler.
  • Jacketed pump for heating / cooling arrangement.

All wetted parts, depending on the nature of the metered fluid, can be manufactured from cast steel, SS 304, SS 316, ALLOY-20, Hastelloy ‘B’ or ‘C’ Polypropylene, UHMWP 25% glass filled Teflon, Teflon, etc.
