For example, if you have a 40,000-square-foot building that is all ordinary group 1, the calculation would be 1,500 x 0.15 (density) = 225 + 250 (hose demand) = 475 gpm total for the fire pump. If the structure has multiple hazards, the hazard with the highest gpm calculation dictates the pump size.
Which types of pumps used in fire fighting system?
Various types of fire pumps are used in fire protection systems. Types of fire pumps include: horizontal split case, vertical split case, vertical in-line, vertical turbine, and end suction. These fire pumps may be powered by an electric motor or diesel engine and on rare occasion powered by a steam turbine.

How do you calculate the flow rate of a fire pump?
The equation EP = NP + FL + APP + ELEV is the basic equation every pump operator needs to calculate when operating the fire pump. Today, many pump panels have flow meters that allow the pump operator to match the readout on the pump panel with the gallon-per-minute (gpm) flow of the selected nozzle.
Can you use a transfer pump for fire fighting?
Be wary of trash pumps or transfer pumps that you may find locally. These are not designed, tested or approved for fire fighting -- and do not provide the performance and reliability for safe, effective fire fighting operations.
Which pump is suitable for firefighting?
Centrifugal pumps
What is the difference between a fire pump and a jockey pump?
The jockey pump is designed to start before the main fire pump and return the fire protection system to its minimum static pressure. A jockey pump is not required on systems utilizing a fire pump, however, due to their relative simplicity, jockey pumps are the most common method used to maintain system pressure.
What is portable pump?
Pumps are essential firefighting equipment. With the optional extension, you can carry up to ten rolls of fire hose (1000') side by side or two five-gallon gas cans plus intake hose and a pump/hose fitting bag.
What is the purpose of a fire pump?
Fire pumps are an essential part of many water-based fire protection systems. They are used to increase the pressure (measured in psi and bar) of a water source when that source is not adequate for the system it's supplying.Apr 2, 2021
What is portable fire fighting equipment?
The most widely used type of fire extinguisher is the multipurpose dry chemical that is effective on Class A, B, and C fires. This agent also works by creating a barrier between the oxygen element and the fuel element on Class A fires. Ordinary dry chemical is for Class B and C fires only.
