Description:

This series products work theory features is mechanical diaphragm metering pumps work by turbine and worm through motor driven for 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 exhaust 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 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.

Metering pump structure:

The pump by the reduction parts, eccentric adjustment, over-current components.

Slow parts: worm gear and worm deceleration institutions.

Eccentric adjusting parts: consists of adjusting the CAM, the piston rod and reset spring

Over-current parts: by the diaphragm, diaphragm clamping component, the inlet and outlet of the pump head and check valve

Application:

Better dosing accuracy than Mechanical Diaphragm Dosing Pump,
Better sealing than Plunger Dosing Pump.

Suitable for strong corrosives, volatiles, easy-crystalizing, inflammable, explosive, highly toxic, high density, high viscosity, and valuable liquids. Also capable for turbid liquid.

Widely applied in Petrifaction, chemical industry, refinery processes, power plant boiler water treatment and so on.
