Water distribution networks and municipal supply systems require pumps with high head capability and consistent performance. The Lowara ZN631/17-3 delivers 667 L/Min from its 6-inch wet end with 6-inch motor, achieving 244.5 metres of shut-off head. The microcast stainless steel housing provides structural integrity.
Suction strainer design limits sand passage to 100 grams per cubic metre. AISI 316 stainless steel throughout the wetted components offers corrosion resistance. The non-return valve secures the water column against reverse flow. The impeller incorporates a removable wear ring. The Duplex shaft provides torsional strength.
Operating on 415V three-phase supply, the motor draws 46.6 Amps and delivers 244.5 metres of shut-off head. Flow capacity reaches 667 L/Min through the Rp 3 outlet. Hydraulic performance conforms to EN ISO 9906 Grade 3B tolerances.
Immersion depths to 350 metres are supported with Class F insulation and IP68 rating. AISI 316L tie rods provide mechanical reinforcement. NEMA compatibility and safety hook holes simplify borehole installation.
