Construction EBITT AUED MGHE

EN12845 Fire pump stations constructed for feeding water to automatic fire fighting systems and units with hydrants and sprinklers.

Units are composed of 1 or 2 main pumps and one jockey pump set with which the system pressure level can be maintained without having to start the main pump(s).

Operation

The pumps start operating after a fall in the pressure level in the fire extinguishing system.

The first pump to be triggered is the jockey pump in the station.

If this pump cannot restore the pressure level, then the main pumps starts.

When there is more than one main pump, the pumps start in cascade sequence with the starting pressure switches set at different pressure levels.

The pressure switches of the main pumps are used for automatic starting as the pumps must be stopped manually as per EN12845 standards.

The test loop or recirculation diaphragm allows for operation of the main pumps also when the delivery port is closed (with no consumption of water in the system), avoiding overheating of the

water inside the pump body.

Weekly test system is included in fire pump stations.

The membrane type of expansion tank with the capacity of 24 liters-16 bar execution is being mounted in fire pump set for absorbtion of water hammer.

Pumps

Ebitt EL series of main pumps are being used. Horizontal, end-suction, single staged centrifugal pumps are being used in fire pump station.

Standard delivery is cast iron execution with mechanical sealing.

Optionally bronze fitted execution or soft gland packing sealings are being used.

Couplings of main pumps are;

1. Elastic couplings for electric driven sets (optionally spacer type couplings)
2. Universal joints-cardan shafts for diesel driven sets.

Jockey Pumps are;

MV series: Vertical, multi-staged, stainless steel constructed off-line centrifugal pumps.

XVM series: Vertical, multi-staged, stainless steel constructed inline centrifugal pumps.

All pumps are mechanical sealed.

The maximum pressure developed by the jockey pump is always greater than the pressure of the main pumps.

Jockey Pump Controller (DJ)

DJ is designed for controlling 1 jockey pump used.

This cabinet contains the electronic control card with microprocessor, for managing pump operation.

The microprocessor carries out continuous secure checks during all the various work phases of the pump and incorporates all necessary functions, thus reducing electrical and electronic components inside.

The pump starts automatically when reaches at upper pressure set value and stops also when there is no water in the suction.
