This is basically a Plunger Pump and is similar to Single acting Plunger Pump. The main difference is the liquid is sucked and discharged on both the suction and discharge stroke has two way inlet and outlet is provided for above operation. . It is a positive displacement electric motor driven pump. Well equipped crank connecting rod mechanism convert the rotary motion of motor to reciprocating movement of Plunger.

We can vary the capacity from zero to maximum by stroke length adjustment mechanism. The liquid part can be offered in SS 304, SS 316, Alloy 20, Hestalloy B or C, Teflon or any other material as required by the user.

Duplex Plunger Pumps are recommended for high pressure high head. They are offered in various models with flow rate up to 25,000 litres per hours and maximum pressure up to 450 kg/cm2. The higher grade corrosion and fatigue resistance material is used as ‘PLUNGER’ to suit application. Plunger Pumps are offered with metering device or as fixed stroke version. The advantage of these pumps to achieve higher capacities or different liquids can be pumped. All different heads can be set to desired flow rate and pressure or you have choice of selection of heads to run or shut off services not required without any trouble or interruption to each other heads.
