Hydraulically Actuated Diaphragm Type
Dosing Pumps

Operating Range

Applications

• All kinds of Acids, Flammable liquids.
• Corrosive liquids, Costly liquids.
• Sod, Hypochlorite, Ceramic slurry, Hazardous acids, Aggressive liquids, Food products

Materials

• SS-316, SS-316 L, SS-304, SS-304L
• Duplex stainless steel
• Super duplex stainless steel
• Hastalloy-B & C, alloy-20 etc...
• PP, PVC, PTFE, GFT
• Diaphragm – PTFE only

Features

• These are glandless and zero leakage pumps.
• Flow rate is linear to stroke length variation.
• Metering accuracy almost independent of back pressure.
• Diaphragm is always balanced between the pressure exerted by the hydraulic oil & the liquid to be dosed. longer diaphragm life.
• Automatic air bleeding from the hydraulic oil ensures better metering accuracy.
• Arrangement of in-built pressure relief valve to protect the pump from pressure exceeding the rated pressure.
• with these pumps. these pumps with ria are provided with sandwich of two diaphragms. the rupture of any one of the diaphragms can be sensed by pressure sensing device.
• In case of metering pumps to be used in hazardous areas the liquid head can be kept at a remote place from drive side. the head & drive are coupled by hydraulic oil in flexible tube.
