PTFE Diaphragm Hydraulic Metering Pumps Capacity range 10-400lph, 10-200bar JYSZ series hydraulic diaphragm pumps are an integrated pump that can offer precise dosing performance minimal maintenance. It is integrated safety valve against overload pressure. The PTFE diaphragm is durable and provides consistently accurate metering. Features of LIGAO Hydraulic Diaphragm Metering Pump: Ligao 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 adjusted via unique adjusting mechanism from 0-100%. The adjustment can be carried when pump is in operation or at stop. The steady sate accuracy is ±1% from 30%-100% of the maximum output. Automatic operation is achieved by variable speed drive. LIGAO hydraulic diaphragm metering pumps are capable of dosing corrosive, vaporing, flammable, explosive or toxic solutions. It can also transport suspended liquid or moderately viscous liquid. Double diaphragm with diaphragm rupture detecting system is available to prevent accident caused by mixture of hydraulic oil and the liquid after diaphragm ruptures.
