Fire pumps, as the name suggests, are water pumps used in firefighting. They come in various types based on different classification methods. Known for their fully sealed, leak-proof, and corrosion-resistant features, they are widely applied in environmental protection, water treatment, and fire departments. These pumps are used to pump various liquids and are ideal for creating leak-proof, pollution-free civilized workshops and factories, as well as for fire protection systems. Fire pumps are specialized equipment for firefighting water supply, generating centrifugal force through the rotation of the impeller to convey liquids. They offer stable flow rates, high head, and high pressure resistance. Common materials include cast iron or stainless steel, with types such as horizontal and vertical designs. They must be used in conjunction with control systems and piping. Fire pumps are primarily applied in building fire protection, such as indoor and outdoor fire hydrant systems in malls and residential buildings, automatic sprinkler systems, and emergency fire water supply in special scenarios.
The selection of fire pumps should be based on the process flow and water supply and drainage requirements of the application project, taking into account five aspects: liquid delivery capacity, equipment head, liquid properties, pipeline layout, and operating conditions. Fire pumps are mainly divided into vertical and horizontal types. The flow rate of the liquid being delivered is one of the key performance parameters for selecting a fire pump; it directly affects the overall production capacity of the system. Regular testing of the start-up performance is essential to prevent long-term idling and clogging, while checking for wear on seals and bearings to avoid leakage or reduced efficiency.
The reliability and corresponding speed of the fire pump are directly related to the effect of fire fighting, so it is necessary to strictly follow the specifications in the design, installation and maintenance to ensure that it is always available.
