Product Advantages
1. High Efficiency and Energy Saving
The system adopts variable frequency control to automatically adjust pump speed according to actual water demand, reducing unnecessary energy consumption.
2. Stable Constant Pressure
Pressure sensors monitor pipeline pressure in real time, and the system automatically adjusts the operating status to maintain stable water supply pressure.
3. Intelligent Control
The system can realize automatic start and stop, multi-pump switching, fault protection, and operation monitoring, reducing the need for manual supervision.
4. Compact Structure
The pumps, control cabinet, pipelines, and pressure stabilizing components are integrated into one system, offering a small footprint and convenient installation and maintenance.

Installation Instructions
1.Before installation, check whether the equipment model, flow rate, pressure, power supply parameters, control mode, and installation dimensions meet project requirements.
2.The equipment should be installed on a flat, stable, and well-ventilated foundation, with sufficient space reserved for operation, maintenance, and heat dissipation.
3.Inlet and outlet pipelines, valves, pressure gauges, sensors, and electrical wiring should be connected according to the drawings to ensure reliable sealing and secure wiring.
4.Before commissioning, check the pump rotation direction, pipeline valve status, control cabinet parameters, pressure stabilizing tank pressure, and protection functions.
5.During initial operation, observe pressure changes, start-stop status, noise, vibration, temperature rise, and water leakage. The equipment can be put into normal operation after confirming that all conditions are normal.
Frequently Asked Questions
Selection should be based on design flow rate, required water pressure, building height, number of water points, inlet conditions, power supply parameters, and control requirements. Pump quantity, pump power, pressure stabilizing tank, and control cabinet configuration should then be matched accordingly.
Variable frequency constant pressure control automatically adjusts pump speed according to pipeline pressure changes, keeping system pressure within the set range while reducing frequent starts and stops and unnecessary energy consumption.
Yes. According to project requirements, the system can be designed with duty and standby pumps, multi-pump parallel operation, automatic pump rotation, variable frequency pump staging, and automatic fault switching.
Yes. It can be used to upgrade traditional water supply systems such as ground tanks, water tanks, roof tanks, or systems with insufficient municipal water pressure, improving water supply stability and automation.
Common causes include abnormal pressure sensor signals, improper control parameter settings, insufficient pressure stabilizing tank pressure, pipeline leakage, abnormal valve status, or a mismatch between pump selection and actual operating conditions.
Before operation, check power supply voltage, grounding, pipeline connections, valve status, pump rotation direction, control cabinet parameters, pressure sensor signals, and pressure stabilizing tank pressure. Start the system only after confirming that there are no abnormalities.
