The type of pump that is best for fire protection depends on several factors such as the size of the building or area to be protected, the distance between the water source and the building, the required water flow rate, and the available power source. However, centrifugal pumps are commonly used for fire protection applications due to their high flow rates, easy maintenance, and reliability.
In addition to centrifugal pumps, fire protection systems may also use positive displacement pumps, such as rotary pumps or reciprocating pumps, which are better suited for lower flow rates and higher pressures. Ultimately, the choice of pump type should be made in consultation with a professional engineer or a fire protection specialist to ensure that the system meets the specific requirements of the building or area to be protected.
