Product Overview
Large-scale irrigation systems and aquatic facility water transfer require pumps that deliver substantial flow with reliable performance. The Lowara 4ZN660/3-3 handles 1300 L/Min through its 6-inch wet end with 4-inch motor connection, making it suitable for farm irrigation networks and water feature applications. The multi-stage hydraulic assembly provides stable output across varying duty cycles.
AISI 316 stainless steel construction throughout the wet end offers excellent resistance to corrosion and abrasive wear. The impeller incorporates a removable wear ring for simplified maintenance, while the integrated non-return valve prevents water column reversal. The suction strainer limits sand ingress to 100 grams per cubic metre, protecting internal clearances. The microcast stainless steel housing provides structural integrity for long-term submersion.
Operating on a 415V three-phase supply, the 5.5 kW motor draws 13.2 Amps and achieves 31.9 metres of shut-off head. Flow capacity is 1300 L/Min through the 80 mm discharge outlet. Performance testing to EN ISO 9906 Grade 3B ensures reliable operation across the full duty range.
Submersion depths up to 300 metres are supported with Class F insulation and IP68 protection. The Duplex stainless steel shaft provides mechanical strength for continuous operation, while AISI 316L tie rods offer additional structural support. NEMA motor compatibility simplifies assembly, and safety hook holes on the discharge head facilitate installation.
