The DSS series is a series of screw pump products. The characteristics of screw pumps are low power, high head, and small flow. It is suitable for some scenes with small flow, such as houshold water.DPC and DLR are both plastic impeller submersible pump series. This series is cost-effective, with a large flow rate, more suitable for agricultural irrigation, and is also the most popular product ser...

We can accept sample order.

Yes. The flow rate can be adjusted by setting the controller speed.

The battery is not necessary, you can just connect the solar panel. If you need it to work on rainy days or at night, you can connect the battery for power supply.

No, you just need to connect our controller.

Our water pumps are made of 201 stainless steel or 304 stainless steel. If your water pump is seriously corroded and rusted, is it because your water pump was hit during use? Maybe the pH of the water in your area is relatively high? Our solar well pumps can only be used in clean water.

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.

Q: What is the difference between DSS, DPC, DSC series? A: DSS series are solar screw pumps. The characteristic of screw pump is high head and small flow. Suitable for domestic water supply.DPC series are solar-powered plastic impeller submersible pumps. It is cost-effective, has a long service life, is more durable than a screw pump, and has a larger flow rate. However, the head is relatively sma...

Q: When there is no water in the well, will DIFFUL solar pump automatically stop working? A: Yes. DIFFUL SOLAR PUMP has Intelligent water shortage protection function. The pump stops working automatically when there is no water in the well, and automatically start working 30 minutes later. The whole process does not require manual operation and is completed automatically. To read more about the so...

Q: Can I use the existing cable on my AC pump to power the solar pump? A: The solar pumps use a 4 core or 3 core 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. As long as the diameter requirements are met, the existing cab...

Q: Which is better--a DC or an AC pump? A: The DC pump can directly use the DC power generated by the solar panel to run the water pump. Reduce the power loss in the conversion process. Therefore, the DC pump is more efficient and requires fewer solar panels. The DC pump also does not require an inverter to convert the direct current generated by the solar panel into alternating current. Reduced c...

Q: Do I need batteries to operate an DIFFUL solar pump system? A: No. All of DIFFUL solar pump systems are designed to operate with direct solar. However, they can be operated via batteries if needed for on-demand use. To read more about the solar pump, contact us. E-mail/Skype:sales08..........comTel/WhatsApp:+86 15058288607

Q: How do I determine the amount of panels needed for my solar pump? A: The easiest way to determine this is to add 30% on top of the pump wattage for minimum requirements and recommended would be 50%. I.e. a 500w pump requires minimum 650w and recommended 750w to operate.When configuring and connecting solar panels, you also need to check the maximum working voltage and optimal working voltage ra...

Q: Will a solar pump stop pumping once the tank is full? A: DIFFUL solar pumping systems utilize a controller that among other things will accept the input from a float switch in your tank which tells the pump when to start and stop. We will give you a float switch in our accessories. Some of the other functions of pump controllers are low water cut-off, lightning protection and load matching thro...

Q: What are the probes used for and are they needed? A: 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. To read more about the expected lifetime, contact us. E-mail/Skype:sales08..........comTel/WhatsApp:+86 15058288607

It can be applied to countries with different voltages such as 110v and 220v. For more product information, please contact us. E-mail/Skype:sales08..........comTel/WhatsApp:+86 15058288607

Q: How long do the solar pump systems last? A: The solar panel has a power output warranty of 25 years and cause very little trouble. They have no moving parts to wear out. The motors in the brushless motor pumps have a 20,000 hour rating. Water quality and proper installation are key factors in how long the pumps will last. If the pumps are placed in sandy or dirty wells, premature wear is inevit...

Q: Can I use DIFFUL solar pump for salt water applications? A: No. The DIFFUL solar pump cannot be used for salt water. Can only be used in clean water. Salt water is corrosive to a certain extent, has a corrosive effect on the water pump, and will reduce the service life of the water pump. Moreover, the salt in the salt water will accumulate in the water pump, block the water pump, and make the w...

Q: How Much Water Do I Need For A Village Pump? A: This very much depends on the amount of people (and animals) dependent on the pump. Generally speaking, you can calculate with the following numbers in case of a central water pump: 20 – 50 liters / day per person30 – 150 liters / day per cow (depends very much on whether they are producing milk or not)5 – 10 liters / day per goat or sheep For mo...

Q: Should I use a tracker or fixed mount for my solar modules?A: The answer to this question depends on your application (domestic use or stock watering), the daily volume of water that you need and what time of year you plan to use the pumping system. For most livestock water pumping applications where the highest daily volume of water is usually needed during the summer, a tracker is highly reco...

Q: How can I receive a solar pump catalog?A: There is a solar pump product catalog on our website.

Q: What is a submersible Vs Surface solar water pump?A: The difference between these two types of pumps is in the names (among many other things). A submersible water pump is one that needs to be underwater at all times to function. These are best used in boreholes and wells. They tend to be more expensive to install and maintain. On the other hand, a surface solar water pump is one that stays abo...

Q: How far can I install the solar panels from the pump?A: 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. E-mail/Skype:sales08..........comTel/WhatsApp:+86 15058288607

Q: Can I use solar or wind power to keep my stock tank from freezing?A: That depends on how cold it gets at your site, if your tank is insulated/bermed and how you plan to keep your tank from freezing. Heating elements consume a lot of power to keep water from freezing which would require a large and expensive solar array to operate. There are bubbler system on the market that simply circulate the...

Q: What size cable and discharge pipe should I use?A: The proper size cable to use in between your controller and the pump depends on the What type of water pump do you plan to use and the distance you need to run the wire. The size of the pump's discharge pipe depends on what type of pump you plan to use, the distance from the pump to the tank and the GPM flow rate that the pump will produce. The...

Q: Can I use a solar pump to pressurize a tank for domestic use?A: Maybe. Keep in mind that 1 psi = 2.31 feet of head. I would not recommend using a diaphragm pump for this application because you run the risk of rupturing the diaphragm if your pressure switch malfunctions. Another reason not to use a solar direct pump to pressurize a tank is that your tank might get low in the early morning or la...

Q: How Do I Ensure That I Also Have Water When The Sun Does Not Shine?A: Normally, a storage tank is integrated in the design of a solar water pumping system. The storage tank acts as a “battery”. When the sun shines, the tank is filled up, when it is cloudy or dark, water can be used from the tank which is placed at a high point. It is also possible to include a backup battery in a solar water pu...
