It draws water through a large pre-filter basket and sends it to the filter. It is installed in the plant room, below or above the pool water level.\u003c\/p\u003e\n\u003ch3\u003eWhat problem does it solve?\u003c\/h3\u003e\n\u003cp\u003eA public pool has to turn over its whole volume in a few hours, and the pump runs almost without a break. With a 2,850 rpm motor the noise carries into the pool hall and the rooms next door, and wear arrives sooner.\u003c\/p\u003e\n\u003cp\u003eA pump short on flow forces longer filtration cycles and pushes up the electricity bill; an oversized one punishes the filter. The Magnus covers 32 to 177 m³ per hour at 10 m, so the curve can be matched to the pool and the filter you already have.\u003c\/p\u003e\n\u003ch3\u003eTechnical data\u003c\/h3\u003e\n\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\u003cth\u003eBody and pre-filter\u003c\/th\u003e\u003ctd\u003eGlass-fibre reinforced polypropylene\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003cth\u003eShaft, mechanical seal and screws\u003c\/th\u003e\u003ctd\u003eAISI-316 stainless steel\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003cth\u003ePre-filter basket\u003c\/th\u003e\u003ctd\u003ePolyethylene, with a clear polycarbonate lid\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003cth\u003eMotor\u003c\/th\u003e\u003ctd\u003eIE3 asynchronous up to 10 HP, with lifetime lubricated bearings\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003cth\u003eSpeed\u003c\/th\u003e\u003ctd\u003e1,450 rpm from 2.5 to 10 HP; 2,850 rpm on the 2-1250 and the 2-1500\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003cth\u003eProtection and insulation\u003c\/th\u003e\u003ctd\u003eIP-55, class F\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003cth\u003eMaximum water temperature\u003c\/th\u003e\u003ctd\u003e40 °C\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003cth\u003eConnection\u003c\/th\u003e\u003ctd\u003eDN 110 flange on suction and discharge\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003cth\u003eFrequency\u003c\/th\u003e\u003ctd\u003e50 Hz; 60 Hz on request\u003c\/td\u003e\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\n\u003ch3\u003eModels and data by variant\u003c\/h3\u003e\n\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\u003cth\u003eModel\u003c\/th\u003e\u003cth\u003ePower\u003c\/th\u003e\u003cth\u003eFlow at 10 m\u003c\/th\u003e\u003cth\u003eCurrent at 400 V\u003c\/th\u003e\u003cth\u003eSpeed\u003c\/th\u003e\u003cth\u003eWeight\u003c\/th\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003cth\u003eMagnus 4-250\u003c\/th\u003e\u003ctd\u003e2.5 HP (1.8 kW)\u003c\/td\u003e\u003ctd\u003e32 m³ per hour\u003c\/td\u003e\u003ctd\u003e4.9 A\u003c\/td\u003e\u003ctd\u003e1,450 rpm\u003c\/td\u003e\u003ctd\u003e42 kg\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003cth\u003eMagnus 4-300\u003c\/th\u003e\u003ctd\u003e3 HP (2.2 kW)\u003c\/td\u003e\u003ctd\u003e43 m³ per hour\u003c\/td\u003e\u003ctd\u003e5.3 A\u003c\/td\u003e\u003ctd\u003e1,450 rpm\u003c\/td\u003e\u003ctd\u003e42.5 kg\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003cth\u003eMagnus 4-400\u003c\/th\u003e\u003ctd\u003e4 HP (3 kW)\u003c\/td\u003e\u003ctd\u003e56 m³ per hour\u003c\/td\u003e\u003ctd\u003e6.9 A\u003c\/td\u003e\u003ctd\u003e1,450 rpm\u003c\/td\u003e\u003ctd\u003e44.5 kg\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003cth\u003eMagnus 4-550\u003c\/th\u003e\u003ctd\u003e5.5 HP (4 kW)\u003c\/td\u003e\u003ctd\u003e84 m³ per hour\u003c\/td\u003e\u003ctd\u003e8.8 A\u003c\/td\u003e\u003ctd\u003e1,450 rpm\u003c\/td\u003e\u003ctd\u003e53.4 kg\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003cth\u003eMagnus 4-750\u003c\/th\u003e\u003ctd\u003e7.5 HP (5.5 kW)\u003c\/td\u003e\u003ctd\u003e107 m³ per hour\u003c\/td\u003e\u003ctd\u003e12 A\u003c\/td\u003e\u003ctd\u003e1,450 rpm\u003c\/td\u003e\u003ctd\u003e66 kg\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003cth\u003eMagnus 4-1000\u003c\/th\u003e\u003ctd\u003e10 HP (7.5 kW)\u003c\/td\u003e\u003ctd\u003e126 m³ per hour\u003c\/td\u003e\u003ctd\u003e15.8 A\u003c\/td\u003e\u003ctd\u003e1,450 rpm\u003c\/td\u003e\u003ctd\u003e76 kg\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003cth\u003eMagnus 2-1250\u003c\/th\u003e\u003ctd\u003e12.5 HP (9.2 kW)\u003c\/td\u003e\u003ctd\u003e152 m³ per hour\u003c\/td\u003e\u003ctd\u003e18.5 A\u003c\/td\u003e\u003ctd\u003e2,850 rpm\u003c\/td\u003e\u003ctd\u003e84.5 kg\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003cth\u003eMagnus 2-1500\u003c\/th\u003e\u003ctd\u003e15 HP (11 kW)\u003c\/td\u003e\u003ctd\u003e177 m³ per hour\u003c\/td\u003e\u003ctd\u003e20.9 A\u003c\/td\u003e\u003ctd\u003e2,850 rpm\u003c\/td\u003e\u003ctd\u003e85.5 kg\u003c\/td\u003e\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\n\u003ch3\u003eCompatibility and limits\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e110 mm pipework with counter-flanges; the DN 100 PVC flange kit is sold separately.\u003c\/li\u003e\n\u003cli\u003eSalt water with the AISI-316 mechanical seal; sea water with a silicon carbide seal on request, according to Saci.\u003c\/li\u003e\n\u003cli\u003eThree-phase supply: 230 or 400 V up to 5.5 HP, 400 V from 7.5 HP.\u003c\/li\u003e\n\u003cli\u003eFixed speed: it does not regulate flow.
