Product Overview
Continuous fluid extraction for agricultural and municipal water networks requires pumps with reliable performance and corrosion-resistant construction. The Lowara ZN660/21-3 features a 6-inch wet end with 6-inch motor, delivering 1300 L/Min for demanding water transfer applications. The multi-stage hydraulic assembly ensures stable output across varying demand conditions.
Protection against corrosion comes from AISI 316 stainless steel across every wetted component, ensuring long-term durability in aggressive groundwater environments. The suction strainer limits sand ingress to 100 grams per cubic metre, protecting internal clearances from premature wear. The impeller incorporates a removable wear ring for maintenance convenience, while the integrated non-return valve prevents reverse flow. The microcast stainless steel housing provides structural integrity.
Power is provided by a 37 kW three-phase motor at 415V drawing 81.8 Amps. Maximum head reaches 225.7 metres at shut-off with flow capacity of 1300 L/Min through the 80 mm discharge outlet. Hydraulic performance conforms to EN ISO 9906 Grade 3B tolerances for reliable operation.
Immersion depths to 350 metres are supported with Class F insulation and IP68 rating. The Duplex stainless steel shaft and AISI 316L tie rods provide mechanical durability. NEMA motor compatibility simplifies assembly, and safety hook attachment points on the discharge head facilitate installation.
