4SPJG Series Solar Pump

Adopt stainless steel casing, shaft core ,coupling ,water entry base and pump body ( or copper alloy water entry base ,pump body ) ,blower inlet casing ,impeller with new polymer materials of high-strength and wear -resistant. New"floating style" structure of impeller avoids axial pressure to motor . With combination of motor and controller, the max efficiency is over 85%, raises 20% than the traditional AC one .

1)  Stainless steel casing ,shaft core , coupling and pump body ; copper alloy connecting ,base , blower inlet casing ,impeller with new polymer materials of high-strength and wear-resistant.

2) Water immersion style stainless steel submersible motor: graphite bearing.

A.Compact structure ,high-lift,noiseless,pollution-free,complete electrical protecting controller device ,against under-voltage,over-voltage,over-flow,overload,waterless etc.automatic recovery ,controlling water height as demand

B. Easy installation,maintenance-free, safe and reliable. Water depth:1-180m  Max flow:2.5m3/h

These electric pumps series are workable maximum head ,as there are no restrictions of BDC ,With the addition of high head, high efficiency and wide high efficiency zone ,they are suitable for distance water irrigation, high efficiency of increasing oxygen on aquaculture ,pumping  water from deep well , gardening,fountain and etc.

1.Non-corrosive water , the volume ratio of sand content no more than particle size less than 0.2mm

2.Max medium temperature up to +400c. PH value remains 6.5-8.5

3.Work close to the rated head and must be immersed in water
