Positive Metering Pump Pvt. Ltd products

Performance conforms to API 675. Precise metering devices. Plunger is hard chrome plated. Flow rate is linear to stroke length variations. External arrangement for flushing the gland packing to increase its life is also possible. Metering accuracy is almost independent of back pressure. 

Performance conforms to API 675. Glandless design and entirely Leak Proof operation. Integrated Pressure Relief Valve.Diaphragm is always balanced between the pressure exerted by the hydraulic oil and liquid to be dosed. Longer Diaphragm Life. Automatic air bleeding from the hydraulic oil ensures better metering accuracy. Manual stroke adjustment by eccentric.

Performance conforms to API 675. Glandless design and entirely Leak Proof operation. Integrated Pressure Relief Valve. Rupture indication arrangement (RIA)is an additional facility available with these pumps. These pumps with RIA are provided with sandwich of two diaphragms. The rupture of any one of the diaphragm can be sensed by pressure sensing device. Automatic air bleeding from the hydraulic oil ensures better metering accuracy. Manual stroke variation mechanism.

Glandless design and entirely Leak Proof operation. Manual stroke adjustment for flow variation. Splash type lubrication in gear box. Negative suction upto1.5Mtrs. maximum.
