DAB : FIRE-FIGTHING UNI 9490 - 10779

UNI 9490 - 10779 compliant booster units for automatic fire-fighting systems.The standard version comprises a diesel pump that can be coupled with one standardised electric pump, together with a compensation pump, if required JET.

OPERATION

The pilot pump (if fitted) starts whenever there is a pressure drop in the system.If this is insufficient to recover pressure, the primary electric pump starts (if the

unit comprises an electric pump and a diesel pump).A continuously charged battery and fuel tank ensure the diesel pump starts and operates in case of a power failure.

MAIN COMPONENTS

Hydraulic – mechanical part:-

Galvanised steel base for diesel pump, fitted with vibration-damping feet.

- Direct injection diesel engine allowing overloading up to 10% (UNI 94904.9.5.1.) connected with a flexible coupling to the standardised pump. The fuel tank is large enough to guarantee 6 hours of operation.

- Standardised primary pump base and pilot pump.

- Separate suction lines for each pump, complete with vacuum pressure gauge.

- Inspectable check valves, delivery shut-off valves and pressure gauges.

(*)Galvanised steel delivery manifolds with starting pressure switches and expansion tank.

(*)The two manifolds of the diesel pump assembly and the electric pump assembly can be joined together with a single manifold supplied with the unit.

Electrical part:

- Control panel for diesel pump with control unit, line isolator, voltmeters and ammeters, rev counter, hour counter, 2 battery changers for the two starting batteries

12, AUT-0-MAN selector, STOP button.

- Control panel for primary electric pump, complete with line isolator, starters(direct up to 7.5 kW - star-delta over 7.5 kW), voltmeter, ammeter, AUT-0-MAN

selector, STOP button. Connector for weekly test unit (only for the electric pump).

- Control panel for pilot pump with overload cut-out, line isolator and AUT-0-MAN selector.
