Product Overview
Irrigation systems and agricultural water distribution require pumps with consistent flow and corrosion-resistant construction. The Lowara ZN631/4-3N combines a 6-inch wet end with 6-inch motor and NEMA coupling, achieving 667 L/Min for farm water supply. The multi-stage hydraulic assembly provides stable performance.
Non-return valve integration prevents water column backflow during power interruptions. AISI 316 stainless steel throughout the wetted components offers corrosion resistance. The impeller incorporates a removable wear ring. The suction strainer restricts sand passage to 100 grams per cubic metre. The Duplex shaft provides torsional strength.
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. AISI 316L tie rods provide mechanical reinforcement. NEMA compatibility and safety hook holes simplify borehole installation.
