Hydraulic diaphragm type metering pump product features and components

October 19, 2023

The hydraulic diaphragm metering pump is also called a plunger diaphragm metering pump. The plunger diaphragm metering pump drives the hollow plunger 10 to reciprocate by the driving gear 2, and drives the metering diaphragm through the hydraulic oil in the hollow plunger 10. There is a specially designed adjustment air on the hollow plunger to make the hydraulic oil inside and outside the plunger the same. The outer sleeve of the plunger is provided with an adjustable slip ring for closing the adjustment air. When the adjustment hole is closed, the plunger pushes the hydraulic oil inside to drive the metering diaphragm 6. In each stroke, the amount of hydraulic oil pushed by the plunger to drive the metering diaphragm is exactly equal to the amount of medium being metered.

The hydraulic diaphragm type metering pump is composed of a pump head, a diaphragm, a check valve, a valve ball and the like.

Hydraulic diaphragm metering pump features:

1. The measurement accuracy is better than the mechanical diaphragm pump, and the sealing performance is better than the plunger pump;

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

3. With the stroke adjuster can realize remote automatic control;

4. The diaphragm is pressed into a multi-layer composite structure:

The first layer of super-tough Teflon acid-resistant film; the second layer of EPDM elastic rubber; the third layer of 3.0mm SUS304 supporting iron core; the fourth layer is made of reinforced nylon fiber; the fifth layer is completely covered with EPDM elastic rubber, which can effectively raise the diaphragm Applicable life.

Metering pump metering pump measuring range: 0-125L / H, pressure bearing range: 0-25MPa, driving mode: motor drive, control mode: manual, automatic control, configuration: pump head insulation, cooling, motor can be equipped with explosion-proof.
