Description of Functioning: In this type of pump the Plunger is directly in contact of Liquid. It is Sealed by Special Packings to ensure minimum leakages.

Suction Stroke: When The Plunger moves backwards the it creates Vacuum & Discharge valve is closed & Suction valve opens allowing liquid to enter into the chamber.

Discharge Stroke: When the plunger moves forwards the it creates pressure & suction Valve is close & discharge Valve opens discharging fluid in the outlet pipe.

• 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.

• High flow rates of 0.5 liters/hr to 12000 liters/hr & high pressures of 400 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.
