NP600 | 6.0ml/rev | 0~18.9L/min | Dry running not recommended | |
NP900 | 9.0ml/rev | 0~28.0L/min | Dry running not recommended | |
NP1200 | 12.0ml/rev | 0~38.0L/min | Dry running not recommended | |
NP1700 | 17.0ml/rev | 0~55.0L/min | Dry running not recommended |
Choose the NP98 micro magnetic gear pump mainly according to the required flow rate. NP400 is suitable for lower-flow applications up to 12.6 L/min, while NP600 and NP900 cover medium-flow requirements up to 18.9 and 28 L/min. For higher-flow systems, NP1200 delivers up to 38 L/min and NP1700 up to 55 L/min. Final selection should also consider fluid viscosity, differential pressure, temperature, motor speed and operating conditions.

Filter Requirement: Install a 400-mesh (25μm) or finer filter at the pump inlet (or outlet for closed-loop systems). Ensure the filter's rated flow is at least 1.5 times the pump's rated flow to avoid pipeline resistance.
Dry Running Caution: Dry running is not recommended—prolonged dry operation at high speeds will cause permanent damage to PEEK gears and ceramic shafts. Always ensure the pump chamber is filled or wetted before use.
Pipeline Installation: Align pipelines with the pump's inlet/outlet to avoid eccentric torque. Use pipeline supports to prevent the pump body from bearing pipe weight, which may cause leakage or structural damage.
