Split Case EDJ Fire Pump Set

Product Description

The Split Case EDJ Fire Pump Set is a horizontal split case pump system designed for fire protection applications. The "EDJ" designation represents the integration of Electric Motor, Diesel Engine, and Jockey Pump into a single packaged fire pump unit. Each component plays a specific role: Electric Motor: Provides primary pumping operation under normal power supply. Diesel Engine: Offers backup operation in the event of power failure. Jockey Pump: Maintains system pressure to avoid unnecessary operation of the main pumps due to minor leaks or pressure drops. All components are pre-assembled on a common skid, making installation faster and easier for fire protection contractors.

Six reasons for choosing us

Product Advantages

Uninterrupted Fire Protection

Combining electric and diesel drivers offers a true fail-safe system. If the electric power supply fails during a fire emergency, the diesel engine automatically starts to continue pump operation. This redundancy is essential for mission-critical applications such as data centers, airports, chemical plants, and refineries.

High Efficiency and Performance

Split case fire pumps are known for their high efficiency at large capacities, typically ranging from 500 to 5000 GPM (or higher). The double-suction impeller design minimizes axial thrust and reduces mechanical stress on the bearings and shaft.

Reduced Maintenance and Downtime

The split casing simplifies access to the impeller, seals, and bearings without dismantling the entire pump or motor. This reduces service time and maintenance costs, helping facility teams maintain system uptime.

Product details

Electric Motor

Provides primary pumping operation under normal power supply.

Diesel Engine

Offers backup operation in the event of power failure.

Strong base

In the context of fire pump systems, a strong base refers to a robust, stable, and vibration-resistant foundation on which the pump set (including electric motor, diesel engine, jockey pump, and piping) is mounted.

Discharge

Discharge is the flow rate and pressure at which the fire pump pushes water out of the discharge port or flange after drawing it in from the suction side.
