Fire Electric & Jockey Pump

Specifications

1. Electric Fire Pump
   • Power Source: Electric motor-driven, typically operating on a 3-phase electric supply. It ensures constant water flow at high pressure to feed sprinklers, hydrants, and other fire suppression systems.
   • Flow Rate: Available in various flow rates, ranging from 500 L/min to 5000 L/min (or more) depending on the system requirements. It is designed to deliver large volumes of water during fire emergencies.
   • Pressure: Can handle high discharge pressures, typically ranging from 10 bar to 30 bar, depending on the fire suppression system’s demands.
   • Pump Type: Centrifugal pumps are the most common, offering high flow rates and efficiency.
   • Motor Specifications: The electric motor is typically rated between 7.5 kW to 200 kW depending on the size of the system and the required flow rate.
   • Compliance: Built to meet NFPA 20, ISO 9001, and other local and international fire safety standards.
   • Cooling: Features an air-cooled or water-cooled system to maintain optimal temperature for continuous operation.
2. Jockey Pump
   • Function: The jockey pump is designed to maintain the system pressure in the fire protection system. It ensures that the system stays pressurized at the correct level to prevent the main electric fire pump from starting unnecessarily. It also compensates for small water losses due to leaks or changes in the system.
   • Flow Rate: Typically much smaller than the electric fire pump, with flow rates ranging from 50 L/min to 500 L/min.
   • Pressure Maintenance: Operates at low pressure to maintain the required pressure levels, typically between 2 bar and 10 bar.
   • Motor Size: Usually powered by smaller motors, often between 1.5 kW to 7.5 kW, designed for continuous or intermittent operation.
   • Automatic Operation: Starts and stops automatically based on system pressure, ensuring the system remains pressurized without excessive wear on the larger electric pump.
3. Construction and Materials
   • Pump Casing: Made from durable materials such as cast iron or stainless steel, ensuring resistance to corrosion, heat, and pressure.
   • Impellers: Constructed from high-strength bronze or stainless steel to withstand continuous operation and wear.
   • Bearings: High-quality bearings for smooth operation and durability, often made of carbon steel or ceramic to handle the mechanical stresses of firefighting operations.
   • Seals: Mechanical seals to prevent leakage and ensure efficient operation.
4. Control Panel
   • Automatic Start/Stop: Both the electric fire pump and jockey pump are controlled by an integrated control panel, which monitors system pressure and triggers the pumps as needed.
   • Monitoring and Alarms: Features visual and audible alarms to notify of any faults, such as low pressure, motor failure, or power issues.
   • System Integration: The control panel integrates with the fire alarm system and building management system (BMS) for remote monitoring and control.
   • Emergency Shutdown: The system will automatically shut down if there is an issue with the electrical supply, overheating, or mechanical failure.
5. Power Supply and Backup
   • Reliable Power Source: Powered by a stable electric supply, with backup options such as generator power for continued operation during power outages.
   • Automatic Transfer Switch (ATS): If power fails, the ATS ensures that power is quickly redirected to a backup generator to keep the fire pump system operational.
   • Battery Backup: Some systems are equipped with battery backup for short-term operation in case of power interruptions.
6. Size and Mounting
   • Compact Design: Both the electric fire pump and jockey pump are designed for easy installation and space-efficient mounting, whether in a pump room or an enclosed fire safety cabinet.
   • Skid-Mounted Options: Available in skid-mounted designs for mobile or temporary installations.
   • Modular Design: Systems can be customized and scaled based on the specific needs of the building, from small residential complexes to large industrial facilities.
7. Maintenance and Serviceability
   • Easy Access for Maintenance: Both pumps are designed for easy routine maintenance, with easily accessible components such as filters, bearings, and seals.
   • Spare Parts Availability: Genuine spare parts are widely available for long-term maintenance and repairs.
   • Service Intervals: Regular inspection and servicing of the motor, impeller, seals, and control panel to ensure optimal performance.
8. Certification and Compliance
   • NFPA 20 Compliant: Ensures the fire pump system meets NFPA 20 standards for fire pump installations.
   • ISO 9001 Certified: Manufactured under quality management standards to ensure durability, efficiency, and safety.
   • Local Fire Codes: The system is built to meet local fire safety regulations, ensuring compliance with both national and international standards.
