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.\u003c\/p\u003e\u003cp\u003eAISI 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.\u003c\/p\u003e\u003cp\u003eOperating on a 415V three-phase supply, the 7.5 kW motor draws 17 Amps and achieves 42.8 metres of shut-off head.
