Are there specific regulations governing fire pump installation and operation?

While fire pumps are designed to run for extended periods during emergencies, continuous operation under normal conditions is not recommended. Prolonged operation can lead to wear and tear, and regular testing is preferred over continuous running.

The diesel engine fire pump unit is directly driven by the diesel engine fire pump, and it is a mechatronic equipment that can start and complete the water supply in a short time. The diesel engine pump set is driven by a diesel engine without external power supply. Diesel pumps are suitable for fire water supply occasions such as agricultural irrigation, emergency rescue, smelting, hangars, petrochemical oil depots, power plants, liquefied gas stations, and textiles. Especially in the case of no electricity and dissatisfaction with the grid, choosing a diesel engine-driven water pump is the safest choice.

The EJ Pump Set is designed according to the customer’s specifications which is including 1 electric pumps, 1 jockey pump and 1 control panel.

The conventional electric pump is the main pump, the diesel engine pump is the backup pump, and the voltage stabilizer 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.

This pump machine unit is very sutitable for fire fighting or pressure-stablized purpose for house or small building. We make it as customized according to NFPA 20 and GB standard.

1. The performance of the fire pump should meet the flow and pressure requirements of the fire water supply system.
2. The power of the driver equipped with the fire pump should meet the requirements of the power required for operation at any point on the performance curve of the selected pump’s flow and lift.
3. When a motor-driven fire pump is used, a dry-installed fire pump with the motor should be selected.
4. The fire pump should be installed dry, and the pump should be placed outside the pool, and the submersible pump cannot be directly placed in the water for water absorption.

Fire pumps are part of the water supply to a fire sprinkler system and are powered by electricity, diesel or steam. The pump inlet is either connected to a public groundwater supply or to a static water source (e.g. tank, reservoir, lake).

Diesel engine fire pump sets are mainly suitable for fire water supply systems in petrochemical, natural gas, power generation, cotton and linen textiles, warehouses, airports, docks, high-rise buildings and other industries. It can also be used in occasions such as water ships, offshore oil tankers and fire fighting ships. The unit adopts imported diesel engine and fire pump. It has the characteristics of quick start, reliable water diversion, reasonable power reserve, stable operation, wide range of pressure and flow, etc. It is an advanced and reliable fire-fighting equipment.

Pressure:2-20 BAR (30-290 PSI)

DJ fire pump set is suitable for fire protection occasions such as warehouses, docks, airports, petrochemicals, power plants, liquefied gas, textiles, ships, oil tankers, etc.

Prior to installation, fire sprinkler systems are hydraulically calculated to ensure adequate water flow and that the system can reliably suppress a fire until fire crews arrive. When it is determined that there is insufficient flow from a municipal supply for the system to function properly, a fire pump is installed. The fire pump activates when the sprinkler system pressure falls below a certain threshold as a result of sprinkler head operation. To maintain the required operating pressure of the sprinkler system, the fire pump draws additional water from the municipal water supply or on-site storage tanks. Due to the size of piping systems and pressure loss, fire pumps are frequently required in high rise construction and large area buildings.
