Product Description:

1.  Description of solar pumps. 

CNBM Solar Water Pump is the pumping facility driven by solar energy, which consists of a solar pumping inverter and a pump. Solar water pumps kit is called  solar pumping system combining with solar arrays designed according to different head and daily water flow for application. System is widely utilized for agriculture irrigation,desert control,pasture animal husbandry,city landscaping,daily water supply, etc.


In recent years, with the development of photovoltaic products from city application to huge demands of agriculture,pasture,desert areas, CNBM Solar Pond Pump has become the leading products combining photovoltaic industry with traditional industry such as agriculture water conservancy,desert control,daily water supply,city landscaping, etc.


CNBM Solar Pump driven by infinite solar energy, works from sunrise, and stops at sunset, need no connection to grid power nor diesel oil and battery. System can irrigate directly or store water instead of electricity in a reservoir. Solartech Solar fountain Pumps works with sprinkling irrigation, drip irrigation and infiltrating irrigation facilities, can be more efficient for water saving and dramatically lower the cost of using fossil energy.


2. Technical Function

1>  High efficient DC brushless motor requires less solar array. Rich social benefits.

2>  Optional centrifugal pump for big flow and helical rotor pump for high lift.

3>  High efficient semiconductor device used in main circuit. High reliability. Up to 98% conversion efficiency  of controller.

4>  Independent intellectual property of dynamic VI maximum power point tracking (MPPT) algorithm. Fast  response  and good stability. 99% MPPT efficiency.

5>  Full automatic operation. Complete protection functions. Integrated with water level monitor to prevent

  overflow and dry running.

6>  Full aluminum alloy case. IP52 protection grade. Ambient temperature: -20~+60℃.

Product Specifications


3. Specification details. 

1> Flow: 0.4m³/h~22m³/h

2> Head: 10m~210m

3> Power: 0.1~3Kw


4. FAQ

1> May we ask if the bare pump or the whole pump system would be all right for you to arrange the delivery?

     The bare pump and the who systems would be all acceptable at your side. A controller will be equipped with the pump freely. Regarding the whole system, we can also make the best solar panels configuration according to your requirements. 

2> Does your controller have the MPPT Function?

     Yes, our controller have. This would be not a problem. 

3> Can your pump work automatically?

     Yes, it would be the basic advantage of solar water pumps.

Q:What does "ETA" mean in the selection of pumps?
Water pump selection table "ETA" is the meaning of efficiency. NPSH refers to the pump's cavitation margin.ETA is abbreviated as "efficient ratio", and Chinese means "water efficiency". The efficiency of the pump here is generally referred to as the efficiency of the pump design point because the actual efficiency of the pump varies with the pump operating conditions. The efficiency of the ETA can also be interpreted as the efficiency of the pump at the rated lift (or rated flow).
Q:1.5 kW three-phase pump with 600 meters line, should match what big line?
1.5 kilowatts water pump distance 100 meters, with 2.5 square meters of electricity enough
Q:What is the difference between self-priming and non self suction?
The self-priming condition of the centrifugal pump is that a small water tank is attached to the pump body. Don't use water every time you start. No suction, no water tank. And the use of volumetric Self-priming pumps, such as car cleaning, high-pressure pumps are in this category.
Q:Water pump maintenance what should be maintained?
1 by sound to determine whether the bearing is good. If the sound is abnormal, replace the bearing.2, check whether the impeller is worn, if worn, will affect the flow, lift, efficiency, need to be replaced.3, check whether the mechanical seal can continue to use, can not be used, need to be replaced4, check the oil tank is missing oil, such as lack of oil to the appropriate location.
Q:What will the water pump reversal situation?
Reversal will also water out, but the amount of water is small, belong to "pressure water" effect, as if a basin of water, we do not shoot outward and down, the water will be out of the basin.
Q:What are the quota items for the complete pump installation?
Pump installation / anchor bolt installation anchor bolt hole, fill oar vibration cushion installation
Q:What is the 10KV pump unit?
The 10KV pump unit, driven by a high voltage motor, is used for drawing water!
Q:The water burst how to repair?
If it is not too serious, with casting glue on the line, it is best to use serious brazing, don't use the electrode,
Q:90kw pump star delta start, in the end to use the circuit breaker, AC contactor (Star contactor, angle contactor), what kind of thermal relay?
The first thing to take the star delta start voltage step-down start, star rated by reducing root 3 times, power is also reduced, 90kw / V 3 = 52kw starting current is 5---7 times will reach the rated current of 52kw * 2 = 104A, starting current will reach 500----700A is normal, if you match breaker sister ordinary 800, D at the beginning of the special motor, they start filtering instantaneous current, 250 can be,The star delta starts with only three contactors, and there will be no 4The contactor can be more than 110
Q:Does the pump accessories have a shelf life?
No, they don't have a shelf life before and after the sale,Before selling, it is infinitely long, and there is no expiration date after the sale
