Product Overview
Continuous groundwater extraction from deep wells and reservoirs is the primary application for the 4ZN622/2-3, which handles clean water containing sand concentrations up to 100 g/m³. Technical configuration supports permanent vertical installation in 6-inch boreholes for industrial and agricultural distribution networks. The unit maintains stable hydraulic performance across its operating range while managing water transfer duties for civil works and high-volume supply systems.
Constructed from AISI 316 Stainless Steel, the housing surrounds internal components designed for aggressive groundwater environments. The radial centrifugal impeller, manufactured from AISI 316L stainless steel, processes solids up to 2 mm in the fluid stream. The unit weighs 24 kg and operates in liquids from -10°C to 60°C. Every wetted internal surface features corrosion-resistant alloys for use in high-temperature fluid handling applications.
The 2.2 kW motor operates on a 415v supply with a rated current of 5.6 Amps. The pump achieves a maximum head of 27.2 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 to the system is made through Rp 2 1/2-inch threads located 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 300 meters with compatible C4S motors. Discharge ports include microcast holes for safety hook attachment to facilitate secure installation in deep borehole sites.
