Product Overview
Flow capacity of 20700 L/min and maximum head of 17.6 m position the Grundfos S2.100.300.400.4.62E.C.281.G.N.D.513GPA submersible sewage pump for wastewater, process water and unscreened raw sewage applications where very high flow rates at low heads are required. The Variant C cooling jacket supports continuous submerged operation at depths up to 20 m.
Power 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.
A 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.
IP68 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.
FEATURES
- Range 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.
- 2-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.
- 100 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.
- DN300 / 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.
- Variant 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.
- IP68 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.
- Silicon 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.
- Integrated 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.
