The Constant Pressure Variable Frequency Water Supply System is an advanced intelligent water supply solution designed to maintain stable water pressure automatically through frequency conversion technology.
It integrates variable frequency drive (VFD), pressure sensors, intelligent control cabinet, and high-efficiency water pumps to ensure continuous, stable, and energy-saving water supply.
This system is widely used in residential buildings, industrial plants, hotels, hospitals, commercial complexes, and municipal water supply networks.
The system automatically adjusts pump speed according to real-time water demand, ensuring stable pressure output without fluctuation.
By using variable frequency control, energy consumption can be reduced by up to 30%–60% compared with traditional water supply systems.
PLC intelligent control system enables automatic start/stop, pressure adjustment, and fault protection.
Equipped with high-quality stainless steel pumps and advanced control components for long-term stable operation.
Compact structure design reduces installation space and simplifies maintenance requirements.
The complete system typically includes:
Variable Frequency Pump Unit
Intelligent Control Cabinet (PLC + VFD)
Pressure Sensors
Stainless Steel Pipeline System
Expansion Tank (optional)
Protection & Alarm System
The constant pressure water supply system is widely used in:
Residential apartment buildings
High-rise commercial buildings
Hotels and resorts
Hospitals and schools
Industrial manufacturing plants
Agricultural irrigation systems
Municipal water supply projects
The system monitors pipeline pressure in real time through sensors. When water demand increases, the frequency converter increases pump speed; when demand decreases, the system reduces pump speed accordingly.
This closed-loop control ensures:
Stable water pressure
Reduced energy consumption
Extended pump service life
Reduced mechanical wear
