Product Overview
The W/W/-HY Fire Pressure Stabilizing Booster is a specialized pressure boosting and stabilization system designed for firefighting water supply applications, built in strict compliance with GB 6245-2006 and NFPA 20 standards. It is designed to address the issue of insufficient static pressure at the most unfavorable point in temporary high-pressure firefighting water supply systems, particularly when the elevated firefighting water tank cannot meet the required pressure.
Model Designation
Key Features
- The W/W/-HY Fire Pressure Stabilizing Booster uses high-efficiency and stable pumps to provide continuous water flow and pressure for the system.
- The unit adopts a modular design for easy installation and maintenance, ensuring the system operates efficiently and stably.
- Pneumatic pumps provide stable pressure output, suitable for low-maintenance and high-efficiency applications.
Engineering Summary

Operating Manual
I. Product Overview
This booster and pressure stabilization equipment is developed and designed based on the Ministry of Construction’s “Document [1996] 108” from August 1996, and complies with the specifications of 98S205 (formerly 98S176).
The equipment is specifically designed to address situations where the height of the elevated fire water tank in temporary high-pressure fire water systems does not meet the required conditions. It is a dedicated booster and pressure stabilization system for firefighting (hereinafter referred to as “the equipment”).
This equipment is suitable for fire hydrant water supply systems and wet automatic sprinkler systems in multi-story and high-rise building projects, as well as various fire-fighting and domestic water supply systems.
II. Equipment and Principle
The equipment consists of an SQL air pressure water tank, an XBD-GDL multi-stage fire hydrant pump, an electrical control box, instruments, pipeline accessories, and other components.
The design follows the technical standards of “Fire Protection Design Specification for Civil Buildings” GB50045-95 and the “Pressure Water Supply Design Specification” CECS76:95.
The working principle of the equipment is to control the water pump operation based on the set operating pressures P1, P2, Ps1, and Ps2, thereby achieving the functions of boosting and stabilizing pressure.
III.Pressure Control
The required fire-fighting pressure at the disadvantage point, P1, is calculated and set as the air pressure in the water tank, which is then used to calculate P2. The control of the steady pressure water pump’s operation is achieved by setting Ps1 and Ps2.
The calculation of the fire-fighting pressure P1 varies depending on different scenarios (such as the fire hydrant system or automatic sprinkler system) and includes factors such as pipeline pressure losses, local losses, and the pressure required at the water gun nozzle.
IV. Functions & Electrical Control
The equipment must ensure that the fire-fighting water supply system’s disadvantage point pressure remains at the required value, while ensuring that the air pressure water tank always holds enough fire-fighting water.
The electrical control system offers both automatic and manual functions, and it is connected to the fire control center or fire pump room, supporting alternating operation of two pressure stabilization pumps.
The electrical control system also features a maintenance mode, allowing the pump to switch to a backup pump in the event of a malfunction, ensuring the continuous operation of the equipment.
OEM & Custom
Chaodun Pump provides OEM & ODM customization for W-HY fire pressure stabilizing systems, including control cabinet design, tank capacity, and pump selection. Our equipment supports hydrant and sprinkler combined configurations, tested under GB50045-95 and CECS76:95 standards for superior performance and reliability.
