Quote part number 93320263 to have it arrive pre-configured and ready for the plant room.\u003c\/p\u003e\u003cp\u003eFlow capacity reaches 4718 L\/min. Up to 47 metres of head is available to maintain pressure as demand changes. 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 200 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 40.9 A. Motors are protected to IP54, 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 industrial process supply, mixed-use commercial buildings and schools and universities.
