1. Ifthe pump has any minor faults, it must not be allowed to work.2. ifthe pump in the process of using a strong vibration, we must tentatively work,check what caused the cause. Otherwise it will cause damage to the pump.3. Theinterface between the pump and the pipe must be sealed, because if there is anydebris, it will damage the inside of the pump.4. afterthe use of the pump must pay attention ...

The selection of the waterpump should be based on four aspects of the liquidflow, head, piping layout and operating conditions.1、1. The pump flowrate is one of the important function data of the water pump selection. When selecting a pump, use the maximum flow as a basis toplan normal flow. Normally 1.1 times the normal flow is the maximum flow.2. The waterpump Max head is another important functi...

The discharge rate from solar powered pump depends on the radiation and not on the temperatures. In fact, the power generated from solar panels decreases (slightly) with increase in ambient temperature and thus, water outflow from a solar powered pump at higher ambient temperature will be slightly lesser than at a lower ambient temperature for the same level of incoming solar radiation on the sola...

A solar powered pump works like any other available and commonly used water pumps. The main difference is that solar powered pumps run on solar energy and do not require any fuel (diesel, kerosene, gas, etc.) or external source of electricity (from an electricity company) to deliver water.

Solar panels that are installed for a solar powered pump normally have tamper-proof hardware to make it difficult for miscreants to take the panels away. Panels are mounted on the structure using anti-theft nuts and bolts, which make it difficult to open and to dismantle the modules from the structure. The only way a panel can be stolen is if those bolts are cut – an undertaking requiring a lot of...

Though it is possible to remove and re-locate solar panels, it is not advisable to change their location

A 2 HP solar powered pump can usually carry water over a horizontal distance of 700 metres, though pressure is somewhat reduced at the end of the plastic pipe. However, the flow of the water from the pump would also be influenced by the local regional topography. Hence, the above measures are tentative figures.DIFFUL is an innovative and technologically advanced solar pump manufacturer, specializi...

The following table can be used as an indicative guide for the selection of adequate ratings for solar powered pumps for different farm sizes:Solar Powered pump rate powerApproximate time required for irrigation per acre0.5HP20hours1HP14hours2HP7hoursHowever, other factors like the type of crop to be cultivated, soil type, climatic conditions, water table, etc., also play an important role in dete...

Any given pump has a rated capacity and maximum flow rate. As a result, increasing/integrating more solar panels as compared to the rated requirement for a particular capacity HP pump does not result in a higher water output.However, since solar powered pumps work on the output from the solar array, increasing the number of panels in some case may increase the number of hours that the pump can ope...

A solar powered pump is rather quick to install and to commission. If an existing diesel pump on an existing bore-well is to be replaced with a solar powered pump, field work of 3-4 days will be required. Generally, the installation of a solar powered pump will take about 3-4 days depending on the size of the installation. Examples from the field shows successful installation of a 7.5 HP solar pow...

It makes sense for a farmer to generally choose a solar powered pump under the followingcircumstances: 1.Installation of new pump in a farm2.Replacement of existing diesel/pumpin a farm

Sure, our factory has ISO9001 and our dc solar pumps have CE certificate, besides, if you need UL, PVOC or something else, our products all can pass and we can make for you

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.

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.
