The Variant C cooling jacket supports continuous submerged operation at depths up to 20 m.\u003c\/p\u003e\u003cp\u003ePower is supplied by a 43 kW motor (P2) operating at 1464 rpm from a 415 V three-phase supply, drawing 86 A with 89% efficiency at both full and 3\/4 load. The 281 mm impeller delivers the specified performance, with DN300 outlet and DN100 inlet connections carrying a PN10 pressure rating.\u003c\/p\u003e\u003cp\u003eA 2-channel cast iron impeller with 100 mm free passage forms the hydraulic section, with the impeller diameter and dual-channel configuration matched to the E 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. Integrated moisture sensors are fitted as standard, with 15 m H07RN-F AT cable and Star\/Delta starting.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eRange 62 Motor Design: The motor frame incorporates standardized external and internal dimensions, cooling system configuration, shaft seal arrangement and bearing specification common to all pumps in the Range 62 series.\u003c\/li\u003e\n\u003cli\u003e2-Channel Cast Iron Impeller: The dual-channel impeller design provides stable hydraulic performance across the operating range while maintaining efficient solids handling capability for municipal wastewater applications.\u003c\/li\u003e\n\u003cli\u003e100 mm Free Passage: The internal clearance through the impeller and volute allows solids and unscreened sewage particulates to pass without blocking the hydraulic flow path during operation.\u003c\/li\u003e\n\u003cli\u003eDN300 \/ DN100 Connection: The outlet connection is sized at DN300 with a PN10 pressure rating, while the inlet connection is DN100, matching the hydraulic design requirements of this configuration.\u003c\/li\u003e\n\u003cli\u003eVariant C Cooling Jacket: The integrated cooling jacket surrounds the motor stator to dissipate heat during continuous submerged operation, maintaining stable motor temperatures in wet well installations.\u003c\/li\u003e\n\u003cli\u003eIP68 Enclosure Protection: The motor housing is fully sealed against permanent submersion, with the IP68 rating confirming suitability for continuous operation at depths up to 20 m.\u003c\/li\u003e\n\u003cli\u003eSilicon Carbide Shaft Seals: The primary shaft seal uses silicon carbide faces while the secondary seal employs a silicon carbide-carbon combination, providing two-stage protection against liquid ingress into the motor compartment.\u003c\/li\u003e\n\u003cli\u003eIntegrated Moisture Sensors: Sensors are fitted within the motor housing to detect the presence of moisture, providing early indication of potential seal degradation or liquid ingress during service.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eIMPORTANT:\u003c\/strong\u003e Bulk freight charges apply.
