Features of Products
■ Reasonable operation, by soft starting and soft stopping, the VFD water pump can eliminate water hammer effect. It will greatly reduce the maintenance cost, and also greatly protects the life span of pump and the whole water supply system. |
■ The unit can keep water pressure stable, and you can adjust required pressure setting with several buttons. |
■ It is convenient and easy to check and set actual pressure values with the Led display. |
■ The use of pump VSD allows the system to work smoothly and stably by changing the pump speed to regulate the water supply, so that is the reason why constant pressure water supply system is of high energy efficiency and low cost. |
■ No water hammer occurred when the VFD water pump is in use. |
■ The interface operation is simple, there is no need of professionals for testing or maintenance. |
■ Water & electricity efficient: VFD water pump can help reduce 20%-40% water and electricity, it is eco-friendly. |
■ Easy installation and operation, it adapts to various kinds of pumps, greatly save the cost. |
