Its single-stage volute with equal ports mounts directly in the run, and the rotating assembly lifts out from the top for maintenance.\u003c\/p\u003e\u003cp\u003eThe pump housing is cast iron (EN-GJL-250). The rotating assembly uses a corrosion-resistant composite impeller, 74 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 6\/10 DIN flanges (EN 1092-2) with DN 50 ports and a port-to-port length of 280 mm. Net weight is 29.4 kg.\u003c\/p\u003e\u003cp\u003eSpeed varies from 480 to 4000 rpm on a 2.2 kW, 3 x 380-500 V supply (4.35-3.55 A). Maximum flow is 1986 L\/Min (33.10 m³\/h) and maximum head is 24 m, with a rated flow of 1986 L\/Min at 19.6 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in treated and untreated water\u003c\/li\u003e\n\u003cli\u003eTop-pull-out power head lets the motor and impeller be withdrawn without breaking the pipe flanges\u003c\/li\u003e\n\u003cli\u003eBuilt-in frequency converter and PI controller give continuously variable speed without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 6\/10 DIN flanges (EN 1092-2) accept standard 50 mm pipe\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eIMPORTANT:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eBulk freight charges apply.
