Product Overview
Borehole groundwater supply installations need pumps with robust construction and dependable performance characteristics. The Lowara ZN631/3-3 features a 6-inch wet end with 6-inch motor, delivering 667 L/Min for continuous water extraction. The multi-stage hydraulic assembly provides stable output across varying demand conditions.
Tie rods constructed from AISI 316L stainless steel brace the external structure, ensuring alignment during operation. The impeller incorporates a removable wear ring for maintenance access. AISI 316 stainless steel throughout the wet end offers corrosion resistance. The suction strainer restricts sand to 100 grams per cubic metre, protecting internal components.
A 415V three-phase supply powers the motor drawing 9.2 Amps, delivering 43.2 metres of shut-off head. Flow capacity reaches 667 L/Min through the Rp 3 discharge 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 stainless steel shaft provides mechanical durability. NEMA motor compatibility and safety hook holes simplify installation.
