Groundwater extraction for irrigation and municipal supply requires pumps with high head capability and sustained performance. The Lowara ZN631/12-3N handles these duties with a 6-inch wet end and 6-inch motor with NEMA coupling, processing 667 L/Min for water extraction. Its radial flow impeller arrangement ensures efficient hydraulic performance.
Coupling replacement is straightforward with the standardized NEMA design. AISI 316 stainless steel construction protects the wet end from corrosion. The impeller includes a removable wear ring. The integrated non-return valve prevents water column reversal. The suction strainer limits suspended sand to 100 grams per cubic metre.
Driven by 415V three-phase motor drawing 39.3 Amps, shut-off head reaches 174.8 metres. Flow capacity is 667 L/Min through the Rp 3 discharge port. Performance complies with EN ISO 9906 Grade 3B tolerances.
Class F insulation with IP68 rating supports immersion to 350 metres. The Duplex stainless steel shaft and AISI 316L tie rods provide mechanical durability. Safety hook holes simplify installation.
