The Role of Jockey Pumps in Fire Pump Systems

The diesel engine fire pump has automatic, manual and fault self-inspection functions. It can monitor the working status of the whole process, restore the fault start, automatic pre-lubrication and preheating automatic restart function, and make the equipment start safer and more reliable. It has the functions of central control room remote control, remote transmission control and field bus connection. The battery is fully automatic floating charging (constant current, constant voltage, trickle charging) mode to ensure that the battery is in a standby state at any time. The diesel engine fire pump is easy to use, equipped with remote transmission meters and meters, which can be connected to the control center as needed, easy to install and use, and easy to maintain.

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.

1. Electric pump, can use single stage pump, horizontal split case pump, end suction pump, multistage pump, material can be cast iron, stainless steel, and bronze impeller 
2. Diesel engine pump, with capacity and head equal to electric pump, with fuel tank, water tank，fan, control box
3. Jockey pump, horizontal or vertical, capacity will be small, but head should be higher than electric and diesel engine pump
4. Control panel: Auto Control of electric pump, diesel engine pump and Jockey Pump with overload, over current protection。
5. Accessories: check valve, gate valve, pressure vessel, generally 0.6mpa, 1.0mpa, 1.6mpa, Pressure Gauge, Pressure Sensor, Common Pipe for Suction and Discharge, Flexible Joints and Flanges, Common Base plant

When selecting a firefighting pump, factors such as the intended application (e.g., residential, industrial, wildland), required flow rate and pressure, available power source (e.g., gasoline, diesel, electric), portability, and budget should all be taken into account. Consulting with experts or fire safety professionals can help ensure you choose the right pump for your needs.

Diesel engine fire pump, as a fixed fire extinguishing equipment, has been widely used in fire diversion, especially in emergencies such as no power supply or abnormal power supply, it can also be equipped with other diesel engines as power engines according to the needs of users.

Safety precautions include de-energizing electrical systems before maintenance, providing proper ventilation in pump rooms, and following lockout/tagout procedures to prevent accidental startup.

DJ fire pump group is mainly composed of diesel engine and regulator pump, can be selected in the state of no power supply.

Fire pumps are mainly used for pressurized water delivery in firefighting system pipelines, and can also be used in industrial and urban water supply and drainage, high-rise building depressurized water delivery, long-distance water delivery, heating, bathrooms, boiler cold and warm water circulation pressurized air conditioning refrigeration system water delivery and equipment matching, etc.

Fire pumps work by drawing water from a water source (such as a dedicated water tank or municipal supply) and pressurizing it before delivering it to the fire sprinkler system or hose lines.

Diesel engine fire pump sets are used in fire hydrant fire extinguishing systems and automatic sprinkler fire extinguishing systems in fixed fire extinguishing systems of enterprises, institutions, engineering construction, high-rise buildings, etc. It can transport clear water below 90 °C without solid particles and has similar physical and chemical properties. The water-based medium can also be used for fire protection, domestic and production shared water supply systems and construction, municipal water supply and drainage, etc.

Fire pumps should be inspected and maintained in accordance with local regulations and standards, but typically, they should be inspected at least annually and undergo a more comprehensive test every three years.
