Micro Magnetic Drive Gear Fire Pump Self Priming 20 Bar
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.
Advantages of NP pump: High temperature resistance,High pressure resistance,Wear resistance,Erosion proof,Low operational noise,Self-priming capability,Long life expectancy,Dry-running for long time,Non-pulse and stable outlet
| Nominal displacement | 17mL/rev |
| Inlet-outlet differential pressure | 20 bar (transport pure water) |
| Liquid temperature | -120°C to 150°C |
| Life expectancy | longer than 20000 hours in liquids without impurities;100-hour continuous dry running |
| Inlet vacuum | -0.85 Bar (depends on rotational speed) |
| Electric motor | brushed DC/brushless DC/canned magnet brushless DC/ordinary AC/variable frequency AC |
| Operation noise at the speed of 2000 rpm | spur gear pump<55dB / helical gear pump<45dB |
| Rotational speed | 100 ~ 4000 rpm |
| Thread for connectors | standard type is NPT NPT 1/4’’,1/8’’,NPT 3/8’’ & NPT 3/4” and we offer other options |
| recommended inlet filter | 400 mesh, and in a closed-cycle system the filter should be installed at the pump outlet. Its passable area should be large enough to avoid affecting normal liquid flow |
