Products Feature
- This variable frequency drive inverter is used only 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 installation is very easy with direct screw thread, it can be used different kinds of water pumps and thus reduce extra costs.
- The operation of this inverter is very easy, all functions can be finished by parameters setting, and you don’t need any professional staffs to debug.
- The range voltage is wild, it can work stably in areas with large voltage fluctuation.
- This VFD inverter is high-efficient, it can save water and electricity up to 20%~60% compared to old water supply system.
- LED display makes it convenient and fast to check and set actual pressure values.
- Soft starting and stopping, constant water pressure prolong the service life of the pipe Network and make the water usage comfortable and enjoyable.
FAQ
Q: Are you factory or trading company?
A: We are a manufacturer of inverter, inverter water pump, permanent magnet inverter water pump, inverter aerator pump, inverter feeder machine and water pump accessories, with ISO9001 quality system certification and many products with TUV, CE and ROHS certification. We provide high quality products at competitive factory price.
Q: What is lead time of your product?
A: We are factory, our lead time is about 20-45 working days.
Q: What's your quality control system?
A: 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?

Q: Can you provide samples for testing?
A: Customers should pay samples and shipping costs. Sample cost can be applied for exemption in the formal order. Lead time of samples is 7days.
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: Do you produce 110V inverters? What is the maximum power?
A: We produce frequency inverters for 110V water pumps with maximum power of 1.1KW.
Q: What material is the shell of the regular knapsack inverter?
A: The base is aluminum alloy and the panel is plastic.
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.
Q: What kind of transportation can you provide?
A: We can provide shipping by sea, air and express.
