The Variant C cooling jacket enables continuous submerged operation at depths up to 20 m.\u003c\/p\u003e\u003cp\u003eA 20 kW motor (P2) at 735 rpm from a 415 V three-phase supply draws 40 A with 89% efficiency at full load and 88% at 3\/4 load. Maximum head is 9.3 m, with DN300 outlet and DN145 inlet connections carrying a PN10 pressure rating for this configuration.\u003c\/p\u003e\u003cp\u003eHydraulic performance is provided by a 2-channel ductile iron impeller with 145 mm free passage, with the impeller diameter and dual-channel configuration matched to the E lifting height class requirements. The 388 mm impeller geometry determines the head and flow characteristics for this Range 62 model.\u003c\/p\u003e\u003cp\u003eCast 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 S1BN8-F cable supports Star\/Delta starting.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e8-Pole Motor Design: The 8-pole motor operates at 735 rpm, providing low-speed operation suitable for high-volume transfer applications where reduced hydraulic loading is beneficial.\u003c\/li\u003e\n\u003cli\u003e2-Channel Ductile 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\u003e145 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 \/ DN145 Connection: The outlet connection is sized at DN300 with a PN10 pressure rating, while the inlet connection is DN145, 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.
