Everything is ordered under the single part number 99752280.\u003c\/p\u003e\u003cp\u003eFlow capacity reaches 509 L\/min. Up to 28 metres of head is available to maintain pressure as demand changes. 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 two-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 3 x 380-415 V at 50 \/ 60 Hz with a rated current of 4.74 A. The motors have IP55 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\u003eTypical duty sits with high-rise apartments, hospitals and industrial process supply.
