It suits chilled water, heating water and general building circulation, and the top-pull-out head lets the motor and impeller be withdrawn without breaking the flanges.\u003c\/p\u003e\u003cp\u003eThe pump housing is cast iron (EN-GJL-250). The rotating assembly uses a corrosion-resistant composite impeller, 121 mm in diameter, suited to treated and untreated water. The shaft seal is a BQQE mechanical seal per EN 12756. Pipe connection is via PN 16 DIN flanges (EN 1092-2) with DN 32 ports and a port-to-port length of 260 mm. Net weight is 34.9 kg.\u003c\/p\u003e\u003cp\u003eSpeed varies from 360 to 4000 rpm on a 1.1 kW, 3 x 380-500 V supply (2.2-1.9 A). Maximum flow is 1074 L\/Min (17.90 m³\/h) and maximum head is 25 m, with a rated flow of 1074 L\/Min at 14.9 m of head.\u003c\/p\u003e\u003cp\u003eDriven by a fan-cooled permanent-magnet synchronous motor classified IE5 per IEC 60034-30-2, the pump carries a built-in frequency converter and PI controller for continuously variable speed. Enclosure class is IP55 with class F insulation. Liquid temperature range is -25 to 120 °C.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eComposite impeller resists corrosion in treated and untreated water\u003c\/li\u003e\n\u003cli\u003eTop-pull-out power head lets the motor and impeller be withdrawn without breaking the pipe flanges\u003c\/li\u003e\n\u003cli\u003eBuilt-in frequency converter and PI controller give continuously variable speed without external drives\u003c\/li\u003e\n\u003cli\u003eIE5 permanent-magnet motor carries no slip losses typical of induction motors\u003c\/li\u003e\n\u003cli\u003eClass F insulation under an IP55 enclosure keeps the windings sealed against dust and moisture\u003c\/li\u003e\n\u003cli\u003ePN 16 DIN flanges (EN 1092-2) accept standard 32 mm pipe\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eIMPORTANT:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eBulk freight charges apply.
