APPLICATIONSCurrently there are two different fire-fighting equipments: those for the supply of installations containing extinguishing elements through sprinkles (ROC), manufactured under the standard UNE-12.845, and those for fire hose reels (FHR) or standpost hydrants (CHE), manufactured under current standard UNE-23.500:2012 and UNE-23.500:2018In addition, the equipments can also be assembled under the Technical Regulation CEPREVEN RT2- ABA, valid for any possible extinguishing combination. Despite not being considered as a national mandatory rule, it was the normative model while there was not a
clear legislation in this sector.
COMPONENTSMain pump: must be activated in case of fire and can only be stopped manually. This pump must be capable to propel minimum 140% of the nominal flow at a pressure not lower than 70% of the nominal pressure.Booster pump: same hydraulic characteristics as the main pump, electrical or diesel, its installation is needed when a back-up power supply is demanded due to the installations characteristics.Jockey pump: it is used to keep the fire-fighting equipment pressurized, balancing out the possible leaks in the installation avoiding the start up of the main pump. It starts and stops through a signal from the pressure switch, adjusted between two pressure values.Electric control panels according to constructive standards for the start and control of the pumps.Check and shut-off valves in every pump.Wide size range of general discharge manifolds.Pressure switch for manoeuvre.Pressure switch and safety valve for carried escape.Galvanized sheet base plate.24 liters HASABOX changeable membrane tank, stamped at a pressure higher than the maximum pressure of the circuit.Glycerin manometer.Sample manifold with insertion flowmeter (optional).All equipments are provided assembled over base plates and in-factory electrically tested.
APPLICATIONSThe groups against fires supplied byhidrautica alsina, s.a. They can be equipped with a flow measurement system.
COMPOSITIONMethacrylate meter with full scale reading l/min.Small float built in stainless steel, AISI 316.Flanged section of pipe with minimum dimensions of 10 times the diameter of the collector, before the meter, and 5 times the diameter of the collector after it.Nota: The test manifold must be installed in a horizontal position, while the insertion flowmeter must be mounted, in an essential way, in a vertical position on the top of the manifold.
