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. This system utilizes the powerful power output of the diesel engine pump, ensuring reliable operation even in the event of a power outage.

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). This pump provides higher pressure water flow to sprinkler system risers and hose risers.

EEDJ fire pump set consists of two electric pumps + diesel pump + jockey pump, which is manufactured according to customer requirements. All fire pumps use ISW pumps. The advantages of this fire pump set are easy installation, high cost performance, and suitable for any fire fighting. In emergency situations, it is equipped with a diesel engine pump, which can run even when the power is cut off.

Yes, installing diesel fire pumps in different environments or applications may require special considerations to address factors such as ambient temperature, altitude, seismic activity, corrosive atmospheres, and specific regulatory requirements. For example, pumps installed in outdoor or exposed locations may require weatherproof enclosures or additional corrosion protection, while pumps installed in seismic zones may need to be anchored securely to withstand earthquakes.

1. The fire pump pump room should be located close to the water source.

2. The location should allow easy access for maintenance and repair.

3. The area should be well-ventilated and protected from extreme weather conditions.

4. The room should be suitable for operation and maintenance of the fire pump system.

5. The pump room should be protected from unauthorized access.

6. The area should not be subject to flooding.

The electric fire pump unit is driven by an electric motor and has many different structures such as horizontal and vertical.

The electric fire pump set has a small footprint, light weight, low noise, and good start-up and operation performance.

Although the electric fire pump set has the advantages of simple operation and maintenance, most of the design specifications of the fire protection system stipulate that when using the electric fire pump set, it should have the condition of dual-circuit power supply. And usually there should be a diesel engine fire pump set as a backup pump set.

In the fire fighting pipeline pump, according to the different installation methods can be divided into vertical fire pumps and horizontal fire pumps, many people have questions about these two common pumps, what is the difference between the two? Shanghai Xizhiquan will explain the difference between horizontal and vertical pumps.

Obviously, different installation methods take up different space. Vertical pipeline pumps are installed vertically, covering a relatively small area, and vertical fire pumps do not require a foundation, while horizontal fire pumps need to be equipped with a base.

According to the different structures of the two pumps, it can be concluded that there is also a certain difference in the ease of maintenance of the two types of fire fighting pipeline pumps. The impeller of the vertical fire pump needs to be dismantled from top to bottom, which makes maintenance more difficult; the horizontal fire pump only needs to have the inlet pipe removed so that the impeller can be overhauled, which is relatively simple.

Due to the different inlet and outlet pipe directions, the pipeline connection between vertical and horizontal is also different. As the vertical pump is a bottom-up structure, while the horizontal fire pump is longitudinally arranged on the base, so the motor of the vertical pump and the pump body are connected in the form of sub-mouth connection, while the horizontal pump needs to use couplings to connect with the motor, and the horizontal pipeline pump needs to be corrected regularly.
