The portable fire fighting pump is an integral part of water-based fire suppression systems. Fire pumps are designed to increase the pressure (measured in psi and bar) of an existing water source to meet the hydraulic design requirements for a fire protection system. They are usually used to provide higher-flow water sources with greater pressure for long-distance hose lays and/or to overcome elevation differences.
There are several different types of fire pumps to choose from for your application and needs. The type of fire pump your property requires will depend on your specific requirements and code compliance standards. Choosing the right pump will ensure your water-based fire protection system will be able to operate at its full potential, meeting all NFPA regulations and ensuring safety for your property and its residents.
When selecting a portable fire fighting pump for your building, the most important consideration is the type of pressure and flow you require. There are two basic types of fire pump: centrifugal and positive displacement. Centrifugal fire pumps utilize a suction inlet and an impeller to generate pressure. The spinning action of the impeller creates high-pressure water by drawing water inward into its center and then outward to the discharge nozzle, which is attached directly to the pump outlet. These pumps are the most common for use with water-based fire systems.
Positive displacement fire pumps have a piston or plunger that moves inside the pump’s casing. The movement of the piston or plunger generates water pressure by pushing against the pump’s cylinder walls. These pumps are less expensive and easier to maintain than centrifugal fire pumps because the pump is easier to disassemble for inspection and maintenance. However, they may not be as efficient as centrifugal fire pumps when it comes to delivering water at high-pressure levels.
A portable fire pump must be rated to meet specific pressure and flow ratings, which can vary between different types of fire pump and between manufacturers. It is important to review the UL listing and NFPA regulations for each fire pump to be sure you are selecting a model that meets your specific needs and will operate effectively with your water-based fire suppression system.
