VSNS no-negative pressure water supply system is energy-saving and  environmentally-friendly water supply system, using international advanced technology newly developed product. It is adopted advanced intelligent control technology, frequency conversion control technology, remote monitoring, stablized prevent negative pressure technology constitute the frequency conversion no negative pressure uninterrupted pipeline automatic pressurization water equipment. The equipment is widely used in all kinds of buildings, waterworks, mineral&industrial enterprise of pollution-free two water supplies.


VSNS no-negative pressure water supply system consists of 4 sub-systems:

Municipal Network Protection System, Pressure testing and pressure-stabilizing system, Pressurization system, Intelligent Control System.

1)      Municipal Network Protection System: consists of steady flow regulation tank, backflow preventer, municipal network protector, which can be directly connected with municipal network, without negative pressure.

2)      Pressure testing and pressure-stabilizing system: Pressure digital meter.

3)      Pressurization system: consists of vertical multistage pumps, pipes and valves. The pump group is the vital parts of the equipment.

4)      Intelligent Control System: consists of Touch Screen Control Panel, Converter, Programmable Controller etc, which is a special KY-Window software designed by our technicians.


1)      Water supply for Newly-built high building, office, hotels and School etc.
2)      Fire water supply when the pressure is too low from the running water.
3)      Living and production water and water circulation system in mining area and factories.
4)      Pressurization station in running water system
5)      Substitute of Air pressure water equipment, water pool, and water tanks.
