Product Overview
Extremely corrosive water extraction from deep wells is the primary application for the Lowara ZN875-03/3A-3R, which features an AISI 316 stainless steel pump with a Duplex stainless steel motor. Municipal water supply and pressure boosting in high-rise buildings are also served. The Duplex motor provides corrosion-resistant construction for the most aggressive environments.
An 11 kW motor drawing 24.2 Amps at 415V three-phase delivers 60.2 m of head and a maximum flow of 1700 L/Min. The 125 mm discharge outlet includes an integrated non-return valve. Performance is presented according to ISO 9906:2012 Grade 3B tolerances.
The AISI 316 stainless steel pump casing contains a semi-axial flow impeller trimmed to 134 mm. The assembly weighs 99.4 kg and handles sand up to 100 g/m³ at 25°C. The Duplex stainless steel motor offers corrosion-resistant construction for extreme water conditions.
Class F insulation and IP68 enclosure permit immersion to 350 m depth. The L6WR110 motor incorporates water-lubricated thrust bearings. NEMA flange mounting and dual cable covers maintain the 198 mm diameter for standard well compatibility.
