Diesel engine fire pumps are relatively common in life, and their performance requirements are relatively high. In ordinary use, more attention should be paid to maintenance, so as to prolong the service life of the pump. Because diesel fire pumps are not omnipotent, there will be some problems in daily use, so when choosing equipment, we must pay attention to whether the quality of the equipment meets the national standards. As fire equipment, all kinds of equipment must be To ensure performance, avoid affecting use in disaster situations and delaying rescue.

The DJ Fire Pump Set is a combination system consisting of a diesel engine pump and a jockey pump, designed for fire safety in the construction and industrial sectors.

The size and capacity of a firefighting pump depend on factors such as the size of the area to be protected, the potential fire hazard, and the water supply available. Calculating factors such as flow rate, pressure requirements, and the distance water needs to be delivered can help determine the appropriate pump size and capacity.

The conventional electric pump is the main pump, the diesel engine pump is the backup pump, and the jockey pump plays a role in the stabilization of the whole system. When the electric pump fails or the mains is cut off, the control cabinet will receive the pressure gauge from the electric contact. When the signal comes, the diesel engine pump will be started within 5 seconds, and the rated working condition will be reached within 20 seconds to ensure the normal operation of the fire extinguishing work.

It shows the fire pump set being tested. We have a factory equipped with a testing center. Products will be tested before delivery.
