Types of system pumps:- Three pumps are installed on the main line of the system, as follows: Electrical Pump It is often a separate type horizontal or peripheral suction pump. Diesel Pump It works if the electric current is cut off from the building or if the electric pump fails to provide pressure due to the excessive load on the electric pump Jocking Pump It is small in size as a separate pump type, horizontal or multi-stage, and gives a flow of 10% to 15% of the flow of the fire network. Its purpose is to compensate for any loss in the network as a result of a leak in the system network or a decrease in pressure with which the main fire pump operates. ya (extra load on it) and thus may lead to its combustion. Therefore, an auxiliary pump is installed to compensate for this deficiency. Fire pump specifications: The components of the pumps must be made according to the approved international specifications such as BS or British specifications or the American ANSI. VLC, FM or UL international accredited bodies, such as stating that the pump has been tested with its electrical panels according to the required conditions and specifications

The thickness of the pump must not be less than 10 mm for large pumps and 8 mm for small pumps, and it must be made of cast iron or cast steel according to the approved specifications. * The capacity of the fire pump must be less than 1892 liters / minute

* The drive shaft of the pump must be made of stainless steel and its resistance to high voltage

* Sometimes firefighting systems are provided with backup pumps, and an auxiliary pump (its capacity is not less than 5% of the main pump capacity) is provided to cover any expected leakage within 10 minutes.

* Bases must be provided for the pumps commensurate with their weight, according to the manufacturer’s instructions, in order to protect them from vibrations and mechanical factors.

* Protection covers must be provided for the rotating parts of the pumps.
