WG non negative pressure (stacked) water supply equipment is a new type of non negative pressure water supply equipment developed by our company based on years of practical experience in water supply equipment development, production, installation, and service. This device has the advantages of smooth operation, low noise, obvious energy-saving effect, and high level of intelligence. At the same time, it makes the equipment more exquisite, without the need for underground water tanks or water tanks. This not only reduces the area of the pump room but also saves equipment investment, making it an ideal product for upgrading traditional frequency conversion secondary pressure equipment. The equipment is directly connected to the water supply network, creating a closed environment for the water supply system. All flow components are made of food grade stainless steel material, completely avoiding secondary pollution of water quality. At the same time, it has efficient energy conservation, stable pressure, and complete protection functions (short circuit, overcurrent, overvoltage, overheating, protection functions). It has human-machine visual interface information exchange function, simple and convenient operation, and can provide RS485 interface or other communication methods according to user requirements to provide remote monitoring function.

Pressure adjustment accuracy: s0.01Mpa
No negative pressure: A dedicated and independently developed anti vacuum suppression system ensures that the equipment is directly connected to the municipal water supply network for water intake and pressurized operation without causing negative pressure in the municipal water supply network.
Borrowing pressure (or stacking pressure): Fully utilize the pressure of the municipal tap water pipeline network and perform secondary pressurization on this basis. Save constant pressure: Run various program calculations to cope with various water usage situations, take three constant pressure measures, prevent overshoot, prevent pressure drop, and use pressure to increase energy. Conveyor detection, with accuracy reaching thousands of levels, accurate pressure collection, stability and anti-interference power outage
Continuous water supply: When the power supply line is cut off, the system achieves continuous water supply through the 747D bypass method. When the power is cut off, it automatically switches to municipal tap water pressure supply.
High degree of automation: The intelligent control system can achieve fully automatic control, with functions such as manual/automatic switching, timed rotation of pump high and low voltage protection, under phase and phase sequence protection, overload protection, overheating protection, water shortage protection, small flow shutdown pressure maintaining, and instantaneous tripping protection< br/> Safety and hygiene: All overflow components are made of 304 stainless steel material, which complies with national water hygiene standards;
Saving investment: No need to build water tanks or pools, reducing equipment footprint, real estate developers can fully utilize the saved land to improve property utilization.
Saving operating costs: The equipment is directly connected in series with the municipal water supply network, and the required pressure is added on the basis of the original network pressure. The amount of difference and compensation can fully utilize the residual pressure of the network. The equipment has lower power than ordinary water supply equipment, low operating energy consumption, and extremely significant energy-saving effects.
