Product Description

EEJ Electric Fire Fighting System

The CHINHER EEJ Electric Fire Fighting System is a complete fire pump package consisting of two electric fire pumps (duty and standby) and one jockey pump, providing reliable pressure maintenance and emergency water supply for fire protection systems.

The jockey pump automatically maintains system pressure during standby operation, while the duty electric fire pump starts automatically when pressure drops due to fire demand. The standby electric fire pump serves as a backup to ensure uninterrupted system operation and maximum reliability.

Designed for commercial, industrial, and municipal fire protection applications, the EEJ system is factory-assembled with pumps, control panels, valves, piping, and a common base frame, reducing installation time and simplifying on-site commissioning.

CHINHER offers customized configurations, pump capacities, control systems, voltages, frequencies, and OEM & ODM manufacturing services to meet different international project requirements.

FAQ

What does EEJ stand for?

EEJ refers to a fire pump system consisting of two electric fire pumps (duty and standby) and one jockey pump for automatic pressure maintenance and reliable fire protection.

Why are two electric fire pumps used?

One pump operates as the primary fire pump, while the second serves as a standby unit to ensure uninterrupted operation if the duty pump is unavailable or under maintenance.

What is the function of the jockey pump?

The jockey pump maintains system pressure by compensating for minor pressure losses, preventing unnecessary operation of the main fire pumps.

Can the EEJ system be customized?

Yes. CHINHER offers customized pump models, capacities, controllers, voltages, frequencies, piping layouts, and base frames to meet different project requirements.

Which standards can the system comply with?

The EEJ system can be designed and manufactured according to customer specifications and applicable international fire protection standards, including NFPA requirements where requested.
