Non-Negative Pressure Booster Water Supply System For Water Filtration
The Pipe Network Superimposed Water Supply Equipment (Non-Negative Pressure Water Supply System) is an intelligent pressure-boosting device designed to connect directly to the municipal water network. It utilizes the existing pipeline pressure and automatically supplements it when needed, ensuring continuous and stable water supply without generating negative pressure — ideal for water purification and clean water distribution systems.
Pressure sensors continuously monitor both inlet and outlet pressures. The variable frequency controller adjusts the pump speed according to water demand, maintaining constant outlet pressure. When municipal pressure is sufficient, pumps slow down or stop to save energy. When pressure drops, pumps automatically start to compensate, preventing negative pressure and ensuring uninterrupted, safe water supply.
Variable frequency control system (PLC + pressure sensors)
Multi-stage centrifugal pumps (stainless steel)
Steady flow tank and check valve assembly
Negative pressure prevention and air release device
