Design Pressure-boosting systems for firefighting in accordance with EN 12845:2015 + A1:2019. Depending on the model, composed of 1 horizontal base plate pump – EN 733 – with spacer coupling or cardanic joint, electrical or diesel motor and electrical multistage vertical jockey pump. Application Fully automatic water supply for fire-fighting systems with sprinklers in residential, commercial and public buildings, hotels, hospitals, department stores, and for office or industrial buildings. Equipment/function - 1 horizontal base plate pump per system from 32-200 to 100-200 series, with IE3 equivalent standard motor or diesel engine. - Diaphragm, to avoid over heating at zero flow, directly installed on the main pump housing. - Jockey pump from Medana CV1-L series - One controller fixed on robust supports. Model E for electric motor and D for diesel engine, both equipped with a firefighing dedicated controller, plus additional control J for jockey pump, if present. - Electro galvanised steel base frame. - Pipe work made of steel and epoxy painted. Manifold with flanges. - Shut-off butterfly valve with security lock on discharge side of each pump. - Non-return valve, on discharge side of each pump. - One circuit with double pressure switch, manometer, non return valve, valve, for main pump for automatic start. - Concentric cone on discharge side on main pump, for speed limitation according to prameters requested in EN 12845:2015 + A1:2019 standard. - Connection DN 2" for the priming tank per pump. - Pressure gauge on discharge side. - Only for diesel engine model: - 2 batteries on the base plate and battery chargers in the control box. - Separated fuel tank with level sensor and adequate volume to allow 6 hours operating autonomy. - Accessories on request: - Horizontal priming tank 500 L, with floating valve and pressure switch for low level alarm. - Flow meter - Kit eccentric cone on suction side complete of butterfly valve with hand lever or hand wheel. - Vacuum gauge with valve - Valves with electrical contact - Antivibration sleeve for manifold - Remote panel to transfer alarms level A+B - Densimeter for battery - Spare part kit for diesel engine - Silencer (30 dBA) for diesel engine - Hydraulic heat exchanger for diesel engine Technical data Allowed fluid: - Non-aggressive clean water, free of abrasive or long fiber substancesApplication field: - Power supply 3~400 V, 50 Hz (1~230 V, 50 Hz for Jockey pump and Diesel pump control panel) - Fluid temperature max. +25 °C - Ambiant temperature min/max. +4 to +40 °C (+10 to +40 °C if diesel pump is installed) - Maximum operating pressure 16 bar (12 bar with Jockey pump) - Maximum inlet pressure 6 bar - Flow from 10 to 320 m³/h - Maximum head 95 mPump impellers: - Bronze for main horizontal base plate pump - Stainless steel for vertical multistage jockey pumpElectrical Motor: - IE3 standard motors - Maximum power 55 kW - Nominal speed 2900 rpm - IP55 ratingDiesel engine: - Direct injection or supercharged diesel motor with air or water cooling. - Maximum power 66 kW - Forced lubrification with gear pump and oil filter - Cooling depending on the power: Up to 17,7 kW with air flow, direct or with water in closed circuit with radiator. From 26,5 kW with heat exchanger water/water.Other: - Epoxy painted pipes and hydraulic connections - Discharge nominal connection diameters DN 50 until DN 150 - EN 1092, PN 16 - Suction nominal connection diameters DN 50 until DN 125 - EN 1092, PN 16 - IP rating for Control box: IP54 Materials For horizontal base plate pump - Impellers made of Bronze CuSn10 or CuAl10Fe5Ni5 - Wear rings made of AISI316L/1.4409 stainless steel - Pump housing made of cast iron EN-GJL-250 - Shaft made of AISI420/1.4021 stainless steelFor Jockey pump - Impellers made of AISI304/1.4301 stainless steel - Pump housing made of AISI304/1.4301 stainless steel - Shaft made of AISI304/1.4301 stainless steel - O-ring-seals made of EPDM Scope of delivery - Factory-mounted,…
