The crankshaft which reduces motor rotation speed by worm and worm gear makes the piston reciprocate in the hydraulic oil chamber. This reciprocating movements of the pitston make 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 uniqe adjusting mechanism from 0-100%. The adjustiment can be carried when pump is in operation or at stop. The steady sate accurancy is ±1% from 30%-100% of the maximum output. Automatic operation is achived by variable speed drive. LIGAO hydraulic diaphragm pumps are suitable for crossive,vaporing, flammable, explosive or toxic solutions. It can also transport suspended liquid or moderately viscous liquid.  Double diaphragm with diaphragm rupture detecting system is availble to prevent accident caused by mixture of hydraulic oil and the liquid after diaphragm ruptures.
