Description of Products

1) The assembly of a variable speed drive offers constant pressure of water according to the demand that there is, therefore, offers a quality of supply much more optimal than in traditional systems.

2) It also provides a much higher mechanical saving than other traditional systems, such as operating through a pressure switch or an electronic device such as the "Press Control". The soft startups and shutdowns ordered by the frequency drive make the pump not subject to premature wear.

3) Compared with traditional water supply methods, it can offer an energy saving that oscillates between 20% and 60%. This means significant savings in the cost of the invoice.

4) Installation and start-up quick and easy.

5) LCD screen display, the interface is easy to operate, no need of professionals to test or maintain.

Other Details

▲ Can you provide sample?

Samples and shipping costs shall be paid by customers. Sample cost can be applied for exemption in the next orders. Lead time of samples is 1 week.

▲ Do you offer packaging design?

Yes, we have professional designer department who can provide packaging design for free. While the product has MOQ requirements if you need a new design for packing.

▲ Can you customize a transparent panel for the variable speed drive inverter? What’s the minimum order quantity requirement?

We can produce a transparent inverter panel with ABS material, and the MOQ in one order should be more than 1,000pcs. You can contact our colleagues for more information.

▲ Can we ask for OEM services if we don’t have registered trademark?

We are legal factory, we must need the trademark registration license certificate and OEM production authorization if you need OEM services.

▲ What are the differences between the variable speed drive converters made by your factory and other converters?

We make variable speed drive converters only for water pump, they are of better performance, better stability and simpler operation. In fact, once you install and use or disassemble the variable speed drive converters, you will know the quality difference.

▲ What is the pressure regulation range of your variable speed drive converters? What volume of pressure tanks are normally equipped?

The variable speed drive converters and variable frequency water pumps we make have 0.3bar starting pressure of and 0.5-9bar pressure regulation range. Generally, a 5L pressure tank is equipped during the using process. Of course, you can also configure 8L or 12L pressure tanks.
