Welcome to Jonson Quality Assurance!
The products you buy can be traced back to the production line for quality assurance inquiry.

Product Assembly & Inspection

We are dedicated to the technology development of precision gear pump and work on the precision producing, each JONSN precision gear pump comes into being, all coagulate the artisan spirit, their strict requests & outstanding performance to the products, accomplish the development of enterprise.

Performance Testing

A. No-pulse accurate delivery pump, provide continuous accurate delivery through the gears, delivery accuracy can reach +/-0.5% with the servo or stepper motor.

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

C. No-leakage, magnetic drive and static O-ring can ensure the inside pump medium isolated from the outside.

D. Excellent workmanship & MD, the modular designs optimize the gear shaft, pump body flow channel, and 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.

E. 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.

Inspect Qualified Products

  • Gap Calculating

    The pump body & gear deformation data from -60°C~180°C, the gap can be adjusted according to the operating conditions.

  • Processing Accuracy

    We have progressive processing center, precision gear hobbing, gear postprocessing workmanship and gear precision detector equipments support etc.

  • Stable Work Condition

    When the medium viscosity, temperature & outlet pressure are stable, the output flow is constant, or the flow will be fluctuant.

  • Motor Speed Control

    The accuracy of flowrate depends on motor speed, so selecting high-efficiency & stable motor is very important.
