This cast iron pump manages untreated wastewater and contaminated media containing solids, ensuring reliable high-pressure wastewater transfer. The unit is intended for permanent service in infrastructure with liquid temperatures from 0°C to +40°C.\u003c\/p\u003e\u003cp\u003eDriven by a 50 kW 4-pole motor at 1470 rpm, the pump achieves a maximum head of 67.1 m and a maximum flow of 6000 L\/min. Operating on a three-phase 415 V supply with 98 Amps, stable motor operation is maintained during high-capacity transfer. A Y\/D starting method provides reliable pumping performance for high-pressure discharge requirements.\u003c\/p\u003e\u003cp\u003eA 1-channel impeller provides the hydraulic force, featuring a 398 mm actual diameter and an 80 mm free passage for handling solids. The DN 125 outlet incorporates DIN flanges and a PN 10 pressure rating to support high-efficiency wastewater transfer. This design is optimized for municipal collection and transfer applications where clogging prevention is a critical operational priority.\u003c\/p\u003e\u003cp\u003eStructural durability is provided by the EN-GJL-250 cast iron casing and double SIC\/SIC-CARBON mechanical shaft seals. Safety is monitored by integrated moisture sensors and leakage detection to ensure motor protection in submerged environments. The unit includes 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 398 mm actual diameter and 80 mm passage for handling solids.\u003c\/li\u003e\n\u003cli\u003eCast iron EN-GJL-250 pump housing and motor casing for structural integrity in utility sumps.\u003c\/li\u003e\n\u003cli\u003eDouble mechanical shaft seal with SIC primary faces and SIC-CARBON secondary seal protection.\u003c\/li\u003e\n\u003cli\u003eIntegrated moisture sensors and thermal switches 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 stations.\u003c\/li\u003e\n\u003cli\u003eFrame size 62 construction for higher discharge pressure applications and raw sewage.\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.
