The Variant C cooling jacket supports continuous submerged operation at depths up to 20 m as part of the Range 66 series.\u003c\/p\u003e\u003cp\u003eFlow capacity reaches 23880 L\/min from the 533 mm ductile iron impeller, driven by a 50 kW motor (P2) at 726 rpm from a 415 V three-phase supply. The unit draws 98 A and achieves 89% efficiency at full load and 91% at 3\/4 load, with DN250 outlet and DN105 inlet connections carrying a PN10 pressure rating.\u003c\/p\u003e\u003cp\u003eHydraulic performance is provided by a 2-channel ductile iron impeller with 105 mm free passage, with the impeller diameter and dual-channel configuration matched to the H lifting height class requirements. The impeller geometry determines the head and flow characteristics for this Range 66 model, with the pump housing constructed from ductile cast iron and CE and EAC markings present on the nameplate.\u003c\/p\u003e\u003cp\u003eDuctile cast iron construction with IP68 enclosure and Class F insulation provides submerged durability, with primary silicon carbide and secondary silicon carbide-carbon shaft seals preventing liquid ingress. Integrated moisture sensors are fitted as standard, and the 15 m H07RN-F AT cable supports Star\/Delta starting.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eRange 66 motor platform with increased external dimensions and enhanced cooling system configuration\u003c\/li\u003e\n\u003cli\u003eEight-pole motor design operating at 726 rpm for reduced hydraulic loading during operation\u003c\/li\u003e\n\u003cli\u003eDual-channel ductile iron impeller providing stable hydraulic performance across the operating range\u003c\/li\u003e\n\u003cli\u003e105 mm free passage through the impeller and volute for solids and unscreened sewage particulates\u003c\/li\u003e\n\u003cli\u003eDuctile cast iron pump housing providing enhanced material strength for demanding wastewater applications\u003c\/li\u003e\n\u003cli\u003eDN250 outlet connection and DN105 inlet connection with PN10 pressure rating\u003c\/li\u003e\n\u003cli\u003eIP68 enclosure protection for continuous submerged operation at depths up to 20 metres\u003c\/li\u003e\n\u003cli\u003eCE and EAC certification markings present on the product nameplate as specified by the manufacturer\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eIMPORTANT:\u003c\/strong\u003e Bulk freight charges apply.
