solar small power screw pump for irrigation
3ZST2.3/140-D72/1100
Profile:
Adopt stainless steel screw and rubber stator, permanent magnet brushless motor. With combination of motor and controller, the max efficiency is over 85%,raises 25% than the traditional AC one.
Material:

1. Stainless steel casing, shaft core, coupling, oil entry base and pump body to avoid rust or corrosion. New polymer materials of high-strength wear-resistant

2) Oil immersion style stainless steel submersible motor.
 
Product Feature:

1. Compact structure, high-lift, noiseless, pollution-free; complete electrical protecting controller device, against under-voltage, over-voltage, over-flow, overload, wateriess etc; automatic recovery; controlling water height as demand.
2. Easily installation, maintenance-free, safe and reliable.

Max Head: 1-110m, Max flow: 4.2m3/h.
 
Application:
1).These electric pump series are workable with maximum head, as there are no restrictions of BDC , With the addition of high speed, 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.
 
Working condition:

1. Non-corrosive water, the volume ratio of sand content no more than 1‰ Particle size less than 0.2mm.
2. Max medium temperature up to +40ºC;  PH value remains 6.5-8.5.
3. Work close to the rated head and must be immersed in water.
