The complete system ships factory assembled and tested under part number 99752121.\u003c\/p\u003e\u003cp\u003eIt handles flows up to 166 L\/min across the system. The pumps can develop up to 46 metres of head when pressure demand increases. Because every pump carries its own frequency converter and the Multi-Master software elects the controlling pump itself, losing a control unit or pressure sensor means seamless handover rather than a shutdown.\u003c\/p\u003e\u003cp\u003eFactory assembled on a common base, the set combines stainless steel pipework, two 50 mm manifold connections, isolation and non-return valves, pressure sensors and a gauge, plus a 24L diaphragm tank. It connects to a 1 x 200-240 V supply at 50 \/ 60 Hz with a rated current of 6.68 A. Motors are protected to IP55, while maximum system pressure is 10 bar. Liquid-temperature suitability is 5°C to 60°C. Inlet pressure is rated to 10 bar.\u003c\/p\u003e\u003cp\u003eApplications include schools and universities, mixed-use commercial buildings and high-rise apartments.
