This cast iron pump is built for permanent submerged service in collection networks where raw sewage and untreated wastewater contain solids. It ensures consistent hydraulic transfer in utility environments with liquid temperatures from 0°C to +40°C.\u003c\/p\u003e\u003cp\u003eA 41 kW 4-pole motor running at 1464 rpm provides the power to achieve a maximum flow of 6600 L\/min and 57.5 m head. Drawing 82 Amps from a 415 V supply, stable motor operation is maintained during heavy-volume transfer cycles. The system supports consistent discharge pressure for high-lift requirements in wastewater infrastructure.\u003c\/p\u003e\u003cp\u003eThe hydraulic system uses a 1-channel cast iron impeller with a 374 mm actual diameter and an 80 mm free passage for managing untreated wastewater. Featuring a DN 125 outlet with DIN flanges, the design supports efficient wastewater transfer through high-head discharge systems. This setup helps prevent clogging while maintaining the hydraulic efficiency required for municipal grid systems.\u003c\/p\u003e\u003cp\u003eStructural integrity is provided by an EN-GJL-250 cast iron motor casing and pump housing with a double mechanical shaft seal arrangement. Protection monitoring is managed by integrated moisture sensors and thermal switches to ensure motor safety in submerged conditions. The unit is supplied with a 15-metre H07RN-F power cable and is compatible with the Grundfos DN125 auto-coupling system (96782145).\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e1-Channel cast iron impeller with a 374 mm actual diameter and 80 mm passage for handling solids.\u003c\/li\u003e\n\u003cli\u003eEN-GJL-250 cast iron pump housing and motor casing for structural durability in permanent service.\u003c\/li\u003e\n\u003cli\u003eDouble mechanical shaft seal with SIC primary seal and SIC-CARBON secondary barrier protection.\u003c\/li\u003e\n\u003cli\u003eIntegrated moisture switch and thermal sensors for proactive motor protection and monitoring.\u003c\/li\u003e\n\u003cli\u003eIP68 enclosure suitable for installation depths up to 20 metres with a PN 10 rated discharge.\u003c\/li\u003e\n\u003cli\u003eSupplied with a 15-metre H07RN-F power cable for reliable electrical connection in transfer stations.\u003c\/li\u003e\n\u003cli\u003eSuitable for higher discharge pressure applications in municipal and industrial wastewater networks.\u003c\/li\u003e\n\u003cli\u003eCompatible with the Grundfos DN125 auto-coupling system (96782145) for simplified maintenance access.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eIMPORTANT:\u003c\/strong\u003e Bulk freight charges apply.
