KIT FFS SERIJOS

APPLICATIONS
The EBARA KIT FFS 11-21S type pressure boosting units are applied in the
automatic activation water supplies for the automatic fire fighting units
in compliance with European Standard UNI EN 12845

SPECIFICATIONS
As established by the UNI EN 12845 Standard, if the firefighting unit supply pumps intervene,
they are started by a pair of pressure switches via an electric control panel supplied with each pump and they must
function continuously until stopping, which only occurs with a manual control.
The start-up of the supply pumps can cause simultaneous activation of an acoustic and luminous long distance indicator.
The small flow rate jockey pump (pilot), intervenes in the case of small system leaks and is started and stopped automatically by its own electric control panel and relative pressure switch calibrated at a pressure value slightly higher than the pressure switch value of the supply pump. Stopping takes place when system pressure is resetd. The acoustic – luminous indicator also signals a missing phase, the voltage,lack of water and any incorrect position of the shut-off valves both in discharge and suction. The electric control panels are equipped with pump running signals.

TECHNICAL DETAILS
KIT FFS 11/21 S: unit made up from 1 or 2 main submersed electric pumps, vertical multistage and an electric jockey pump;The KIT FFS firefighting pressure boosting units can be used exclusively as envisioned in the UNI EN 12845 LH, OH, HH Standard, in the automatic activation water supplies for the automatic fire fighting units in civil and industrial activities. The water conveyed must not contain solid bodies and fibres in suspension or vegetation and without aggressive and corrosive chemical substances (UNI EN 12845 8.6).
• Minimum temperature of the water conveyed is 0°C, max
temperature 40°C (25°C for submersed multistage pumps)
• Environment functioning temperature is 4°÷40°C at a height not exceeding 1000 m a.s.l.
• Max. relative humidity 50% at +40°C
NB: possibly the pumping unit must be installed underhead (UNI EN 12845)
NB: each pump must have its own independent suction pipe (UNI EN 12845).
