SS304 SS316L Non Negative Constant Pressure Water Supply System Variable Frequency

Non-Negative Pressure Booster Water Supply System For Water Filtration

Product Overview

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.

Working Principle

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.

Main Components

• 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

• Stainless steel piping and support frame

• Electrical control cabinet with intelligent monitoring panel

Features

• Non-negative pressure operation: Prevents backflow and secondary contamination.

• Energy-saving: Automatically adjusts pump speed according to demand.

• Intelligent control: Constant pressure and automatic start-stop operation.

• Compact design: Modular skid-mounted structure for easy installation.

• Stable operation: Multi-pump redundancy ensures continuous water supply.

• Hygienic materials: All wetted parts made of food-grade stainless steel 304/316L.

Applications

Ideal for water purification systems, residential water supply, hospitals, schools, office buildings, industrial facilities, and circulating water reuse projects.

Optional Configurations
