Miniature Metering Pump

Main features

The miniature gear pump is a fluid delivery unit composed of a micro pump head, driver and motor.

It is especially suitable for various liquid media (corrosive, toxic, easy flammable and explosive, hydraulic) transportation,sampling, circulation, shunting, spraying, flushing, pouring, cooling and lubrication. 

 

Working principles 

Fluid enters the pump via the inlet and fills the space between the gears.

As the gears rotate, fluid will be contained in the space formed by two gears and internal pump wall.

The fluid is brought to the outlet side by the turning gears where they mesh.

This meshing process forces the fluid out of the pump through the outlet.

The established pressure is dependent on the pump size, gear clearance and pump rotating speed.

 

 

Pump structure

1. Small model and compact structure

2. 304 or 306 stainless steel pump body (required requirements), PEEK, PTFE, PPS gear, with self-lubrication, corrosion resistance, high temperature resistance, organic solvent resistance, high strength and friction resistance

3. Mechanical seal, no leakage.

4. The flow rate can be adjusted as needed.

5. The motor replacement is flexible, and various motors can be replaced according to actual needs.

6. Smooth operation and low noise

FAQ:

Q1: What does 0.1% repeat accuracy mean for production?

A: Flow fluctuation is only 0.1% under long continuous operation, stable A/B material ratio, reduce foaming defects and raw material waste greatly.

 

Q2: Is 70bar pressure enough for long pipeline delivery?

A: Max 70bar pressure supports long-distance pipeline, high-floor reactor feeding, no flow attenuation under high pressure.
