The complete system ships factory assembled and tested under part number 99657296.\u003c\/p\u003e\u003cp\u003eIt handles flows up to 1060 L\/min across the system. The pumps can develop up to 123 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\u003eFactory assembled on a common base, the set combines stainless steel pipework, two 80 mm manifold connections, isolation and non-return valves, pressure sensors and a gauge, plus a 24L diaphragm tank. It connects to a 3 x 380-415 V supply at 50 \/ 60 Hz with a rated current of 30 A. Motors are protected to IP54, while maximum system pressure is 16 bar. Liquid-temperature suitability is 5°C to 60°C. Inlet pressure is rated to 16 bar.\u003c\/p\u003e\u003cp\u003eTypical duty sits with industrial process supply, hospitals and schools and universities.
