Fire Pumps & Fire Water Supply
Fire pump packages, fire water supply, pump-room installation, commissioning, flow testing, maintenance and service.
The fire pump is critical equipment that provides the flow and pressure required by sprinkler and hydrant systems. Selecting a pump only by its catalogue flow rating is not sufficient. System demand, pump curve, water supply, suction conditions, driver power, controller and system pressure limits must be assessed together.
Fire Pump System Components
- Electric main fire pump
- Diesel fire pump
- Jockey pump
- Fire-pump controllers
- Suction and discharge headers
- Test line / flow-measurement arrangement
- Pressure gauges and monitoring devices
- Fuel, exhaust and ventilation requirements for diesel systems
Critical Pump-Selection Issues
- Actual hydraulic system demand
- Ability of the pump curve to satisfy the required duty point
- Water tank and suction conditions
- Net positive suction and cavitation risks
- Maximum system pressure
- Electrical-supply or diesel-redundancy approach
- Fire-pump-room access, drainage and ventilation
- Accessibility for testing and maintenance
Commissioning and Performance Testing
During commissioning, automatic-start conditions, jockey-pump pressure settings, main-pump starting, controller alarms, flow testing and system pressures are checked. Test results should be compared against both the pump performance curve and the hydraulic design demand.
Standards and Design References
Depending on the project, NFPA 20, EN 12845, BYKHY and relevant client or authority criteria may apply. Pump configuration and redundancy are determined by project requirements.
Service Area
From Yalova, DEMOFIRE provides fire-pump design support, installation, commissioning, testing, maintenance and service primarily across the Marmara Region, including Istanbul, Kocaeli and Bursa, and—depending on project scope—in Izmir and throughout Türkiye.
Frequently Asked Questions
Is choosing a higher-flow fire pump always safer?
No. The pump must satisfy the system demand without exceeding the maximum allowable pressure of the system and its components.
Should a fire pump be tested annually?
Inspection and test intervals are determined by the applicable standard, local requirements and the facility maintenance programme.
Is a diesel fire pump mandatory for every project?
No. Redundancy and pump configuration are selected according to the project requirements and design basis.
