Product Overview
High-head extraction for municipal water supply and agricultural irrigation requires pumps capable of delivering substantial pressure with reliable performance. The Lowara ZN646/20-3 delivers 205.4 metres of shut-off head from its 6-inch wet end, with a 26 kW motor configuration that provides ample power for demanding applications. The multi-stage hydraulic assembly ensures efficient energy transfer across the operating range.
Corrosion resistance is achieved through AISI 316 stainless steel construction across every wetted surface, protecting against aggressive groundwater and abrasive wear. The impeller and diffuser arrangement incorporates a removable wear ring for simplified maintenance, while the integrated non-return valve prevents backflow during shutdown. The suction strainer limits suspended sand ingress to 100 grams per cubic metre, preserving internal clearances.
Driven by a 26 kW three-phase motor at 415V, the pump draws 56.5 Amps and achieves 205.4 metres of shut-off head. Flow capacity reaches 1000 L/Min through the 80 mm discharge port. Hydraulic performance complies with EN ISO 9906 Grade 3B tolerances for consistent output.
Class F insulation with IP68 rating supports immersion depths to 350 metres. The Duplex stainless steel shaft provides mechanical strength, while AISI 316L tie rods offer structural integrity. Safety hook holes facilitate installation, and NEMA motor compatibility simplifies assembly.
