Groundwater extraction for agricultural irrigation and municipal supply requires pumps that move substantial volumes reliably. The Lowara 4ZN660/1-3 delivers 1300 litres per minute through a 6-inch wet end with 4-inch motor connection, handling high-volume water transfer across farmlands and distribution networks. The radial flow hydraulic configuration maintains consistent output across varying demand conditions.
AISI 316 stainless steel construction throughout the wet end provides corrosion resistance against aggressive groundwater chemistry. The suction strainer restricts sand ingress to 100 grams per cubic metre, preserving internal clearances. The impeller incorporates a removable wear ring for straightforward maintenance, while the integrated non-return valve prevents water column backflow. The discharge head includes safety hook holes for secure borehole installation.
Driven by a 2.2 kW three-phase motor at 415V, this unit draws 5.6 Amps under normal operation. Maximum head reaches 10 metres at shut-off, with flow capacity of 1300 L/Min through the 80 mm discharge port. Performance complies with EN ISO 9906 Grade 3B tolerances, ensuring predictable operation across the duty range.
Class F insulation and IP68 rating support installation depths to 300 metres with C4S motors. The Duplex stainless steel shaft and AISI 316L tie rods provide mechanical strength for continuous submerged service. NEMA motor coupling compatibility simplifies assembly, and the microcast stainless steel head and motor support provide structural integrity.
