Product Overview

The Skid-Mounted Fire Pump Unit is a fully integrated, modular fire protection system designed to deliver reliable fire water supply under all conditions. The unit combines an electric fire pump, a diesel engine-driven fire pump, a jockey pump (pressure stabilizing pump), a pressure tank, a sophisticated control system, valves, piping and instrumentation into a single pre-assembled skid.

Under normal conditions, the jockey pump maintains system pressure. In the event of a fire, if the electric power supply fails, the diesel fire pump automatically starts to provide continuous flow and pressure, ensuring the fire protection system remains operational. Depending on regional terminology, it may also be referred to as a Modular Fire Pump Package, Integrated Fire Pump Set or Skid-Mounted Fire Pump Unit.

Key Features

• Fully integrated modular design combining electric, diesel and jockey pumps with control system
• Neat and standardised piping layout for easy inspection, operation and maintenance
• Modularised complete unit delivery simplifies on-site assembly and shortens construction period
• Clear pipeline interfaces and power connections for rapid integration with existing fire networks
• High automation level with automatic monitoring, start/stop control and status display
• Dual power source (electric + diesel) ensures fire water supply reliability during power outages

Applications

• Fire hydrant fire suppression systems in commercial and industrial buildings
• Automatic sprinkler fire protection systems
• Water mist fire suppression systems
• Fire protection water supply for high-rise residential and office complexes
• Industrial facility fire protection including factories and warehouses
• Hotel, hospital and commercial building fire hydrant and sprinkler systems

Customer Benefits

Reliable Dual-Power Backup

The combination of electric and diesel pumps ensures that fire protection water supply remains available even during total electrical power failures, providing critical backup capability during fire emergencies.

Space-Saving Integrated Design

The skid-mounted modular configuration integrates all components into a compact footprint, reducing the pump room space requirement compared to traditional scattered component installations.

Rapid On-Site Installation

The modularised pre-assembled delivery means minimal on-site assembly work is required. Clear interface connections allow for rapid integration with the building fire network, significantly reducing installation time and construction costs.

High Automation and Reliability

The advanced control system provides automatic pressure monitoring, pump start/stop sequencing and real-time status display, ensuring rapid response during fire events and reducing the need for manual intervention.

Neat and Maintainable Layout

The standardised piping layout and accessible component arrangement simplify routine inspection, testing and maintenance procedures, reducing downtime and maintenance costs over the system lifetime.

Comprehensive System Coverage

With flow rates up to 350 L/s and heads up to 240 m, the skid-mounted unit covers a wide range of fire protection requirements from small commercial buildings to large industrial facilities.

Selection Guidance

To select the appropriate skid-mounted fire pump unit, please provide the following information:

• Required flow rate (L/s)
• Required head (m) or pressure (MPa/bar)
• Fire protection system type (hydrant, sprinkler, water mist)
• Building type and occupancy classification
• Available installation space and pump room dimensions
• Available voltage and frequency for electric pump
• Local fuel supply and storage requirements for diesel pump
• Applicable fire protection standards and codes

Final model selection should be confirmed according to the actual duty point, system requirements and applicable fire protection standards.

Installation and Maintenance

Installation Guidance

The skid-mounted unit should be installed on a level, rigid foundation with adequate clearance for inspection, maintenance and diesel engine ventilation. The discharge connection must be aligned with the building fire network piping. A properly sized fuel tank with adequate fuel reserve must be provided for the diesel pump.

Pre-Commissioning Inspection

Before commissioning, confirm the following:

• Unit is securely mounted and level
• Discharge piping connection to fire network is complete and leak-free
• Fuel tank is filled with the correct grade of diesel fuel
• Engine coolant and lubricating oil levels are correct
• Starting batteries are charged and connections are secure
• Control panel wiring and settings are verified
• Valve positions are correctly set for normal operation

Routine Maintenance

Regular inspection should include:

• Weekly no-load test run of the diesel pump
• Monthly load test under fire protection system conditions
• Checking engine oil, coolant and fuel levels
• Inspecting batteries and charging system condition
• Verifying that the unit maintains the required flow and pressure during test runs
• Inspecting all pipeline connections and valves for signs of leakage

Available Configurations

• Flow rates from 10 to 350 L/s
• Heads from 30 to 240 m
• Motor powers from 7.5 to 1000 kW
• Electric pump + Diesel pump + Jockey pump combinations
• Integrated control panels with automatic start and monitoring
• Customised skid layouts for specific project requirements
