The Lowara 4ZN631\/6-3 pairs a 6-inch wet end with a 4-inch motor, delivering 667 L\/Min for demanding water transfer applications. The hydraulic stages maintain stable performance across varying duty cycles.\u003c\/p\u003e\u003cp\u003eWear ring replacement is simplified by the removable design, reducing maintenance downtime. AISI 316 stainless steel construction throughout the wet end provides corrosion resistance in aggressive groundwater. The suction strainer limits sand ingress to 100 grams per cubic metre. Non-return valve integration prevents backflow when the motor stops.\u003c\/p\u003e\u003cp\u003eOperating on 415V three-phase supply, the motor draws 17.9 Amps and achieves 86.9 metres of shut-off head. Flow capacity is 667 L\/Min through the Rp 3 discharge outlet. Performance testing to EN ISO 9906 Grade 3B ensures reliable operation.\u003c\/p\u003e\u003cp\u003eClass F insulation and IP68 rating support immersion to 300 metres. The Duplex stainless steel shaft provides mechanical strength, while AISI 316L tie rods offer structural support.
