*working principle


Absorb the pulse in an instant, so as to obtain a smooth flow and pressure, which can smooth 90-95% of the pulse.

Airbag type, diaphragm type, gas-liquid contact type and bellows type.
Airbag shell material: stainless steel, carbon steel; airbag material: nitrile rubber, butyl rubber, fluorine rubber, EPDM, neoprene, etc .;
Diaphragm shell material: stainless steel, carbon steel, PVC and PTFE lined; diaphragm material: polytetrafluoroethylene + rubber (double layer);
Gas-liquid contact material: stainless steel and carbon steel;
Bellows material: stainless steel.


*Product Introduction


Water irrigation or diversion is not needed, the suction head lift reaches 7 m, the head lift reaches 50 m and the outlet pressure is 6 kgf/cm2;
Under smooth flow and good passing performance, the maximum allowable diameter of passable particles is 10 mm;
Slurry or sundry pumping brings little wearing to a pump;
Head lift and flow can be steplessly adjusted via air valve opening;
Pumping media are completely separated from working media and won€™t have any external leakage;
A pump can work while immersed in media;
Liquids relatively viscous can be transported as well (with a viscosity below 10,000 cP);
Oil lubrication is not required for a pump with no influence on it even when idling.
