Product Overview
Agricultural irrigation networks demand pumps that move significant water volumes while enduring continuous submersion. The Lowara 4ZN631/2-3 pairs a 6-inch wet end with a 4-inch motor, delivering 667 litres per minute for farm water distribution. Its radial flow design maintains consistent output across varying field conditions.
Material selection begins with AISI 316 stainless steel throughout the wet end, protecting against corrosive groundwater. The suction strainer restricts sand ingress to 100 grams per cubic metre, preserving internal clearances. A removable wear ring on the impeller simplifies maintenance, while the non-return valve prevents column backflow during motor shutdown.
Electrical supply is three-phase 415V with a 7.6 Amp draw. Maximum head reaches 28.8 metres at shut-off, with flow capacity of 667 L/Min through the Rp 3 discharge port. Performance testing follows EN ISO 9906 Grade 3B standards.
Class F insulation and IP68 rating permit installation to 300 metres depth. The Duplex stainless steel shaft and AISI 316L tie rods provide structural integrity. Safety hook holes and NEMA coupling facilitate borehole installation and motor assembly.
