Product Overview
Municipal water supply and pressure boosting in high-rise buildings rely on the Lowara Z875-03-3S, featuring an AISI 316 stainless steel motor. Agricultural irrigation and industrial water distribution also benefit from its performance. The pump supports vertical and horizontal mounting configurations.
An 18.5 kW motor drawing 38.5 Amps at 415V three-phase develops 79.4 m of head and a maximum flow of 1833.3 L/Min. The 125 mm discharge port includes an integrated non-return valve. Hydraulic performance is presented according to ISO 9906:2012 Grade 3B standards.
Constructed from AISI 304 stainless steel, the casing encloses a semi-axial flow impeller trimmed to 143 mm. The assembly weighs 119.4 kg and processes sand up to 100 g/m³ at 25°C. The AISI 316 motor provides corrosion-resistant construction for challenging water conditions.
Class F insulation and IP68 protection allow immersion to 350 m depth. The L6WN185 motor incorporates water-lubricated thrust bearings. NEMA flange mounting and dual cable covers maintain the 198 mm diameter for 8-inch well compatibility.
