Everything is ordered under the single part number 99752252.\u003c\/p\u003e\u003cp\u003eThis set provides up to 504 L\/min of flow capacity. Variable-speed operation can develop up to 13 metres of head where required. 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 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\u003eTypical duty sits with mixed-use commercial buildings, hospitals and schools and universities.
