Product Overview
Addressing long-term continuous municipal transfer demands, this pump is exclusively designed for handling wastewater, process water, unscreened raw sewage, municipal, domestic and industrial applications. The S3.120.300.1000.6.70M.S.428.G.N.D.513GPA model is strictly suitable for submerged physical installation configurations natively utilizing the 96782484 auto coupling interface connection to establish a continuous processing layout.
Constructed from Cast iron EN 1561 EN-GJL-250, the heavy external housing entirely surrounds internal dynamic components. The 3-channel impeller, measuring exactly 429 mm in physical diameter, natively processes suspended solids up to 120 mm in overall size. The internal core motor enclosure is manufactured from Cast iron EN 1561 EN-GJL-250. The component weighs 1280 kg and operates continuously in Newtonian liquids up to 40°C.
The 100 kW motor system functions on a three-phase 415v supply, operating with a rated continuous electrical current of 183 Amps. The heavy-duty unit achieves a maximum head of 27.6 meters and a maximum flow volume of 40500 L/Min through a physical DN 300 mm discharge outlet. The continuous operating power input P1 is specified exactly at 109 kW, operating alongside a specific starting current parameter evaluated at 1200 Amps.
Internal hardware safety is governed by Class F internal motor insulation combined with an IP68 physical liquid enclosure rating. The structure technically supports rigid vertical installation depths extending up to 20 meters. Primary SIC mechanical seals and secondary SIC-CARBON shaft seals strictly provide internal liquid containment. The internal electrical architecture incorporates a 6-pole motor structure combined with a Y/D start mechanism.
Features
