SOLAR POWERED PUMPS

SOLAR POWERED PUMPS

A solar powered pump is a pump running on the power of the sun. It makes efficient use of solar energy and converts it into electrical energy for pumping water to great heights. A solar powered pump can be very environmentally friendly and economical in its operation. This system operates on power generated using solar PV (photovoltaic) system. The photovoltaic array converts the solar energy into electricity, which is used for running the motor pump set. The pumping system draws water from the open well, bore well, pond etc. The water pumping system can be used to irrigate land, when the water is to be pumped from a depth of well or a pond.

SPECIFICATION OF DC SOLAR SUBMERSIBLE PUMP
 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:

Stainless steel casing, shaft core, coupling and pump body; copper alloy connecting, base; rubber stator of high-strength and wear- resistant Water immersion style stainless steel submersible motor; graphite bearings.

r
 Product Feature:

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

2) Easy installation, maintenance-free, safe and reliable.

 Application:

These electric pumps series are workable within 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.

q
 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.

SPECIFICATION OF AC SUBMERSIBLE PUMP
 Bearings With Sand Channels

All Bearings are water lubricated and have a square shape, enabling sand particles, if any, to leave the pump together with the pumped liquid.

 Inlet Steiner

The inlet strainer prevents particles over a certain size from entering the pump.

 Non-Return Valve

All pumps are equipped with a reliable non-return valve in the valve casing preventing black flow in connection with pump stoppage. Furthermore, the short closing time of the non-return valve means that the risk of destructive
water hammer is reduced to a minimum. The valve casing is designed for optimum hydraulic properties to minimize the pressure loss across the valve and thus contributes to the high efficiency of the pump.

 Priming Screw

All pumps are fitted with a priming screw, consequently, dry running is prevented because the priming screw will make sure that pump bearing are always lubricated. Due to semi-axial impellers of large pumps this priming is automatically provided. However, it applies to all pumps types that the water table is lowered to a level below the pump inlet neither pump more motor will be protected against dry running

 Stop Ring

The stop ring prevents damage to the pump during transport and in case of up-trust in connections with start-up. The stop ring which is designed as a trust bearing limits axial movements of the pump shaft. The stationary part of the stop ring is secured in the bowl . the rotating part is fitted above the collets.
