Secure Features & Advantages

Explosive view:

Features:

1. 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.
2. Strong vacuum suction, high pressure and smooth delivery, help to realize the low viscosity liquid delivery in middle & high pressure.
3. Zero leakage - Magnetic drive and static O-ring ensure the inside pump medium isolated from the outside.
4. 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.
5. 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: 10-25.5 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.
