The electric fire pump is manufactured with good structure and workmanship. It has a wide range of performance, and is easy to use and operate for a long time. The electric fire pump is aimed at various fire water environments, so the selection should also be based on the actual demand environment, performance parameters, etc.

As the name implies, fire pumps are classified into different types according to different classification methods, and are widely used in environmental protection, water treatment, fire protection and other departments because of their fully sealed, leak-free, and corrosion-resistant characteristics. liquid-like. The pump types are similar, but the head and flow are different. The selection basis of the fire pump should be considered according to the process flow, water supply and drainage requirements, and other five aspects.

A multistage pump is a multistage centrifugal pump in which two or more impellers are installed on the pump shaft and connected in series to work together. A horizontal multistage centrifugal pump refers to a multistage pump in which centrifugal pumps with two or more impellers are combined.

Key components include the pump itself, the engine or motor, an intake system, a discharge system, and various safety features such as pressure relief valves.

Horizontal and vertical fire pumps differ in their physical orientation, and the choice between them depends on the available space and installation requirements. Horizontal fire pumps are positioned parallel to the ground and are commonly used in facilities with ample floor space. Vertical fire pumps, on the other hand, are designed to be installed in a space-saving, vertical orientation. This makes them suitable for facilities with limited floor space, such as high-rise buildings.

Vertical pumps are often used in skyscrapers, where space is at a premium. Both types of pumps are equally effective, and the choice between them is typically influenced by the layout and structural constraints of the building.
