Product Overview
Aquatic facility water transfer and large-scale irrigation systems need pumps that combine high flow capacity with corrosion resistance. The Lowara ZN660/4-3 delivers 1300 L/Min from its 6-inch wet end with 6-inch motor, providing reliable water movement for water features, fountains, and extensive farm irrigation networks. The multi-stage hydraulic assembly provides stable performance across varying duty cycles.
AISI 316 stainless steel throughout the wet end offers excellent resistance to the corrosive effects of groundwater and suspended abrasives. The impeller incorporates a removable wear ring for maintenance convenience, while the integrated non-return valve prevents reverse flow. The suction strainer limits sand ingress to 100 grams per cubic metre, protecting internal clearances. The microcast stainless steel housing provides structural integrity.
Operating on a 415V three-phase supply, the 7.5 kW motor draws 17 Amps and achieves 42.8 metres of shut-off head. Flow capacity is 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 holes facilitate installation.
