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.

Yes, if your quantity of dc solar pump is more than 20pcs, we will give extra 2-3% discount, if more than 100pcs, we will give extra 5% discount

Kindly to know our DC brushless solar bore pumps are with permanent magnet synchronous motor, so not all the controller can be used for our pumps. The pumps should be matched with our own controller and our controller also can not be used for other pumps

We have two types of solar pump, the one with plastic impeller which is with 201 pump body. The other type is with 304 stainless steel impeller and 304 stainless steel pump body.

A PV system is made up of different components. These include PV modules (groups of PV cells), which are commonly called PV panels; one or more batteries; a charge regulator or controller for a stand-alone system; an inverter for a utility-grid-connected system and when alternating current (ac) rather than direct current (dc) is required; wiring; and mounting hardware or a framework.

You will more than likely have a small leak somewhere, if the pump is connected to the internals of the home. The first place to check is the toilet, in most case the washer in the toilet system is leaking letting water in, place a piece of toilet paper in the back of the toilet pan, if the paper gets wet, you have a leak.

If you want to have good tap pressure, than a pump is required, if you only want to hand water the garden and there is enough head pressure in the tank then you may not need a pump, but in most cases a pump is the better option.

A pool pump must be installed by a licensed or certified electrician or a qualified pool serviceman in accordance with the National Electrical Code and all applicable local codes and ordinances. Improper installation will create an electrical hazard which could result in death or serious injury to pool users, installers, or others due to electrical shock, and may also cause damage to property.

Yes….there is the risk of electrical shock or electrocution.

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.

In fact, our company have two nuclear products, electri cal deep well pump and solar bore pump, the regular delivery time is about 30days after deposit, the latter needs about 10-15days to delivery

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.
