Fire centrifugal electric water pump is a commonly used water pump in fire protection systems, which uses centrifugal force to transport and pressurize liquids, providing stable high-pressure water flow for fire extinguishing. Fire centrifugal water pumps are generally composed of components such as electric motors, pump bodies, impellers, and sealed bearings. The impeller is the core component that generates centrifugal force through rotation. The pump body is used to accommodate the impeller and water flow, and the sealing device prevents liquid leakage. The bearings support the rotation of the pump shaft. It has the characteristics of wide flow range, stable operation, relatively simple structure, and easy maintenance, which can meet the requirements of different fire scenarios for water volume and pressure. Therefore, the vast majority of fixed fire main pumps and stabilizing pumps use centrifugal pumps.
Fire centrifugal electric water pumps can be divided into single-stage centrifugal pumps and multi-stage centrifugal pumps according to their structure. Single stage centrifugal pumps have only one impeller, simple structure, and relatively low head, while multi-stage centrifugal pumps are composed of multiple impellers connected in series, which can generate higher head. According to the installation method, it can be divided into vertical centrifugal pumps and horizontal centrifugal pumps. Vertical centrifugal pumps have a small footprint and are suitable for places with limited space. Horizontal centrifugal pumps have good stability and are commonly used in large fire protection systems.
Common models include XBD, IS, etc. Different models of water pumps have different parameters such as flow rate, head, and power to meet the needs of various fire engineering projects.
