Horizontal Single Stage End Suction Fire Pump for EDJ Packaged Fire Pump System

Packaged Fire Pump System EDJ | NFPA20 Compliant Diesel + Electric

EDJ Packaged Fire Pump System consists of a main electric pump(driven by electric motor), standby diesel pump(driven by diesel engine), and a multistage jockey pump.Pumps are assembled with both discharge and suction manifolds, wired to the control system and mounted on a common steel. The product has a compact design and small footprint, saving space in the pump room. After simply connecting the water and power supplies on site, the unit is immediately operational. In addition to the standard design. It can also be adapted according to the on-site requirements of the pump room.

Application:

This fire pump set can be used for fire sprinkler system, fire hydrant system and automatic sprinkler system in factory, shopping mall, high rise buildings, airports, warehouses, ports and villas etc.
Suitable for data centers & server rooms, hospitals & healthcare facilities, oil & gas facilities and municipal fire protection systems.

-Can ensure maximum reliability, efficiency, and safety in critical firefighting operations.

Working Principle

The automatic working principle is as followed:

Generally, the pipeline network pressure is between P1 (low pressure set) and P2 (high pressure set). Due to leakage of pipeline network or other reasons, P2 slowly drops to P1. Daily, the jockey pump will run to maintain the pressure between P1 and P2, minimizing the main pump starts. The start and stop of jockey pump is controlled by the signal from the pressure switch or pressure transmitter on the pipeline.
When the water consumption increases,and jockey pump is not able to maintain the basicline pressure P1 and quickly drops to P3, the electric pump will automatically start. The electric fire pump is as main fire pump to supply water and automatically started by the digital signal(l/O) by the pressure switch,flowmeter, alarm valve, pressure gauge and other sensors on pipeline.
When electricity supply stops or electric fire pump fails to start,the pressure continues dropping, then the diesel engine pump will be automatically started and pressure rises to supply water. The electric pump or diesel pump must be manually stopped after manual judgment.
The diesel engine fire pump has both manual and automatic control mode. Manual control is used for equipment inspection,maintenance,and on-site operation. The automatic control mode is operated by the integrated control cabinet or fire control center.

System Configuration

The EDJ packaged fire pump set is built around four standard configurations. All configurations use a stainless-steel multistage jockey pump for pressure maintenance, and can be customised to the pump-room layout.

Configuration	Composition	Picture	Typical Application
TEDJ	1 electric fire pump + 1 diesel fire pump + 1 jockey pump		Standard dual-power configuration — maximum reliability (default)
TDJ	1 diesel fire pump + 1 jockey pump		Sites with unstable or no reliable mains power
TEJ	1 electric fire pump + 1 jockey pump		Sites with reliable mains power — economical option
TEEJ	2 electric fire pumps + 1 jockey pump		Duty/standby electric configuration, no diesel required

Selection Guide

· Provide your required flow, head (pressure), site power availability, pump-room layout and local fire codes — our engineers will recommend the most cost-effective configuration and model.

· Maximum reliability / risk of grid outage → choose TEDJ (electric + diesel + jockey).

· No reliable mains power, or prolonged outage risk → choose TDJ (diesel + jockey).

· Reliable mains power only, no diesel required → choose TEJ or TEEJ.

· Confirm suction/discharge manifold size with the flow rate (see Section 6.5) and choose the matching pump type: horizontal single-stage end suction or horizontal double-suction.

· Confirm fuel tank capacity (100–2000 L, standard 6-hour operation) and battery backup with the selected diesel model.

· Always confirm medium, ambient conditions, altitude and pump-room dimensions with our engineers for a final recommendation.

FAQs

Q1: What does “dual power” (electric + diesel) mean and why is it important?

The set is driven by both an electric motor and a diesel engine. The electric fire pump is the daily main pump; if the mains power fails or the electric pump cannot start, the diesel-engine pump starts automatically, so fire-water supply is never interrupted.
Q2: What standards do the fire pumps comply with?

All fire pumps and the packaged set are designed and rated to the Chinese national standard GB6245 and NFPA20, covering rated point, 1.5× flow point, shut-off point power and performance requirements.
Q3: What fuel tank and battery options are available?

Fuel tanks range from 100 to 2000 L with an oil gauge, and supply/return rubber hoses (3 m each) are included. The set is fitted with two maintenance-free batteries (1 duty + 1 standby).
Q4: How long can the set run on the diesel engine / fuel tank?

The factory-standard fuel tank is sized for 6 hours of continuous operation at rated conditions. Tank options range from 100 L to 2000 L; larger or custom tanks are available on reques
Q5: Are the sets tested before shipment?

Yes. The complete packaged system is fully performance-tested and system-run under ISO9001 factory conditions before shipment.
Q6: What is the warranty?

18months from the date of shipment or 12months from installation, whichever comes first
