They are pumps that provide pressurized water to water quenching systems and are expressed by nominal flow rate and rated pressure value. Pumps must not be less than 65% of the nominal discharge head, and the closed head (zero flow) head must be no more than 140% of the nominal head and 150% of the head. Such pumps can be used for system demands at 130% of the nominal flow rate, provided that the required pressure value is met.
If a pump is used in the system, it must be a spare pump in the same capacity. If there are more than one pump, enough spare pumps will be used provided that at least 50% of the total capacity is backed up. The pump can be rotated by an electric motor, that is, by internal combustion engines or turbines.
If a backup diesel pump is not used, the power supply of the fire pumps will be supplied from a reliable source and will be fed independently of the construction's general electrical system.
There must be auxiliary elements such as fire pumps, automatic air release valve, circulation relief valve. Each pump must have a separate control panel. The panel must be locked. The electrical control panel must be equipped with phase lights, phase-sequence fault, control phase fault, information lights. The on / off switch must not be accessed before the panel lock is opened.
Each pump must be a separate pressure switch. The pressure switches are located inside the control panel, the water pressure is protected by the pipe connection, protected against water hammer, the lower and upper values ​​can be set individually and independently and locked after set.
Pump control can be pressure controlled full (automatic start-stop) or semi-automatic (automatic start-stop manually).
Appropriate equipment will be provided to maintain the temperature continuously above + 4 ° C in the pump room or pump station.
Emergency lighting will be provided at the pump station around the working area of ​​the devices requiring service, inspection and adjustment.
The ground should be sloped for adequate drainage to ensure that water is removed from critical devices such as pumps, drivers, control panels.

Horizontal Split Body Pumps
Horizontally divisible body pumps are designed to provide all the features expected from a fire pump. It is composed of the components that can be designed and supplied with the standards (NFPA20) that can give the required pressure and flow in fire conditions. (UL and FM approved). They are manufactured at pressures between 300 GPM and 5000 GPM and pressures between 40 PSI and 545 PSI.

Suction Suction Pumps
It is designed for projects with lower pressure and flow requirements. They are manufactured at pressures between 25 GPM and 500 GPM and pressures between 40 PSI and 190 PSI.

Vertical Type Line Input Pumps
It is designed for projects requiring low pressure and flow, such as suction pumps. They are manufactured between 25 GPM and 500 GPM and at pressures between 40 PSI and 190 PSI.

Jockey Pumps
The fire extinguishing system is used to keep the pipeline under constant pressure and to prevent the main pumps from being switched on during the pressure drop caused by escape. They are manufactured at pressures between 5 GPM and 75 GPM and pressures between 40 PSI and 190 PSI.
