Product Overview
Corrosion resistance is central to the construction of the ZN622/4-3N, combining a 316 stainless steel wet end and motor for aggressive groundwater supply duties. Specified for permanent vertical installation in 6-inch boreholes, the unit manages clean water transfer where sand particles do not exceed 100 g/m³. Technical configuration supports submerged service to provide a steady pressurized supply for irrigation and industrial distribution networks from deep sources.
Constructed from AISI 316 Stainless Steel, the housing surrounds internal components designed for immersion in aggressive or corrosive 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 for use in high-temperature fluid handling applications.
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 up to 350 meters with compatible 6-inch L6C motors. Discharge ports include holes for safety hook attachment during installation in deep borehole environments.
