DJZ Series low pressure Diaphragm type Metering Pumps

DJZ Diaphragm Metering Pump

Summary

This series products work theory features is mechanical diaphragm metering pumps work by turbine and worm  through motor drivenfor low pressure fluid metering applications.
Diaphragm metering pumps  use the flexible diaphragm replaced piston, it driven by the drive mechanism for reciprocating movement to change the pump chamber volume, also with the action of pump inlet&Outlet valve to finish liquid exaust and drainage.

Diaphragm metering pump can according to the needs of variety of processes, the flow capacity can be regulate in the range of 0-100% , quantitative conveying no solid particles of corrosive or non-corrosive liquids. The pump head materials with a variety of choice as like PPH, PTFE, PVC, PVDF, RPP, SS304, 316,316 L.
 The diaphragm of  diaphragm metering pump can completely isolate the liquid flow and driven lubricant mechanism. Using high-technical design and uses the latest new type of PTFE and rubber composite diaphragm, can resist strong corrosion and greatly extends the diaphragm life.
