Product Introduction

Generally, a constant pressure variable frequency pump group is used for water supply, with at least two or more water supply pumps installed. Each pump can be controlled by a variable frequency converter according to the water consumption, with one in use and one backup or multiple in use and one backup, running in parallel, significantly saving electricity and effectively reducing water supply costs. The built-in variable frequency converter has a high degree of automation; The equipment is mainly composed of components such as a stabilizing tank, a water pump, and a control system. Low equipment investment, small footprint, flexibility, and convenience.

Technical Advantage
High Efficiency and Energy Saving
Save up to 30%-40% of electric energy
Food-grade material
All flow-through components are made of food-grade stainless steel, eliminating secondary contamination of water
safe and reliable
Anti-slip, anti-low water level, anti-freezing crack, anti-water hammer, anti-backflow, anti-current overload
Variable frequency constant voltage stability
By detecting the pressure at the water outlet through real-time sensors and utilizing frequency conversion control, the water pressure is ensured to remain constant
Process Selection

1. It adopts microcomputer control, operates fully automatically, and is easy to manage, use, and reliable.

2. Compact structure, small footprint, low investment, easy installation, and convenient centralized management.

3. Fully functional, it can achieve various functions required by users through panel operation.

4. According to the required pressure, adjust the speed of the motor pump based on changes in water consumption, ensuring the equipment supplies water at a constant pressure and achieving energy conservation.

5. It can reliably achieve soft start for multiple motor pumps, greatly extending the service life of the equipment.

6. Automatically complete the entire process of cyclic soft start and stop for multiple water pumps based on changes in flow.

7. Equipped with a small pressure water tank device, the system sends feedback to the controller via a remote pressure gauge, allowing the water pump to be stopped when there is low or zero flow, thereby further reducing energy consumption and extending the service life of the equipment.

8. Complete protection functions: undervoltage protection, overvoltage protection, overload protection, short circuit protection, stall prevention, etc.

9. Both the working pump and the standby pump feature periodic operation, automatic inspection, and manual inspection functions.


Equipment Selection

1. Common pump types and applications:

Multi stage centrifugal pump: used for secondary pressurization or long-distance transportation in high-rise buildings, capable of providing high head.

Double suction centrifugal pump: used in the water supply pump room of water plants, with high flow rate and high efficiency.

Submersible pump: used for water intake or underground lifting.

2. Key configuration:

Variable frequency speed regulation: By using PLC and pressure sensors to form a closed-loop control, constant pressure water supply is achieved, and the energy-saving effect is significant (after adopting it in a 60000 ton/day water plant, the power consumption per ton decreased by 20%).

Backup pump: must be set up to ensure continuous water supply.

Soft starter: reduces the current surge during motor start-up and the "water hammer" effect on the pipeline network
