Product Features

The advantages of JONSN precision micro gear pumps are as follows:

■   No pulse accurate delivery – Positive displacement pump provide continuous accurate delivery through the gears, delivery accuracy can reach +/-0.5% with the servo or stepper motor.
■   Strong vacuum suction, high pressure and smooth delivery, can realize the low viscosity liquid delivery in middle & high pressure.
■   No leakage – Magnetic drive and static O-ring can ensure the inside pump medium isolated from the outside.
■   Excellent workmanship and MD – The 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.
■   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.
