Product Overview
Specified for high-volume agricultural irrigation from deep boreholes, the ZN622/4-3 maintains a steady supply of clean water while handling sand concentrations up to 100 g/m³. The unit is configured for submerged operation inside 6-inch boreholes to support large-scale irrigation systems and water feature supply. Its technical design provides consistent pressurized transfer from underground sources to surface distribution networks in civil and industrial sectors.
Constructed from AISI 316 Stainless Steel, the housing surrounds internal components designed for aggressive groundwater. The radial centrifugal impeller, manufactured from AISI 316L stainless steel, processes solids up to 2 mm. The unit weighs 54 kg and operates in liquids from -10°C to 60°C. Every wetted internal surface features corrosion-resistant alloys to maintain stable hydraulic performance in industrial duties.
The 4 kW motor operates on a 415v supply with a rated current of 9.17 Amps. The pump achieves a maximum head of 54.2 m and a maximum flow of 500 L/Min through a 65 mm discharge outlet. Multistage radial hydraulics provide efficient water delivery throughout the operating range. Connection is made through Rp 2 1/2-inch threads on the microcast discharge head.
The pump features a duplex stainless steel shaft protected by shaft sleeves and tungsten carbide bushings. An integrated stainless steel non-return valve prevents backflow, while removable wear rings simplify servicing. The assembly supports installation depths reaching 350 meters with compatible 6-inch L6W motors. Discharge ports include microcast holes for safety hook attachment to facilitate secure placement in deep borehole sites.
