The Variant C cooling jacket supports continuous submerged operation at depths up to 20 m.\u003c\/p\u003e\u003cp\u003eA 15 kW motor (P2) at 485 rpm from a 415 V three-phase supply draws 36 A with 84% efficiency at full load and 85% at 3\/4 load. The 449 mm impeller delivers the specified performance, with DN300 outlet and DN120 inlet connections carrying a PN10 pressure rating.\u003c\/p\u003e\u003cp\u003eHydraulic performance is achieved through a 3-channel ductile iron impeller with 120 mm free passage, with the impeller diameter and triple-channel configuration matched to the F lifting height class requirements. The impeller geometry determines the head and flow characteristics for this Range 62 model.\u003c\/p\u003e\u003cp\u003eIP68 enclosure and Class F insulation are provided by the cast iron housing, with primary silicon carbide and secondary silicon carbide-carbon shaft seals protecting the motor compartment.
