Product Overview
With flow capacity reaching 50400 L/min and maximum head of 8.4 m, the Grundfos S3.120.600.500.8.66E.C.432.G.N.D.513GPA 8-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.
A 50 kW motor (P2) operating at 726 rpm from a 415 V three-phase supply draws 98 A with 89% efficiency at full load and 91% at 3/4 load. The 432 mm ductile iron impeller delivers the specified performance, with DN600 outlet and DN120 inlet connections carrying a PN10 pressure rating for this configuration.
A 3-channel ductile iron impeller with 120 mm free passage forms the hydraulic core, with the impeller diameter and triple-channel configuration matched to the E 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
- Eight-pole motor design operating at 726 rpm for low-speed high-volume transfer applications
- Triple-channel ductile iron impeller providing stable hydraulic performance across the operating range
- 120 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
- DN600 outlet connection and DN120 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 full hydraulic load, what vertical dynamic head does this submersible pump reach?
Hydraulic elevation force delivered by the S3.120.600.500.8.66E.C.432 reaches a peak dynamic head rating of approximately 8.4 m.
Across large collection networks, what peak flow volume does this pump deliver?
Volumetric displacement through a DN 600 (standard flanged connection) reaches a peak flow rate of approximately 50400 L/Min on the Grundfos S3.120.600.500.8.66E.C.432.
What alloy material and casing construction ensure smooth passage of large wastewater solids?
Evacuating heavy solids without obstruction, the S3-120-600-500-8-66E-C-432 relies on Ductile cast iron housing and wetted components and a high-capacity channel impeller clearing matter up to 120 mm.
Regarding electrical input, what supply voltage and motor power current drive this pump?
Electrical service specifications dictate that the S3 120 600 500 8 66E C 432 operates on 415 V, 50 Hz, three-phase powering a 50 kW motor that pulls 98 A.
Regarding submerged duty cycles, what maximum immersion depth and fluid temperature are permitted?
Submerged collection pit service allows the S3.120.600.500.8.66E.C.432.G.N.D.513GPA to be installed at depths up to approximately 20 m with temperatures up to 40°C.
