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.\u003c\/p\u003e\u003cp\u003eCorrosion 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.\u003c\/p\u003e\u003cp\u003eOperating 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.\u003c\/p\u003e\u003cp\u003eSubmersion 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.
