Hydraulic Diaphragm Metering Pump 2DPMXAA

Adopt automatic oil supply and built-in safety 

protection technology, with mutual linkage of 

diaphragm limit valve-compensating valve-built-in

 relief valve. Accuracy of limit valve reaches

 surface hardness reaches 60-70HRC; roughness reaches 

0.4um; it can be used for 80 million times within -800℃-1600℃ temperature range.

reaches 99.92%, which reduces cold flow during 

operation and enhances compression strength.

Built-in automatic discharge, pressure relief

 and compensating valve owns outstanding performance 

and it is safe and non-leakage;

Inlet and outlet check valve uses high-level ball valve 

with strong corrosion resistance and linear sealing, in 

order to effectively ensure the metering accuracy and fluidity;
