Quote part number 99614330 to have it arrive pre-configured and ready for the plant room.\u003c\/p\u003e\u003cp\u003eIt handles flows up to 455 L\/min across the system. The pumps can develop up to 38 metres of head when pressure demand increases. There is no separate central controller to purchase: Multi-Master control resides within the pumps, either unit can assume the controlling role, and a fault is handed over cleanly without interrupting supply.\u003c\/p\u003e\u003cp\u003eFor installation, the booster is supplied pre-assembled with stainless steel manifolds, two 50 mm manifold connections, isolation valves, non-return valves, pressure sensors and a gauge, plus a 24L diaphragm tank. It is designed for 1 x 200-240 V power at 50 \/ 60 Hz with a rated current of 13.5 A, with IP54 motor protection and a 10 bar maximum system pressure. Liquid-temperature suitability is 5°C to 60°C. Inlet pressure is rated to 10 bar.\u003c\/p\u003e\u003cp\u003eTypical duty sits with hotel plant rooms, schools and universities and aged-care complexes.
