Industrial dewatering and civil pressure boosting applications require pumps that sustain high flow rates under continuous operation. The Lowara 4ZN660/2-3 processes 1300 L/Min through its 6-inch wet end with 4-inch motor connection, handling large volumes for construction site dewatering and municipal water transfer projects. The radial flow impeller arrangement delivers efficient hydraulic performance across the operating range.
Corrosion resistance comes from AISI 316 stainless steel throughout the wet end, protecting internal components from aggressive groundwater. The impeller includes a removable wear ring for maintenance access without complete disassembly. The suction strainer limits suspended sand to 100 grams per cubic metre, safeguarding internal clearances. The integrated non-return valve prevents reverse flow during motor shutdown, while safety hook holes facilitate installation and retrieval.
Power comes from a 4 kW three-phase motor at 415V drawing 10.2 Amps. Maximum head reaches 21 metres at shut-off with flow capacity of 1300 L/Min through the 80 mm discharge port. Hydraulic performance meets EN ISO 9906 Grade 3B tolerances for reliable operation across varying duty points.
Class F insulation with IP68 rating supports immersion to 300 metres. The Duplex stainless steel shaft and AISI 316L tie rods provide mechanical durability. NEMA motor compatibility simplifies assembly, and the microcast stainless steel construction ensures long-term structural integrity in demanding applications.
