EDJ fire pump set (Electric pump+Diesel pump+Jockey pump)

An EDJ fire pump set typically refers to a system used in fire protection and suppression applications. This system combines three different pumps to ensure a reliable and efficient water supply for fire sprinkler systems:

Electric Fire Pump: This is the primary pump used to supply water to the fire protection system. It is powered by electricity and provides a steady flow of water to the sprinklers when a fire is detected. Electric fire pumps are often the first choice for supplying water because they are reliable and can provide a continuous water source.

Diesel Fire Pump: The diesel fire pump serves as a backup or secondary water supply in case of an electrical power failure. It operates independently from the electric pump and is driven by a diesel engine. These pumps are crucial in situations where power may be lost during a fire emergency.

Jockey Pump: The jockey pump is a smaller pump designed to maintain the pressure within the fire protection system. It is responsible for keeping the system pressurized at all times, even when there are no active fire events. The jockey pump operates quietly and continuously to ensure that the system is ready for immediate use when a fire is detected.
