Specify part number 99752235 and the whole set lands tested, assembled and ready for pipework.\u003c\/p\u003e\u003cp\u003eIt handles flows up to 307 L\/min across the system. The pumps can develop up to 78 metres of head when pressure demand increases. 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 50 mm manifold connections, isolation valves, non-return valves, pressure sensors and a gauge, plus a 24L diaphragm tank. It is designed for 1 x 200-240 V power at 50 \/ 60 Hz with a rated current of 17.5 A, with IP55 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\u003eExpect it on hospitals and mixed-use commercial buildings sites, plus hotel plant rooms duties.
