Features of Products
■ The frequency conversion water pump combines SPWM and pressure sensing technology, detects actual pressure change in the pipeline, the motor rotational speed will change according to current consuming water capacity for saving power and electricity costs.
■ Dry-running detection. It will shut down automatically while no water flows in, to prevent motor from burn out due to water outage.
■ Soft start and soft stop reduces the violent torque, therefore extending the life of motors.
■ Constant pressure water supply system improves the life quality, make water usage comfortable and enjoyable.
■ Complete protection functions and reliability, including under voltage, over voltage, over current over heat and so on.
■ Setting pressure through buttons and Led display directly.
Application
The frequency conversion water pump is suitable for distributing water under constant pressure & flow in residential housing, supermarkets, commercial buildings, resorts, complexes & industrial applications where the incoming municipal water supply pressure is inadequate.

FAQ
▲ Is there a minimum order quantity requirement for your variable frequency pumps?
Since we are manufacturer ourselves, normally we don’t have MOQ requirements, but there are shipping costs, customs clearance costs and so on. So it will be more economical if you order larger quantity.
▲ Which frequency inverter is generally used for single-phase pumps? How to choose?
For single-phase water pumps, you can consider using our M 220V single-phase in and out series horizontal inverter. The power of the inverter should be the same as the motor or bigger.
▲ Can your 220V single-phase input and 220V three-phase output be used for 380V water pump?
Yes, but you have to change the connection method to delta connection.
▲ Why do we need to install a pressure tank for the VFD water pump?
In order to keep the stopping pressure stable and stop normally, the frequency drive water pump must install 2L-24KL pressure tank, normally we install it on the five-way.
▲ Does the variable frequency water pump have continuous working time? For example, 73 hours of continuous work?
For only one VFD water pump, NO; for multi-pump connection more than two pumps, they have.
