has the high pressure ,widely used ,includes hydraulic diaphragm type

Pump head includes hydraulic diaphragm type and plunger type.

Hydraulic diaphragm metering pump boasts automatic venting/pressure release and automatic oil feeding valve, outstanding performance, safety and non-leakage.

Integrated worm wheel-worm variable transmission mechanism has low noise and high efficiency.

It makes use of excellent sleeve adjustable eccentric transmission mechanism, which is simple and reliable, and is capable of 10%~100% stepless adjustment of stroke.

Inlet and outlet check valve uses high-level ball valve with strong corrosion resistance and linear sealing, in order to effectively ensure the metering accuracy and fluidity.

High-performance plunger, German filling, diaphragm and sealing elements have long service life, and superior sealing performance.

Oil-immersed type lubrication ensures that variable transmission components can be used reliably for a long period.

Quantity adjustment range: 10%~100%

Metering accuracy: ± 1%.

The flow rate can be controlled manually, electrically or through variable frequency.
