Product Description

The GEM, GEM.J and GEMK modular fire-fighting pressure boosters are built in conformity with EN 12845 for automatic
sprinkler systems and with UNI 10779 for hydrant systems. In accordance with the above standards, all the main components of
the single-pump booster set are factory connected and assembled. The configuration of the module, intended as a single unit,
always comprises the pump and varies according to the required type of motor or engine (electric or diesel). If modules are
combined, the water supplies described in EN12845 can be obtained for the fire-fighting system in question. These water
supplies can be single, superior, duplicated or combined.
Fire-fighting sets are generally fitted with two main service pumps, one backing up the other. The choice of electric motors or
diesel engines depends on the level of reliability required from the system. Point 10.2 of EN 12845 states that for superior or
duplicate water supplies, and if more than one pump is installed, no more than one service pump can be driven by the electric
motor. The pipe union of two modules is dimensioned considering only one pump in operation. In the case of three modules
tubing is dimensioned for two pumps in operation.
This concept means that most installations always comprise at least one diesel pump backing up the main electric pump.
The GEM fire-fighting sets are available in the following versions:

An electric service pump with hydraulic section and electric panel (GEM).

An electric service pump with electric jockey pump fitted on the base of the electric pump, a hydraulic section and
electric panels (GEM..J).

A diesel service pump with hydraulic section, electric panel and fuel tank (GEMK). The electric jockey pump is available
only as a kit.

The base module with GEMK diesel pump is completed with the following main components:
ENGINE PUMP
 On the discharge side of the service pump there is an on-off valve, a check valve and a tap for connection to the priming
MODULE
circuit for suction lift installations. Moreover, if the service pump works with a closed discharge line, a water recirculation
cycle is performed in order to prevent the pump from overheating.
 Two pressure switches for the service pump (if the first fails, the second repeats permission for the pump to start).
 System connection via a "T" pipe threaded or flanged.
 Single base to which the service pump is fitted.
 Electric panel attached to the fuel tank with possibility of wall-mounting.
 Fuel tank and relative fittings. The tank is sufficiently large to guarantee autonomy as per standard EN12845. Additional tank
and the fuel discharge valve of the main tank are provided on request.
 Starting batteries.
 Couplings for versions of the engine cooling circuit with water-cooled (WC) water to water heat exchanger.
No suction manifold is provided with the set, as standard EN 12845 provides for the use of independent suctions for each
pump.
