Axial piston hydraulic pump
Chinabase Machinery (Hangzhou)

•Metering accuracy is almost independent of back pressure

•Flow rate is linear to stroke length variation

•Diaphragm is always balanced between the pressure exerted by the hydraulic oil and 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

•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 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
