Fire pump systems are used to meet the critical water flow and pressure calculated as a result of fire suppression system design.
They continuously deliver water at the required flow rate and pressure to all systems requiring pressurized water, such as sprinklers, fire cabinets, indoor and outdoor hydrant systems.
What are the Key Features that Differentiate Fire Pumps from Other Booster Pump Groups?
Unlike water booster pumps, fire pumps have horizontal parallel performance curves. (Flow-pressure optimization)
Fire pump systems consist of main pumps and jockey pumps. Main pumps are always provided with redundancy.
Measures are taken to ensure that fire pumps operate even in the worst-case scenarios of power outages.
Regular testing and maintenance of fire pumps are mandatory.
According to the Turkish Fire Protection Regulations and NFPA20, What are the Pump Selection Criteria?
The most important 3 factors to consider regarding fire pumps:
• The pressure obtained when the rated flow rate reaches 150% should not be less than 65% of the rated pressure.
• The pressure obtained against a closed valve (at 0% flow) should not exceed 140% of the rated pressure.
• The declared flow and pressure values (kW / hp) should be approved to ensure they meet the reference values and are produced according to their intended use.
• According to Suction Type and Physical Characteristics
• End-Suction Fire Pumps
• Horizontal Split Case Fire Pumps
• Vertical Turbine Fire Pumps
• Electric Motor Driven Fire Pumps
• Diesel Engine Driven Fire Pumps
• The most preferred design standards worldwide for these systems are NFPA20 and EN12845.
• Designs should be made according to the same standard covering all system and equipment types.
• It is crucial that fire pump systems are tested and approved by international accredited organizations such as UL, FM, and VdS.
• Fire pump systems include various auxiliary environmental equipment such as relief valves, waste cones, flow meters, pressure gauges, vacuum gauges, test valves, etc.
• The type and specifications of these environmental equipment are determined based on the flow and pressure values of the main pumps (primary and backup).
