Scope of Application

The structure of the pump is designed to facilitate the replacement of the rotor, stator and liquid contact parts.

The axial size is small, 1/3–1/2 shorter than the pump of general structure, and the pump tends to miniaturization.
Low temperature effect, low working torque.
Self-priming ability is strong, up to 7–8 m; even at very low speed, the flow is stable. Usually used as a dosing pump.
Low energy consumption, suitable for making micro-pump — even a 40 W motor can work normally.
No pulsation, uniform flow, measuring accuracy is better than ±1%, suitable for the accurate measurement of small flow.
Simple maintenance and low cost. Easy to install and move.
