Automated Electric Fire Pump Set for Optimized Fire Water Supply Pressure Control
The automated electric fire pump assembly integrates a main fire pump, a jockey pump, a control cabinet, and a pressure tank; it supports automatic pressure control and stable water supply, offers various configurations for flow rate, head, and pump type, and is suitable for fixed fire protection systems in building and industrial applications.
The automated electric fire pump set is a complete fire-fighting equipment package designed for fixed fire water supply systems. It primarily consists of an electric main fire pump, a jockey pump, an automatic control cabinet, a pressure tank, pressure gauges, pressure sensors, valves, and connecting piping; these components work in concert to manage fire water supply and pipeline network pressure. The equipment utilizes an integrated skid-mounted base that consolidates the main pump assembly and control components into a compact structure, thereby minimizing on-site piping connections and equipment layout work while facilitating transport, installation, and maintenance. The electric main fire pump handles the primary water supply during fire emergencies; pump types—such as end-suction, horizontal split-case, vertical split-case, vertical in-line, or multistage pumps—can be selected based on the specific flow and pressure requirements of the project, ensuring adaptability to varying building heights, pipeline distances, and water demand specifications. The system supports flow rates ranging from 14 to 2,700 GPM and heads of approximately 12 to 80 meters, with rotational speeds configurable between 740 and 2,900 rpm depending on the pump model; various capacity and pressure rating configurations are available. The jockey pump features a low-flow, high-head design that promptly compensates for pressure fluctuations or minor leaks in the fire network, maintaining the pressure within the set range and preventing unnecessary, frequent starts of the main fire pump. When a significant demand for fire water arises, the control system activates the main fire pump in response to pressure change signals, ensuring a continuous and stable flow and pressure for the network. The automatic control cabinet provides centralized control for both the main and jockey pumps and includes protective features against overload and overcurrent; it also integrates pressure sensors and gauges to monitor system pressure in real-time, enhancing automation and ease of use. Pressure tanks are available in specifications such as 25, 50, 75, and 100 liters to meet project needs, with pressure ratings configurable to 0.6, 1.0, or 1.6 MPa to match the pump head and network operating pressure. Regarding material specifications, the pump casing and wetted parts can be fabricated from cast iron, stainless steel, or bronze—selected based on the operating medium and environment—to ensure both mechanical strength and corrosion resistance. The system features an integrated piping and electrical control design that minimizes the equipment footprint within the pump room and simplifies pressure monitoring, pump control, and piping connections, thereby facilitating commissioning and operational management. This automated electric fire pump system is suitable for warehouses, docks, airports, petrochemical facilities, power plants, liquefied gas installations, textile mills, marine vessels, and other locations requiring a fixed fire-fighting water supply. Configurations for flow rate, head, pump type, pressure tank, and control method can be tailored to specific project conditions, ensuring a stable, rapid, and highly automated water supply for fire-fighting networks.
