\u003c\/p\u003e\n\n  \u003ch4\u003eWhy choose the BQBE seal?\u003c\/h4\u003e\n  \u003cp\u003e\n    BQBE combines a \u003cstrong\u003esilicon-carbide primary face\u003c\/strong\u003e with a \u003cstrong\u003ecarbon-impregnated counterface\u003c\/strong\u003e.  \n    This pairing offers very good corrosion resistance and smooth, low-friction running in clean heating and cooling water, while the silicon-carbide face provides improved wear resistance compared with softer materials.\n    It is a practical and widely used seal choice for normal HVAC circulation duties.\n  \u003c\/p\u003e\n\n  \u003cp\u003e\n    \u003cstrong\u003eAir-conditioning note:\u003c\/strong\u003e BQBE is suitable for \u003cstrong\u003echilled-water systems operating above 0 °C\u003c\/strong\u003e.  \n    It is \u003cstrong\u003enot suitable\u003c\/strong\u003e for sub-zero brine\/glycol circuits, ice-storage systems, or refrigerants where liquid temperature may fall below 0 °C.\n  \u003c\/p\u003e\n\n  \u003ch4\u003eCan one head be used as standby?\u003c\/h4\u003e\n  \u003cp\u003e\n    Yes – the TPD twin configuration allows duty\/standby or parallel operation, \u003cstrong\u003ebut this requires an external control system\u003c\/strong\u003e.\n    Automatic changeover and alternation are not managed by the pump itself; they must be provided by a \u003cstrong\u003eseparate control panel, inverter drive system, or BMS controller\u003c\/strong\u003e configured for twin-pump operation.\n  \u003c\/p\u003e\n\n  \u003ch4\u003eIs this suitable to replace other DN80 circulators?\u003c\/h4\u003e\n  \u003cp\u003e\n    This model uses \u003cstrong\u003eDN80 PN10 DIN flanges\u003c\/strong\u003e with a \u003cstrong\u003eport-to-port length of 360 mm\u003c\/strong\u003e.\n    Where dimensions match, it can replace other DN80 in-line circulators from manufacturers such as Wilo, Lowara and KSB, subject to hydraulic duty and system requirements.\n
