Specify part number 99752206 and the whole set lands tested, assembled and ready for pipework.\u003c\/p\u003e\u003cp\u003eIt handles flows up to 304 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 9.02 A, with IP55 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\u003eExpect it on mixed-use commercial buildings and aged-care complexes sites, plus industrial process supply duties.
