 catalyst, polymer (polymer injection in oilfield), oil sludge, oily sewage water and public works. 


Main Feature:


API 676 Standard

? 可實現液、氣、固體的多相混輸;

Faultless multi-phase delivery of liquid, gas and solid;

? 具有自吸能力: 吸程可達8m;

Self suction: Suction is up to 8 meters;

? 泵內流體流動時容積不發生變化,沒有湍流、攪動和脈動;

Volume of moving fluid is constant, no torrent, stir and pulse;

? 彈性定子形成的容積腔能有效地降低輸送含固體顆粒介質時的磨耗;

High wear resistance when deliver the high solid content through the elastic stator chamber.

? 可輸送高粘度、高含固率介質;輸送介質粘度可達100000CP,含固量可達60%;

It can deliver the fluid with high viscosity and high solid content: the max viscosity is up to 100000CP, the solid content is up to 60%;

? 流量和轉速成正比,借助調速器可實現流量的自動調節;

The flow is directly proportional to the speed of rotation, the flow can be automatically adjusted by speed regulator;

? 恒壓控制,防干運行保護;

Constant pressure control and dry running protection.

? 無閥系統--泵本身具有止回閥的作用;

Valveless system - pump has non-return valve function;

? 可以反轉;


? 可靈活應用于各個行業;

Versatile use in all industries;
