Product Overview
Deep well extraction for industrial water supply and irrigation requires pumps with high head capability and sustained performance. The Lowara ZN631/11-3 delivers 667 L/Min from its 6-inch wet end with 6-inch motor, achieving 159.8 metres of shut-off head. The microcast stainless steel housing provides structural integrity for demanding applications.
Tie rods constructed from AISI 316L stainless steel brace the external structure. The non-return valve secures the water column against reverse flow. AISI 316 stainless steel throughout the wetted components offers corrosion resistance. The impeller incorporates a removable wear ring for maintenance access. The suction strainer restricts sand passage to 100 grams per cubic metre.
Operating on 415V three-phase supply, the motor draws 32.2 Amps and delivers 159.8 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. The Duplex shaft provides mechanical durability. NEMA compatibility and safety hook holes simplify borehole installation.
