Product Overview
High-head groundwater supply for municipal networks and fountain waterworks requires pumps that deliver substantial pressure with reliable performance. The Lowara ZN646/7-3 meets these requirements with its 6-inch wet end and 6-inch motor configuration, delivering 1000 L/Min while maintaining stable operation across varying demand cycles.
Corrosion resistance is built into the design through AISI 316 stainless steel construction, extending service life in aggressive groundwater conditions. The hydraulic stages feature a removable wear ring for maintenance convenience, while the integrated non-return valve prevents water column reversal. The suction strainer limits sand ingress to 100 grams per cubic metre, protecting internal components from premature wear.
Operating on a 415V three-phase supply, the 9.3 kW motor draws 20.5 Amps and achieves 72.7 metres of shut-off head. Flow capacity reaches 1000 L/Min through the 80 mm discharge outlet. Performance to EN ISO 9906 Grade 3B ensures reliable operation across the duty range.
Submersion depths up to 350 metres are supported by Class F insulation and IP68 protection. The Duplex stainless steel shaft and AISI 316L tie rods provide mechanical durability for continuous submerged service. Safety hook attachment points simplify installation, while NEMA motor compatibility facilitates assembly.
