Hydraulic Operated Diaphragm Type Dosing Pump

Easily handles corrosive, abrasive or viscous fluids
Steady state metering accuracy of +/-1 of pump output, at single setting of stroke from 10% to 100%. (turn down ration 10:1)
Repeatability better than +/-2.5% of set point
Flow metering accuracy is almost independent of back pressure of liquid
Discharge flow rate is linear to variation of stroke length
Automatic air bleeding from the hydraulic oil to ensure better metering accuracy
Arrangement of in-built pressure relief valve to protect the pump from pressure exceeding the rated pressure
Diaphragm is always balanced between the pressures exerted by the hydraulic oil and the liquid to be dosed.
