Features:

Pulsation-free precise converying 

Positive displacement pump provide continuous precise conveying through the gears, converying accuracy can reach +/-0.5% with the servo or stepper motor.

Strong vacuum suction, high pressure and smooth delivery
HelpS to realize the low viscosity liquid delivery in middle & high pressure.

Zero leakage 
Magnetic drive and static O-ring ensure the inside pump medium isolated from the outside.

Excellent workmanship and MD
The designs optimize the gear shaft, pump body flow channel, and make it longer service life. We have lean manufacturing idea and adopt advanced processing technology & exquisite workmanship. It is an external gearing pump designed & manufactured for high-end application.

Model selection specialization 
We have rich operating experience in thousands of micro gear pump, accumulate lots of experiment data, specialize in selection evaluation, and formulate solution to reduce risks for you.

Advantages:   

Wide displacement range
0.18ml/r-17ml/r(Meet the request of most micro flow).

High pressure differential
1.0-25.5 bar(Normal), maximum 4Mpa.

Long service life
Gear& shaft adopt reinforced PEEK gears + high strength nano ceramic shafts combination, which are more wear resistant and greatly improved the service life of the pump. 
High gear consistency and interchangeability
Processed by Japanese precision CNC hobbling machine, gear consistency and interchangeability is high. 

Temperature range
-120ºC to 180ºC, we use high-performance magnetic material, improve inner magnet over molding process, completely solve the problem of high temperature thermal expansion and bulging.

High wear-resistance
By the use of high quality bearing grade PEEK modified material (confidential formula), relevant data is available. Wear resistance is ☆☆☆☆☆ by using of nano-ceramic shaft while using SS316L is ☆, and ceramic is ☆☆.

Long time operated under 100ºC ambient temperature.

Strong ability of industry application and accurate pump selection data analysis
By software instead of experience only.

Comprehensive testing ability
For all elements and the testing result is traceable in the systems.

High Gear accuracy testing capability 
By the German Winzer Gear Testing device.

Service life
>20000 hours while others normally 6000-8000 hours.
