Percision Micro Gear Pump & 0-1.50L/Min

The NP010 micro magnetic gear pump delivers 0.1ml/rev nominal flow accuracy, eliminating fluctuations in liquid transfer. This precision is critical for applications like pharmaceutical dosing or analytical instrument feeding, minimizing material waste and ensuring consistent process outcomes.

With a 20mm compact body, the NP-20 Series pump requires minimal installation space. It integrates easily into small-scale equipment (e.g., portable diagnostic devices) without compromising performance, reducing overall system size and design complexity.

The pump operates across -20–60℃ and handles media with 0.3–100 mPas viscosity, adapting to water, low-viscosity chemicals, and biological fluids. This versatility makes it suitable for both indoor labs and industrial environments with temperature variations.

Boasting a 20,000h service life, the pump reduces maintenance frequency and replacement costs. Its robust internal gears resist wear, even during continuous operation, ensuring long-term stability for critical processes.

At <60dB operating noise, the pump is ideal for noise-sensitive spaces like medical clinics or research labs. It maintains a quiet workspace without sacrificing flow performance, enhancing user comfort.

With IP55/IP57/IP68 protection rating, the pump shields against dust, water splashes, and temporary submersion (IP68). This durability extends its use to harsh settings, such as chemical plants or wet-processing equipment.

The NP-20 Series is a staple in life sciences, supporting:

Analytical Instruments: Precise liquid supply for chromatographs and particle analyzers.

Diagnostics: Controlled dosing for sample preparation and flow cytometry.

Biotechnology: Stable transfer of sensitive biological fluids (e.g., cell cultures).

It excels in mechanical processes requiring accuracy:

Adhesive Dosing: Consistent application of adhesives in electronics assembly.

Minimum Quantity Lubrication (MQL): Precise oil delivery to reduce machining friction.

Filling & Dosing: Reliable filling of small-volume containers (e.g., cosmetic samples).

For chemical handling, the pump suits:

Pharmaceutical Manufacturing: Safe transfer of pharmaceutical intermediates.

Fine Chemicals: Precise dosing of high-purity chemicals in lab-scale production.

Ensure the liquid viscosity stays within 0.3–100 mPas; avoid over-viscosity fluids to prevent gear jamming.

Install an ≤400 mesh inlet filter to remove impurities—this protects internal components and maintains flow accuracy.

The maximum allowable dry running speed is 1500rpm; prolonged dry running above this speed damages gears and shortens service life. Always prime the pump with liquid before use.

Use 3mm-spec inlet/outlet fittings to prevent leaks; mismatched sizes cause pressure loss.

Do not exceed 20 bar pressure differential—exceeding this risks pump body damage.

Clean or replace the inlet filter monthly (or as needed) to ensure consistent flow rate.

Inspect for unusual noise; grinding sounds indicate gear wear and require immediate servicing.
