Product Overview
With flow capacity reaching 39000 L/min and maximum head of 12.1 m, the Grundfos S3.110.500.350.10.66L.C.474.G.N.D.513GPA 10-pole submersible sewage pump handles wastewater, process water and unscreened raw sewage across Australia where extremely high flow rates at low heads are required. The Variant C cooling jacket enables continuous submerged operation at depths up to 20 m as part of the Range 66 series.
Power comes from a 35 kW motor (P2) operating at 585 rpm from a 415 V three-phase supply, drawing 77 A with 88% efficiency at both full and 3/4 load. The 466 mm ductile iron impeller delivers the specified performance, with DN500 outlet and DN110 inlet connections carrying a PN10 pressure rating for this configuration.
A 3-channel ductile iron impeller with 110 mm free passage forms the hydraulic core, with the impeller diameter and triple-channel configuration matched to the L lifting height class requirements. The impeller geometry determines the head and flow characteristics for this Range 66 model, with the pump housing constructed from ductile cast iron and CE and EAC markings present on the nameplate.
Ductile 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
- Ten-pole motor design operating at 585 rpm for very low-speed high-volume transfer applications
- Triple-channel ductile iron impeller providing stable hydraulic performance across the operating range
- 110 mm free passage through the impeller and volute for solids and unscreened sewage particulates
- Ductile cast iron pump housing providing enhanced material strength for demanding wastewater applications
- DN500 outlet connection and DN110 inlet connection with PN10 pressure rating
- IP68 enclosure protection for continuous submerged operation at depths up to 20 metres
- Variant C integrated cooling jacket surrounding the motor stator for heat dissipation during operation
- CE and EAC certification markings present on the product nameplate as specified by the manufacturer

Under peak municipal pumping, what maximum flow rate in liters per minute is achieved?
Facility collection pipework interfaces with the S3.110.500.350.10.66L.C.474 via a DN 500 (standard flanged connection), delivering a maximum flow volume of approximately 39000 L/Min.
How does the casing metallurgy and alloy construction prevent ragging and clogging in heavy sewage applications?
Non-clogging wastewater displacement on the Grundfos S3.110.500.350.10.66L.C.474 depends on Ductile cast iron housing and wetted components and a high-clearance channel impeller accommodating solids up to 110 mm.
What electrical motor power specifications and line current draw energize this wastewater pump?
Operating in municipal electrical networks, the S3-110-500-350-10-66L-C-474 features an industrial motor rated at 35 kW connecting to 415 V, 50 Hz, three-phase at 77 A.
Under demanding effluent service, what immersion depth limit and thermal endurance are provided?
Submerged pit engineering allows the S3 110 500 350 10 66L C 474 to operate at installation depths up to approximately 20 m handling wastewater up to 40°C.
Across vertical municipal mains, what fluid lift head is produced by this pump?
Overcoming hydraulic elevation resistance, the S3.110.500.350.10.66L.C.474.G.N.D.513GPA reaches a peak dynamic head rating of approximately 12.1 m.
