NP series magnetic drive micro gear pumps have wear and corrosion resistance(316L stainless steel pump body & PEEK gear), strong self-priming and dry running abilities, small size(with integrated-drive motor), and long life expectancy. These features make them an ideal choice for your sampling processes.

With special materials and patented gear design, our pumps can:

- Run dry for up to 100 hours without damage*

- Build up a inlet vacuum of -0.85 bar

- Work under the ambient temperature from -40℃ to 100℃

Therefore, if your systems need to :

- Extract liquids from vacuum vessels

- Work outdoors at high temperatures

- Operate within limited space
- Remove the air without prior priming

- Run continuously and stably without checking or repairing Just contact us!

Our product lines have got CE certification.Our products are applied in widely fields,such as medical equipment, chemical industries, commercial machinery,laboratory analytical instruments, diesel SCR systems, lube systems, spray systems, coolingsystems, fuel cell systems, and lithium battery production lines,ect. The outstanding function of stability, long service life and high pressure performance have been deeply appreciated by our customers.

NP micro magnetic drive gear pumps use the magnetic field to drive the rotation of gears.The pumps are sealed only with O-rings, and eliminate the risk of dynamic seal failure.Gears (formed through one-step injection moulding) and bearings made of specially filled PEEK materials, high-precision industrial ceramic shafts, and patented gear tooth profile design, all these components ensure the outstanding life expectancy and wear-resistance of our products.

NP pump is an ideal choice for meeting the demands of low flow rate, high pressure, few fluctuation, corrosion resistance, corrosion resistance, and high temperature resistance.
