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.

The different types of pumps are :(a) D.C. surface centrifugal pumpset(b) D.C. submersible pumpset(c) D.C. swimming pool pumpset(d) A.C. submersible pumpset

We have patent for our DC permanent magnet synchronous motor. Besides, we will use the best material for the spare parts. 1. 304 stainless steel impeller and pump body 2. 321 stainless steel shaft 3. NSK bearing 4. Alloy mechanical seal 5.MPPT controller

First, we are so sorry that we have no plan to attend this April caton fair. Our factory is located in daxi town wenling city, a bit far from Guanzhou. If you take raliway will cost about 8 hours, by flight to taizhou, and we can come to pick you up. It will be about 2 hours

Except for the brushless solar pump, our electrical submersible well pumps and surface domestic water pumps can be customized

all the times, we can do QB series solar pump, but our type is with stainless steel pump body. The price is a bit high, in April, our company turn to making cast iron pump body type, the price will be much more competitive

With more than 1 years' research and development, our company have our own screw solar pump. From April 2017, our factory will comprehensively make these model, meanwhile i will update the product list on my website as soon as possible

Firstly, your first order should be at least 100PCS, then your should create at least 30,0000USD per year from us

Sure, to carter to the peak sales season, if your order of DC solar pump reaches 20PCS we will give discount, and if you would pay to our alibaba account in March, we will give extra 5% discount

Kindly to know our DC solar pump with permanent magnet synchronous motor is our patented product, that's why our price is more competitive than other factories. Besides, our 2 inch small DC solar pump with mini design is unique of our company. Most other factories exported with their own brand, but we can do OEM for our clients.

our solar pump can be divided into two kinds, one is with induction brush motor, the other is with permanent magnet synchronous brushless motor. The DC former type is with cheap price and can be operated by solar panel directly.
