Product Overview
Industrial dewatering and civil engineering projects require pumps that sustain high flow rates under continuous operation with minimal maintenance. The Lowara ZN660/3-3 processes 1300 L/Min from its 6-inch wet end with 6-inch motor, handling large volumes for mine dewatering and construction site drainage. The radial flow impeller arrangement ensures efficient hydraulic performance across the operating range.
AISI 316 stainless steel construction protects the wet end 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 clearances. The discharge head incorporates safety hook holes for secure borehole installation.
Driven by a 5.5 kW three-phase motor at 415V, the pump draws 12.7 Amps and achieves 31.9 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 to 350 metres. The Duplex stainless steel shaft and AISI 316L tie rods provide mechanical durability. NEMA motor coupling simplifies assembly, and the microcast stainless steel construction ensures long-term structural integrity.
