However, BUBE is less tolerant of dirty liquids, solids, crystallisation and additive deposits, because particles can become embedded in the carbon face and increase wear.\n\u003c\/p\u003e\n\n\u003ch4\u003eWhat temperature range can this pump operate at?\u003c\/h4\u003e\n\n\u003cp\u003e\nFor this product number, Grundfos lists a liquid temperature range of \u003cstrong\u003e0°C to +140°C\u003c\/strong\u003e.

Any external speed control or system control would need to be considered separately and must be compatible with the motor.\n\u003c\/p\u003e\n\n\u003ch4\u003eWill this replace my existing DN40 TP pump?\u003c\/h4\u003e\n\n\u003cp\u003e\nThis pump has \u003cstrong\u003eDN40 DIN flanged connections\u003c\/strong\u003e, \u003cstrong\u003ePN6\/10 flange rating\u003c\/strong\u003e, a \u003cstrong\u003e250 mm port-to-port length\u003c\/strong\u003e and a \u003cstrong\u003esingle-phase 220–230\/240V 50Hz motor\u003c\/strong\u003e. It may be a suitable replacement for matching Grundfos TP 40-120\/2 installations, but the product number, flange standard, port-to-port length, voltage, shaft seal and duty point should be checked before ordering.\n\u003c\/p\u003e\n\n\u003ch4\u003eWhat electrical supply does it need?\u003c\/h4\u003e\n\n\u003cp\u003e\nThis pump is a \u003cstrong\u003esingle-phase 50Hz unit\u003c\/strong\u003e with a rated voltage of \u003cstrong\u003e1 × 220–230\/240V\u003c\/strong\u003e.
