Product Overview
Delivering up to 47 m head from a 30 kW motor, the Grundfos S1.80.125.300.4.62H.C.338.G.N.D.513GPA submersible sewage pump handles wastewater, process water and unscreened raw sewage in municipal, domestic and industrial settings. The Variant C cooling jacket supports continuous submerged operation at depths up to 20 m, with installation suited to permanent wet well applications where higher discharge pressures are needed.
Maximum flow reaches 6600 L/min from the 338 mm impeller, with the 4-pole motor operating at 1482 rpm on a 415 V three-phase supply. The unit draws 64 A and achieves 89% efficiency at full load, with 84% efficiency at half load. DN125 outlet and DN80 inlet connections carry a PN10 pressure rating for this configuration.
A 1-channel cast iron impeller with 80 mm free passage forms the hydraulic core, with the impeller diameter and channel configuration determining the head and flow characteristics for the H lifting height class. The impeller geometry is matched to the hydraulic requirements of this Range 62 model.
IP68 enclosure protection and Class F insulation are provided by the cast iron pump housing, with the sealing arrangement using a primary silicon carbide shaft seal and a secondary silicon carbide-carbon combination. Integrated moisture sensors are fitted as standard, and the 15 m H07RN-F AT power cable supports 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.
- 1-Channel Cast Iron Impeller: The single-channel impeller design provides stable hydraulic performance across the operating range while maintaining efficient solids handling capability for municipal wastewater applications.
- 80 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.
- DN125 / DN80 Connection: The outlet connection is sized at DN125 with a PN10 pressure rating, while the inlet connection is DN80, 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.
