Product Overview
Municipal water distribution networks require pumps with consistent hydraulic performance and corrosion-resistant construction. The Lowara ZN631/4-3 combines a 6-inch wet end with 6-inch motor, achieving 667 L/Min for continuous water delivery. The microcast stainless steel housing provides long-term structural integrity.
Suction strainer design limits sand passage to 100 grams per cubic metre, preserving internal clearances. 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.
Driven by 415V three-phase supply drawing 12.7 Amps, shut-off head reaches 57.9 metres. Flow capacity is 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 and AISI 316L tie rods provide mechanical durability. NEMA compatibility and safety hook holes simplify borehole installation.
