Over fire facilities are used two system

1) For power plants in water cannons to hose types UNI 25/45/70 provided by UNI 10779.
2) For fi xed plants with oprimkler by UNI 9489.

For both systems is a group pumping RULES EN 12845 whose characteristics, fl ow and
pressure are measured by the designer.

Fire system EN 12845 can be trained by: Groups to one or more pumps to power that can be built with one pump as total reserves.
Groups with pump one pumps one diesel pump starts in case of lack of electric power.
These are the groups that provide the bulk. To work with the most economically sound solution. Groups to power more motogeneratore motor diesel especially in cases where Various reasons are used submersible pumps and a guarantee of continuous operation also Lack of energy.

All groups include the use of a pump compensation, wich is responsible for maintaining pressure. The installation in pressure automatically compensating the loss of any small.
