Many people buy fire pumps for the first time and don’t know how to choose a fire pump. They know very little about fire pumps and don’t know how to choose. So today, on the issue of fire pump selection, here is a explanation for everyone to help you better choose a more competitive fire pump.

Diesel engine fire pump is a common fire fighting equipment, especially suitable for use in places without electricity supply. The diesel engine fire pump uses a diesel engine as a power source to convert the work of the pump into hydraulic power to achieve a certain flow and pressure. It is mainly used in building fire protection, engineering fire protection, water source fire extinguishing and other fields.

With the continuous progress of the times, the application of diesel engine fire pumps is becoming more and more extensive. Diesel engine fire pump is a common and necessary facility. Only when the fire signal comes, and the electric water pump fails or the power supply is cut off, the diesel engine fire pump will automatically start. Diesel engine fire pump is installed together with electrical instruments, with complete functions, compact structure, automatic fault alarm, receiving start signal, and can automatically complete the start-up procedure and fast full-load operation. , Enough to ensure that the diesel engine fire pump is started in a low temperature environment, the whole system of the diesel engine fire pump is safe, reliable, and easy to use.

The diesel engine fire pump needs to be aimed at the occasion of large flow and high head fire water material supply, and it has good characteristics of the starting system for diesel automobile engines, fast starting development speed, strong overload capacity, no need for standby operation, and effective energy saving. Diesel engine firefighting pumps have complete performance and a wide range. Single-stage single-suction pumps, multi-stage single-suction pumps, self-priming pumps, long-axis pumps and other pumps can be used, and they can also be used in combination and in parallel. The flow and pressure ranges are wide. Diesel fire-fighting pumps are widely used in fire-fighting system water supply in various occasions of industrial and mining production enterprises such as data warehouses, docks, airports, petrochemicals, and power plants.

1. Good sealing performance: The mechanical seal of the fire pump has a good sealing performance and can effectively prevent the leakage of liquid.

This is a set of EDJ fire pump set, which consists of electric pump + diesel pump + jockey pump. The three pumps are automatically started and stopped. When the joceky pump detects that the electric pump cannot operate normally, the diesel engine pump will start automatically. Can also be used, the fire pump set is widely used in various emergency firefighting occasions.

1. Disconnect all electrical power to the fire pump and diesel engine.

2. Remove the fire pump and diesel engine from the mounting surface.

3. Drain the fuel from the fuel tank and disconnect the fuel lines from the engine.

4. Remove the hoses from the pump and the engine and drain the cooling system.

5. Remove the drive belt from the pulleys and remove the pulleys from the engine.

6. Remove the fan, flywheel, and starter motor from the engine.

7. Remove the cylinder head, piston rings, and other components from the engine.

8. Separate the pump from the engine and remove the impeller from the pump.

9. Disassemble the pump and engine into individual components.

10. Clean and inspect all parts for wear and damage.

11. Reassemble the pump and engine and reinstall on the mounting surface.

12. Reconnect the fuel lines and hoses and refill the cooling system.

13. Reconnect all electrical power to the fire pump and diesel engine.

The diesel engine (can be equipped with a clutch) is combined with the fire pump through a highly elastic coupling to form a fire pump unit. The unit also includes diesel tanks, cooling water tanks, fans, control panels (for automatic units) and other components.
When the unit is automatically controlled, the split or diesel engine automatic control cabinet (programmable) realizes the automatic start, input, and automatic switching of the system (switching from the electric pump group to the diesel engine pump group or from this group of diesel engine pump groups to another group of diesel engines) pump set), automatic protection (diesel engine overspeed, low oil pressure, high water temperature, three start failures, low oil level, low battery voltage and other alarm shutdown protection) and other functions, and can also interface with the user’s fire center or automatic fire alarm device, Realize remote monitoring.

The diesel engine fire pump is suitable for unattended emergency water supply systems. The product has the characteristics of good technology, high degree of automation, superior performance, complete protection functions, reasonable structure, simple installation, and high cost performance. pipe network pressure.

This group of fire pumps consists of two electric pumps + one jockey pump, and the motors are connected to multistage pumps.

A single-stage fire pump has only one impeller, and a multistage fire pump can have two or more impellers, which can achieve a larger lift at the same flow rate. Generally, it can be used as an industrial pump, a domestic pump and a fire pump.

Fire pump package comprises a combination of electric motor driven pump, diesel engine driven and electric motor driven jockey pumps that supply for fire suppression systems.
Fire pump package is required to comply with Local Civil Defense Authority regulations and International Codes of Practice e.g. National Fire Protection Association (NFPA).

Flow 200-2000 GPM
Rated pressure: 103-224 PSI
Speed： 2950-3550 RPM (50hz or 60hz)
Maximum working pressure: 280 PSI

The electric pump of the EDJ fire pump group 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 electricity from the The signal from the contact pressure gauge will start the diesel engine pump within 5 seconds, and reach the rated working condition within 20 seconds to ensure the normal operation of the fire extinguishing work.

Fire water pump refers to the water supply pump used to ensure the system pressure and water volume in the fire water supply system. The fire pump transfers energy to the water through the rotation of the impeller, thereby increasing the kinetic energy and pressure energy of the water, and transporting it to the fire extinguishing equipment to meet the water volume and water pressure requirements of various fire extinguishing equipment. Such as fire hydrant pumps, sprinkler pumps, fire transfer pumps, etc.

The fire pump is part of the water supply of the fire sprinkler system and can be powered by electricity or diesel. The inlet of the pump is connected either to a public groundwater supply or to a static water source (e.g. tank, reservoir, lake). The pump supplies water at higher pressure to the sprinkler system risers and hose risers.
Fire pumps generally use three driving forces, including diesel engines, gasoline engines and electric motors. Gasoline engines are commonly used in portable fire pumps and light duty firefighting. Electric motors are the most widely used driving force for fire pumps and are both efficient and convenient.

The diesel engine fire pump is suitable for unattended emergency water supply systems. The product has the characteristics of good technology, high degree of automation, superior performance, complete protection functions, reasonable structure, simple installation, and high cost performance. pipe network pressure.
