Product Description

 

Product Description

The NP series of micro magnetic gear pumps are exquisitely crafted for small flow rate conveyance. They shine in applications with flow rates spanning from 2 ml/min to 65,000 ml/min, covering transportation, addition, lubrication, sampling, spraying, dispensing, printing, pressurization, filtering, cleaning, circulation, coating, spraying, and metering.

Equipped with a small integrated DC motor with a built-in drive, these pumps are adept in confined spaces. With explosion-proof motors, they are safe for flammable and explosive environments. Paired with variable-frequency DC/AC motors, they are precise for metering tasks requiring speed regulation.

Dominating the low-viscosity micro gear pump domain, they handle 20 Bar pressure conditions with ease and boast a remarkable service life exceeding 20,000 hours. Compact, with rapid real-time dynamic responses, stable flow, high accuracy, and leak-free, they offer unrivaled solutions for fluid handling.
 

Working Principle

 

 

The theoretical displacement of a pump is directly proportional to its rotational speed.
In actual operation, due to the existence of rotating clearances inside the pump, internal leakage will occur, and the actual flow rate of the pump is less than the theoretical displacement.
The higher the viscosity of the liquid, the smaller the internal leakage in the pump and the closer the actual flow rate is to the theoretical flow rate.

Features of NP Series Pump Configuration

Special Gear Profile Design:
The special gear profile design with independent intellectual property rights endows the gears with outstanding wear resistance. The meshing feature of the gears, which is almost pure rolling, can minimize the wear during gear operation.
One-time Injection Molding Gears:
The working tooth surfaces of the gears adopt a high-precision one-time injection molding process without undergoing mechanical processing. This ensures the integrity and compactness of the structure on the gear working surfaces and improves the wear resistance and service life of the gears.
High-precision Ceramic Shafts:
The high-precision ceramic shafts possess super wear resistance and rigidity. They ensure the stability of the pump's operation under the conditions of abrasive liquids and high pressure, thus prolonging the service life of the product.
Capable of Long-time Dry Running and Self-priming:
In applications where the medium needs to be sucked into the pump by utilizing the inlet vacuum degree of the pump, the NP series products can provide reliable dry running performance, and the pump will not be damaged due to dry running during self-priming.
Pulsation-free Outlet Pressure:
The high-precision component processing and structural design guarantee the smooth delivery of liquids.
Special Casing Profile Design:
It can adapt to working conditions with a wide range of variations in outlet pressure. Whether it is low pressure, high pressure or short-term reverse operation, it can adapt well.The high-precision ceramic shafts possess super wear resistance and rigidity.
