NP series magnetic drive micro gear pumps can transport different lubricants and coolants. Our products provide low flow rates and high working pressures, which is the feature especially needed by lubrication or cooling of small systems.

          Competitive advantages:

1. Convenient flow rate control by AC/DC variable frequency speed regulation

2. Few pressure fluctuation

3. Low operation noise

4. Self-priming ability

5. Compact

6. Long life expectancy
7. High working pressure

8. Low flow rate

     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.
