Product Overview
Groundwater pumping for municipal supply and agricultural irrigation demands pumps with high head capability and reliable performance. The Lowara ZN631/12-3 handles these duties with a 6-inch wet end and 6-inch motor, processing 667 L/Min for water extraction. Its radial flow impeller arrangement ensures efficient hydraulic performance.
Suction strainer design limits sand passage to 100 grams per cubic metre, preserving internal clearances. 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 Duplex stainless steel shaft provides torsional strength.
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. AISI 316L tie rods provide structural reinforcement. Safety hook holes and NEMA coupling simplify installation.
