A permanent magnet synchronous motor (PMSM) uses permanent magnets embedded in the steel rotor to create a constant magnetic field. The stator carries windings connected to an AC supply to produce a rotating magnetic field. At synchronous speed the rotor poles lock to the rotating magnetic field. Permanent magnet synchronous motors are similar to brushless DC motors.Because of the constant magneti...

Centrifugal water pumps use centrifugal force to pressurize and move water from the inlet to the outlet. A rotating set of vanes (called an 'impeller') is spun by the pump shaft. As water is forced through the impeller, rotational energy is transferred from the impeller to the water, which gains velocity and pressure through the centrifugal force applied and is flung from the impeller. The volute ...

Our company has two office, our headquarter and workshop are located in wenling Taizhou, and our sales department and branch company is located in Ningbo.

The warranty of our solar pump is 3 years, the lifetime of plastic impeller is 1 year and the lifetime of 304 stainless steel impeller is 3 years. Our alloy mechanical seal is with 3 years lifetime

The main product of our company is submersible solar bore pump, we have screw type and impeller solar well pump. Besides, our company pushed out new models,like swimming pool solar pump and surface solar pump(QB60 and JET)

In fact, our controller is with the function of auto-induction, when there is no water in the well, the pump will stop working automatically. But to make the duplicate protection, it is fine for you to match one in the well.

Our company is the manufacture specialized in AC and DC solar pumps, and featured with DC solar pumps. So it is much easier for us to make DC solar pumps, we have stock material. it is possible for us to offer sample of DC models. But AC solar pump is a bit different, it is much close to electrical pump. So the MOQ of 4inch AC type should be 50PCS and MOQ of 6inch AC type should be 20PCS

The system needs very minimal maintenance which includes cleaning of the panels on a regular basis. Cleaning maintains the efficiency of the panel without which the panel’s surface gets reduced exposure to irradiation from the dust and dirt on it. In comparison to diesel pumps, solar water pumps have a significantly longer life expectancy and continue to produce electricity for even longer than 25...

No. Lack of sunlight affects the working of solar water pumps. On such days, however, a hybrid power supply can be given to the pump. The pump can be connected to the state electricity grid or a diesel generator set after making proper adjustments in the controller. But such an arrangement should be made only after consulting the manufacturer of the solar water pump.

Relocation of the solar pump system is not advisable. However, the system can be relocated using a mobile mounting platform but the process is expensive and may also cause damage to the system.

The motor pump set for irrigation and domestic drinking water should have a capacity in the range of 0.1 HP to 5 HP. Although, municipal and rural community applications could choose a higher capacity solar pump. For a DC motor pump set, the discharge varies from 14 - 100 litres of water per watt peak of PV array while for AC motor pump, the discharge varies from 13 - 19 litre of water per watt pe...

Although DC pumps have an advantage over AC pumps in terms of higher efficiency and no requirement of an inverter for operation, the cost of DC pumps is higher. Also, the repair and maintenance of DC pumps are difficult in rural and remote areas due to lack of service centres in these areas.

The selection is based on the groundwater level and the water source. In the case of a borewell with a water table deeper than 10-15 metres, a submersible pump is used. If it is an open well, pond, etc, then using a surface pump is better. Also, the surface pump is installed when the water level is less than 10 metres. Based on the classification, the following types of motor pump sets are availab...

There are several different types of solar-powered pumps depending on how they have been classified. But primarily there are four types of solar water pumps--submersible pumps and surface pumps, direct current (DC) pumps and alternate current (AC) pumps.Submersible pumps: As the name suggests, a submersible pump is located deep below the ground level and remains submerged under water. The suction ...

The advantages of solar water pumps over conventional electric pumps are given below:Solar water pumps do not require any fuel or electricity to operate. Once installed, solar water pumps do not incur the recurring costs of electricity or fuel.Does not get affected by power cuts, low voltage, single phase problems or the motor burning.Can be installed in remote areas where electricity is unavailab...

A solar water pump is used for extracting water from ponds, rivers, borewells or other sources of water which are then used to meet the water requirements for irrigation, community water supply, livestock and other purposes.

The probes are used to protect the motor from running dry. On the borehole pumps it's advised to make use of them, however, on swimming pool pumps they are not needed.

The solar pumps use a 3core cable and needs to be sized correctly based on the size of the solar pump required as well as the total cable distance. This is to ensure that the pumps performance does not get affected by volt drop over the cable distance. The cable size on the solar pumps are bigger than the standard AC pumps due to the lower voltages.

Yes, the 3rd Gen controllers come standard with a speed adjustment dial whereby you can reduce the speed of the motor if needed.

The controllers are not limited to wattage. You will need to make sure that the solar panels are connected correctly to avoid exceeding the voltage rating of the controller.

The easiest way to determine this is to add 1.3 times on top of the pump wattage for minimum requirements and recommended would be 1.4 times. I.e. a 500w pump requires minimum 650w and recommended 700w to operate.

It is possible to run the pump directly off of a battery bank. You will need to make sure that the voltage of the battery bank falls within the input range of the controller.

The Solar pumps we use work on low voltage so extending the cable too far will affect the performance and thicker cables need to be used to counter the volt drop.We would not recommend extending the cable more than 100-120m depending on the size and voltage of the pump. It's best to increase the cable between the controller and pump and keep the cables between the controller and panels as short as...

The motors that we use are AC low voltage motors which means that they do not work with brushes at all. The only wearable parts on the motors are the bearings and mechanical seals like normal AC motors.

The controller does not have the input for mains or generator power but the pump can be powered by means of a DC power supply that can supply the controller the correct voltage and amperage for the pump to operate efficiently.

You can increase the power to the controller, however, you will need to make sure that the voltage input to the controller remains within the limits. The additional power will not increase the peak flow rate; however, the additional power will allow the pump to run more efficiently during the early mornings, late afternoons as well as during cloudy days.

You do not need to add batteries in order for this pump to work, however, the 3rd gen controllers have the battery function built in so adding batteries at a later stage is also possible.

Head is the maximum vertical height above the pump that the water needs to be pushed and this also includes the losses over the distance that needs to be pumped.

Solar pump is as the new technology product powered by solar energy

A solar water pump is used for extracting water from ponds, rivers, borewells or other sources of water which are then used to meet the water requirements for irrigation, community water supply, livestock and other purposes.

Solar pumps operate on solar energy available free with nature, and thus save expenditure on diesel or electricity.The cost of operation and maintenance of solar pumps is negligibleUseful for water pumping in remote areas without grid power.
