SJ Stainless steel multistage deep-well submersible pump

Typical applications

Water supply and irrigation system

Lowering underground water level

Booster

Various industrial applications



Working conditions

Solid grain-or-fiber-free dilute clean non-corrosive liquids;

Maximum liquid temperature:*5

Maximunm working pressure:*0 bar

PH:6.5~8.5

Maxium diving depth:<=*0m



Scope of application

This series is applicable to circulation and pressurizing of the clean water and softened water;

This series is made from stainless steel **4 and has good corrosive resistance for conveying cold water containing small amount of oxides.It is also used for conveying slightly alkaline water and de-mineralized water.Pump made from stainless steel **6 and FPM is applicable to conveying highly corrosive liquid.



Curve conditions

The curve tolerance complies with ISO***6 shown in attachment A.

All curves are based on the measured values of 3***0V,*0HZ,***0r/min.

All measurements are carried out with gas-free water of temperature *0.The curve is applicable to kinematical viscosity 1mm2/s.In case density of the liquid conveyed by the pump is higher than that of water,it is necessary to use corresponding motor of higher output power.

The coarse part of the curve means the recommended performance scope.

The performance curce includes loss caused by check valve etc.



Performance curve

Q/H curve means flow and the curve of lifting height under the rated speed.

Power curve:P2 means power of each grade

Efficiency curve:Eta means the grade efficiency of the pump
