Technical Specifications

Reasonable running, with soft starting and soft stopping, can eliminate water hammer effect. Therefore, the average motor shaft torque and wear will be reduced a lot. Not only reduces the maintenance cost, but it also greatly improves the life span of pump and the whole water supply system.
The constant pressure water supply system directly gets water from the source water, so it reduces the secondary pollution which is effective to prevent much infectious disease transmission.
It has high configuration flexibility, high degree of automation, rich functions and stable performance.
It is of small accounting area, less investment and high working efficiency
Energy efficient: pump VSD can help you save 20%-60% electricity and water which is eco-friendly.
Communication control: pump VFDs can help you achieve unattended control, saving manpower.

Application

The frequency drive water pump is widely used in constant pressure water supply system, firefighting apparatus, tall building water supply system, water treatment equipment, environment engineering and more areas.

Product Parameters

Other Information

What are your advantage?

Our industry and trade are integrated, and our factory mainly produces inverters, inverter pumps, permanent magnet inverter pumps, inverter fishery equipment and pump accessories. We have a complete set of standard management system from raw material procurement, production to product testing, and packaging and shipping, etc. Every product is tested before delivery.

Can you provide OEM or Customization of Colors?

If customers need OEM services, the minimum order quantity is 600 PCS per model in one order.

Can the inverter speed up the frequency of water pump by setting parameters?

No, it is automatic

What material and process is used for the inverter housing on your box-type variable frequency pump?

The box-type inverter shell is made of cold-rolled plates and painted.

What is your after-sales service?

Our quality warranty period is one year. Any quality issues will be resolved to satisfy customers.

How does the inverter react if the pump is dry-running ?

If there is dry running , the inverter will protect against water shortage in order not to damage the pump.
