Flow capacity of 24000 L/min and maximum head of 38.7 m position the Grundfos S2.110.250.650.4.66L.C.327.G.N.D.513GPA submersible sewage pump for wastewater, process water and unscreened raw sewage applications across Australia where very high flow rates at medium heads are required. The Variant C cooling jacket supports continuous submerged operation at depths up to 20 m as part of the Range 66 series.
A 68 kW motor (P2) operating at 1476 rpm from a 415 V three-phase supply draws 129 A with 93% efficiency at both full and 3/4 load. The 327 mm ductile iron impeller delivers the specified performance, with DN250 outlet and DN110 inlet connections carrying a PN10 pressure rating for this configuration.
Hydraulic performance is provided by a 2-channel ductile iron impeller with 110 mm free passage, with the impeller diameter and dual-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 CE and EAC markings present on the nameplate.
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 66 motor platform with increased external dimensions and enhanced cooling system configuration
- Dual-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
