Product Overview
Reliable operation in deep boreholes is achieved through the multistage hydraulic design of the 4ZN622/3-3, which delivers high-volume pumping for irrigation and supply systems. Specified for submerged service in 6-inch wells, the assembly manages clean water transfer where sand particles do not exceed 100 g/m³. The unit is suitable for vertical installation in reservoirs or boreholes to provide a consistent pressurized source for residential and industrial sectors.
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 in the fluid stream. The unit weighs 31 kg and operates in liquids from -10°C to 60°C. Every wetted internal surface features corrosion-resistant alloys for use in high-temperature applications.
The 3 kW motor operates on a 415v supply with a rated current of 7.64 Amps. The pump achieves a maximum head of 40.8 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 head designed for system integration.
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 300 meters with compatible 4-inch C4S motors. Discharge ports include holes for safety hook attachment to facilitate secure placement in borehole sites.
