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.\u003c\/p\u003e\u003cp\u003eProtection 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.\u003c\/p\u003e\u003cp\u003ePower 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.\u003c\/p\u003e\u003cp\u003eImmersion depths to 350 metres are supported with Class F insulation and IP68 rating.
