Function of Plunger Pump: A plunger pump is a type of positive displacement pump where the high-pressure seal is stationary and smooth cylindrical plunger slides through the seal. A plunger pump allows use at higher pressures. In this type of pump the Plunger is directly in contact of Liquid. It is sealed by Special packing’s to ensure minimum leakages.
Function of Suction stroke: When the Plunger moves backwards then it creates Vacuum & Discharge valve is closed & Suction valve opens allowing liquid to enter into the chamber.
Discharge Stroke: When the plunger moves forwards then it creates pressure & suction Valve is close & discharge Valve opens discharging fluid in the outlet pipe.
Applications:
Dosing against High pressure.
Where High Accuracy is required.
Simple to Operate & Maintain.
Suitable for use for Handling Chemicals Compatible with SS 316 OR any other Metals Only.
Key Design Features
High flow rates of 0.5 litres/hr. to 12000 litres/hr. & high pressures of 352 Kg/sq. cm. can be achieved.
Steady State metering accuracy of + /- 1 % of pump output, at single setting of stroke from 10% - 100% (Turn down ratio 10:1).
Reproducibility (Repeatability) better than +/- 2.5 % of set point.
Easily handles viscous fluids. They are compatible with most of fluids.
Positive return of plunger and variable stroke mechanism allows linear relationship between control stroke settings and stroke length.
They have Low NPSHR requirement.
Simplex and Multiplex arrangements of pumps available for universal use.
Heating or cooling jackets for liquid head is also available.
