Product features
- This inverter is used especially for water pump. It adopts the industry leading technique SPWM and pressure transmission technique, detects actual pipeline pressure change and controls the rotation speed of the pump.
- The operation of this device is very easy, all functions can be finished by parameters setting, without the need for professional debugging.
- This inverter is high-efficient, it can save water and electricity up to 20%~60% compared to traditional water supply system.
- Soft starting and stopping, constant water pressure, prolong the service life of the pipe network and make the water usage comfortable and enjoyable.
- Wide voltage range allows for stable operation even in areas with significant voltage fluctuations.
- The installation is very easy with direct screw thread, and different types of water pumps can be used, thus reducing the extra cost.
- LED display makes it convenient and fast to check and set actual pressure values.
Application
- Tap water booster system
- Household and residential water supply system
- Swimming pool water supply system
- Commercial water supply system
- Factory dormitory water supply system
- Industrial water circulation system
- Cooling water systems
- Cold water circulation system

FAQ
Q: What kind of products do you mainly produce in your factory?
A: Our factory mainly produces inverter, permanent magnet inverter pump, photovoltaic inverter deep well pump, inverter swimming pool pump, permanent magnet inverter shielded circulating pump and so on.
Q: What's your quality control system?
A: Our factory is certified by ISO9001 quality system.We have strict quality control system from raw material procurement, production to product testing, every product is done fatigue testing, calibration, temperature compensation before shipment. High quality is guaranteed.
Q: What is the warranty of your products? And after-sales service?
A: Our warranty time is 12 months after shipment, and our after-sales department will respond to your questions in 24hrs, remote instruction by PC network is always available and we provide lifetime maintenance.
Q: Is there MOQ with your product?
A: If OEM services needed, the minimum order quantity is 300 PCS for each model in one order. If customization of colors needed, the MOQ is 1000 PCS for each model in one order.
Q: Can you provide packing details for this product?
A: For inverters power below 2.2KW, there are 6PCS in a carton; for 4KW and 7.5KW inverters, there are 4PCS in a carton.
Q: Do you have built-in sensor and five-way inverters?
A: Yes, we produce inverters with built-in sensors and five-way? What's the power and quantity do you need?
Q: Which frequency inverter is generally used for single-phase pumps? How to choose?
A: For single-phase water pumps, you can consider using our VFA-10M series knapsack inverter. The power of the inverter is the same as the pump, or the inverter power is a little bigger.
Q: What are your delivery terms?
A: EXW, FOB Ningbo, CIF, etc.
Q: Is the working temperature same as the water temperature? What is the ambient temperature?
A: The working temperature is the temperature at which the water passes through the product, which is a little different from the water temperature. The ambient temperature is the temperature around the product, such as the temperature around the inverter.
Q: What is the maximum power of your 380V water pump inverter?
A: We produce 380V water pump inverter with maximum power 18.5KW.
Q: Can you customize inverters for swimming pool pumps?
A：We can customize the inverter for swimming pool pumps, but the inverter of the swimming pool pump displays the rotation speed. Our normal inverter displays the frequency. For specific cooperation details, please contact our colleagues in charge of overseas business.
Q: Can the frequency inverter you produce be used for deep well pumps? What are the requirements?
A: The frequency inverters we produce can be used for deep well pumps, and the length of the power cable cannot exceed 20 meters. The power of the frequency inverter should be larger than that of the deep well pump.
