Part number 99614230 provides the complete tested package in a single order line.\u003c\/p\u003e\u003cp\u003eThe system supports flow rates up to 231 L\/min. It can develop up to 36 metres of head for dependable pressure boosting. 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\u003eThe three-pump package arrives as one base-mounted assembly with stainless steel manifolds, two 50 mm manifold connections, valves, sensors and a pressure gauge, plus a 24L diaphragm tank. Electrical supply is 1 x 200-240 V at 50 \/ 60 Hz with a rated current of 7.17 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 industrial process supply sites, plus hotel plant rooms duties.
