Products Feature

This variable frequency drive 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 range voltage is wild, it can work stably in areas with large voltage fluctuation.
The installation is very easy with direct screw thread, it can be used different kinds of water pumps and thus reduce extra costs.
This VFD inverter is high-efficient, it can save water and electricity up to 20%~60% compared to traditional water supply system.
LED display makes it convenient and fast to check and set actual pressure values.
The operation of this device is very easy, all functions can be finished by parameters setting, no need any professional staffs to debug.
Soft starting and stopping, constant water pressure prolong the service life of the pipe Network and make the water usage comfortable and enjoyable.

Q: What is the warranty of your products? And after-sales service?
A: We provide 12 months guarantee after shipment, and our after-sales department will respond to your questions in 24hrs and we provide lifetime maintenance.

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: Can you provide samples for testing?
A: Customers should pay samples and shipping costs. Sample cost can be reduced 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 CTN; for 4KW and 7.5KW inverters, there are 4PCS in a CTN

Q: Can we use only one pressure sensor when the variable frequency pumps are connected in multiple pumps?

A: Technically speaking, when the variable frequency water pumps are connected in multiple pumps, you can use only one pressure sensor. However, considering that the pressure sensor is a vulnerable part, it is recommended that each frequency inverter is equipped with a pressure sensor.

Q: What are the wiring methods of the inverter?

A: There are two wiring methods: 220V water pump with delta connection; 380V water pump with Y connection. If you have any questions during the usage, you can consult us at any time.

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: Can you provide packaging design?

A: Yes, we have professional designers who can provide packaging design for free. Of course, the product has a minimum order quantity.

Q: What are your payment terms?

A: 30% deposit before production, and 70% balance before shipment.

Q: What are your main markets?

A: Europe, North America, South America, Australia, Middle East, Russia, Central Asia，Southeast Asia, etc.
