China Hydraulic Diaphragm Metering Pump Manufacturers, Suppliers, Factory

Dongkai hydraulic diaphragm metering pump consists of three main devices;(1)driving device,(2)adjusting device,(3)liquid delivery device. The crankshaft which reduces motor rotation speed by worm and worm gear makes the piston reciprocate in the hydraulic oil chamber.This reciprocating movement of the piston makes the PTFE diaphragm and the liquid which is isolated by the diaphragm sucked and discharged. Each pump is with internal pressure relief valve protecting pump from over pressure conditions. The flow rate can be adjusted via unique adjusting mechanism form 0-100%;The adjustment can be carried when pump is in operation or at stop; The steady accuracy is ±1%from 30%-100% of the maximum output. Automatic operation is achieved by variable speed drive;
Double diaphragm with diaphragm rupture detecting system is available to prevent accident caused by mixture of hydraulic oil and the liquid after.
