The complete system ships factory assembled and tested under part number 93320239.\u003c\/p\u003e\u003cp\u003eThe system supports flow rates up to 2113 L\/min. It can develop up to 98 metres of head for dependable pressure boosting. 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 150 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 58.7 A, with IP54 motor protection and a 16 bar maximum system pressure. Liquid-temperature suitability is 5°C to 60°C. Inlet pressure is rated to 16 bar.\u003c\/p\u003e\u003cp\u003eExpect it on industrial process supply and hotel plant rooms sites, plus schools and universities duties.
