This cast iron unit provides consistent transfer performance in heavy-duty utility networks. It is engineered for service in infrastructure environments with liquid temperatures from 0°C to +40°C.\u003c\/p\u003e\u003cp\u003eThe pump achieves a maximum head of 46.8 m and a maximum flow of 6600 L\/min, powered by a 30 kW 4-pole motor. Operating on a three-phase 415 V supply with a 64 Amp rated current, stable motor operation is maintained during high-capacity transfer cycles. A Y\/D starting method is utilized to maintain pumping performance within demanding wastewater infrastructure.\u003c\/p\u003e\u003cp\u003ePumping performance is achieved using a 1-channel cast iron impeller with a 338 mm actual diameter and an 80 mm free passage for managing untreated wastewater. The discharge configuration features a DN 125 outlet with a PN 10 pressure rating to support consistent discharge pressure. This design focuses on high-efficiency transfer while helping to reduce the risk of clogging in discharge piping.\u003c\/p\u003e\u003cp\u003eStructural integrity is provided by the EN-GJL-250 cast iron pump housing and motor casing, which protect the internal components in submerged conditions. The unit features a double mechanical SIC shaft seal and SIC-CARBON secondary seal, alongside moisture sensors for motor protection. It 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 338 mm 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 stations.\u003c\/li\u003e\n\u003cli\u003eDouble mechanical shaft seal with SIC primary faces and SIC-CARBON secondary barrier 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 permanent submerged installation in wet wells up to 20 metres deep.\u003c\/li\u003e\n\u003cli\u003eSupplied with a 15-metre H07RN-F power cable for reliable electrical connection in municipal grids.\u003c\/li\u003e\n\u003cli\u003eFrame size 62 construction for municipal sewage and wastewater containing solids.\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.
