Product Overview
Flow capacity of 26400 L/min and maximum head of 15.9 m position the Grundfos S2.140.300.350.8.66M.C.438.G.N.D.513GPA 8-pole submersible sewage pump for wastewater, process water and unscreened raw sewage applications 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.
A 35 kW motor (P2) operating at 732 rpm from a 415 V three-phase supply draws 73 A with 88% efficiency at both full and 3/4 load. The 438 mm ductile iron impeller delivers the specified performance, with DN300 outlet and DN140 inlet connections carrying a PN10 pressure rating for this configuration.
Hydraulic performance is provided by a 2-channel ductile iron impeller with 140 mm free passage, with the impeller diameter and dual-channel configuration matched to the M 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
- Eight-pole motor design operating at 732 rpm for low-speed high-volume transfer applications
