Product Overview
With a 533 mm impeller and maximum head of 25.5 m, the Grundfos S2.105.250.500.8.66H.C.533.G.N.D.513GPA 8-pole submersible sewage pump handles wastewater, process water and unscreened raw sewage across Australia where high flow rates and large solids passage are required. The Variant C cooling jacket supports continuous submerged operation at depths up to 20 m as part of the Range 66 series.
Flow capacity reaches 23880 L/min from the 533 mm ductile iron impeller, driven by a 50 kW motor (P2) at 726 rpm from a 415 V three-phase supply. The unit draws 98 A and achieves 89% efficiency at full load and 91% at 3/4 load, with DN250 outlet and DN105 inlet connections carrying a PN10 pressure rating.
Hydraulic performance is provided by a 2-channel ductile iron impeller with 105 mm free passage, with the impeller diameter and dual-channel configuration matched to the H 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
- Range 66 motor platform with increased external dimensions and enhanced cooling system configuration
- Eight-pole motor design operating at 726 rpm for reduced hydraulic loading during operation
- Dual-channel ductile iron impeller providing stable hydraulic performance across the operating range
- 105 mm free passage through the impeller and volute for solids and unscreened sewage particulates
