Product Overview
Agricultural irrigation and groundwater supply for farming require pumps with high head capability and sustained performance. The Lowara ZN631/20-3 delivers 667 L/Min from its 6-inch wet end with 6-inch motor, achieving 287.6 metres of shut-off head. The microcast stainless steel housing ensures long-term durability.
Wear ring replacement is facilitated by the removable impeller design. AISI 316 stainless steel throughout the wet end provides corrosion resistance. The suction strainer limits sand ingress to 100 grams per cubic metre. The integrated non-return valve prevents backflow. The Duplex shaft provides mechanical strength.
Operating on 415V three-phase supply, the motor draws 54.2 Amps and achieves 287.6 metres of shut-off head. Flow capacity is 667 L/Min through the Rp 3 discharge outlet. Performance complies with EN ISO 9906 Grade 3B tolerances.
Immersion depths to 350 metres are supported with Class F insulation and IP68 rating. AISI 316L tie rods offer structural support. NEMA compatibility and safety hook holes facilitate installation.
