The complete system ships factory assembled and tested under part number 93328665.\u003c\/p\u003e\u003cp\u003eThis set provides up to 3474 L\/min of flow capacity. Variable-speed operation can develop up to 60 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\u003eThe two-pump package arrives as one base-mounted assembly with stainless steel manifolds, two 150 mm manifold connections, valves, sensors and a pressure gauge, plus a 24L diaphragm tank. Electrical supply is 3 x 380-415 V at 50 \/ 60 Hz with a rated current of 51.6 A. The motors have IP54 protection and the system is rated to 10 bar maximum pressure. Liquid-temperature suitability is 5°C to 60°C. Inlet pressure is rated to 10 bar.\u003c\/p\u003e\u003cp\u003eExpect it on hospitals and mixed-use commercial buildings sites, plus aged-care complexes duties.
