Specify part number 99614351 and the whole set lands tested, assembled and ready for pipework.\u003c\/p\u003e\u003cp\u003eThis set provides up to 668 L\/min of flow capacity. Variable-speed operation can develop up to 57 metres of head where required. 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\u003eFor installation, the booster is supplied pre-assembled with stainless steel manifolds, two 80 mm manifold connections, isolation valves, non-return valves, pressure sensors and a gauge, plus a 24L diaphragm tank. It is designed for 3 x 380-415 V power at 50 \/ 60 Hz with a rated current of 9.3 A, with IP54 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\u003eIts home ground covers aged-care complexes, industrial process supply and hospitals.
