Product Overview
Reliable operation in high-volume irrigation water supply systems is achieved through the multistage hydraulics of the ZN622/18-3N, delivering high-volume pumping for industrial duties. Specified for vertical installation in 6-inch wells, the assembly manages clean water transfer where sand concentrations do not exceed 100 g/m³ in reservoirs or deep source sites. The unit provides a consistent source of pressurized water for high-volume agricultural and civil distribution networks.
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 107 kg and operates in liquids from -10°C to 60°C. Every wetted internal surface features corrosion-resistant alloys to ensure technical consistency in high-temperature industrial duties.
The 18.5 kW motor operates on a 415v supply with a rated current of 39.3 Amps. The pump achieves a maximum head of 241.9 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 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 motors. Discharge ports include microcast holes for safety hook attachment to ensure secure placement in deep borehole sites.
