Product Overview
High-volume municipal waterworks and agricultural irrigation networks need pumps that sustain performance under continuous load. The Lowara 4ZN660/4-3 delivers 1300 L/Min from its 6-inch wet end with 4-inch motor connection, providing reliable water transfer for city supply systems and large-scale farming operations. The radial flow hydraulic design ensures efficient energy transfer across the operating range.
The pump incorporates AISI 316 stainless steel throughout the wet end, protecting every component from corrosion and abrasive wear. The impeller includes a removable wear ring for simplified maintenance access. The integrated non-return valve prevents water column reversal during shutdown. The suction strainer limits suspended sand to 100 grams per cubic metre, preserving internal component integrity. Safety hook holes on the discharge head enable secure handling during installation.
Driven by a 7.5 kW three-phase motor at 415V, the pump draws 18.1 Amps and achieves 42.8 metres of shut-off head. Flow capacity is 1300 L/Min through the 80 mm discharge port. Performance complies with EN ISO 9906 Grade 3B tolerances for consistent hydraulic output.
Class F insulation with IP68 rating supports immersion depths to 300 metres. The Duplex stainless steel shaft and AISI 316L tie rods provide mechanical durability. NEMA motor coupling simplifies assembly, and the microcast stainless steel head and motor support provide structural integrity for demanding applications.
