Product Overview
With flow capacity reaching 7980 L/min and maximum head of 48.6 m, the Grundfos S1.100.125.400.4.62M.C.345.G.N.D.513GPA submersible sewage pump handles wastewater, process water and unscreened raw sewage in municipal and industrial applications. The Variant C cooling jacket enables continuous submerged operation at depths up to 20 m where medium head performance is required.
A 43 kW motor (P2) at 1464 rpm from a 415 V three-phase supply draws 86 A with 89% efficiency at both full and 3/4 load. The 345 mm impeller delivers the specified performance, with DN125 outlet and DN100 inlet connections carrying a PN10 pressure rating for this configuration.
Hydraulic performance is provided by a 1-channel cast iron impeller with 100 mm free passage, with the impeller diameter and channel configuration matched to the M lifting height class requirements. The single-channel impeller geometry determines the head and flow characteristics for this Range 62 model.
Cast 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 H07RN-F AT 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.
- 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.
- DN125 / DN100 Connection: The outlet connection is sized at DN125 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.
