The hydraulic diaphragm metering pump is also called the plunger diaphragm metering pump. The plunger diaphragm metering pump is driven by the driving gear 2 to drive the hollow plunger 10 to reciprocate and drive the metering diaphragm through the hydraulic oil in the hollow plunger 10. The hollow plunger has a special design to adjust the air, so that the hydraulic oil inside and outside the plunger is the same. The piston outside the plunger has a adjustable slip ring for closing the regulating air. When the regulating hole is closed, the plunger pushes the hydraulic oil inside to drive the metering diaphragm 6. In each stroke, the amount of hydraulic oil that is driven by the plunger to drive the metering diaphragm is exactly equal to the quantity of the measured medium.

The hydraulic diaphragm metering pump consists of the pump head, the diaphragm, the one-way valve, the valve ball and other components. Are there any characteristics that you know? Huaian hydraulic metering pump manufacturers Ke Yu mechanical belt everyone to understand:

Product features of hydraulic diaphragm metering pump:

1. the measurement accuracy is superior to the mechanical diaphragm pump, and the sealing performance is superior to the plunger pump.

2. no leakage, convenient maintenance, low noise, easy to use;

The 3. match stroke adjuster can realize remote automatic control.

The 4. diaphragm is suppressed by a multi-layer composite structure.

The first layer is super acid Teflon acid resistant film; the second layer EPDM elastic rubber; the third layer 3.0mmSUS304 supporting iron core; the fourth layer is reinforced nylon fiber supplement; the fifth level is EPDM elastic rubber complete package, it can effectively raise the diaphragm life.
