Product Overview
Municipal groundwater supply and industrial extraction require pumps that combine high head capability with corrosion resistance. The Lowara ZN631/9-3 delivers 667 L/Min from its 6-inch wet end with 6-inch motor, achieving 130.8 metres of shut-off head for deep well applications. The multi-stage hydraulic assembly provides stable performance.
Sand ingress is controlled by the suction strainer, limiting passage to 100 grams per cubic metre. AISI 316 stainless steel throughout the wet end offers corrosion resistance. The impeller incorporates a removable wear ring for maintenance access. The integrated non-return valve prevents reverse flow.
Driven by 415V three-phase supply drawing 23.1 Amps, shut-off head reaches 130.8 metres. Flow capacity is 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 and AISI 316L tie rods provide mechanical durability. NEMA motor compatibility and safety hook holes simplify installation.
