Product Overview
Continuous extraction from deep wells for groundwater dewatering identifies the primary application for the ZN622/8-3N bore pump, featuring full AISI 316 construction. Technical configuration supports permanent vertical installation in 6-inch boreholes to provide a reliable source of clean water for industrial and agricultural distribution. The unit handles clean fluids containing sand concentrations up to 100 g/m³ while maintaining stable hydraulic behavior in corrosive underground wells.
Constructed from AISI 316 Stainless Steel, the housing surrounds internal components designed for immersion in corrosive 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 66 kg and operates in liquids from -10°C to 60°C. Every wetted internal surface features corrosion-resistant alloys to maintain stable performance in aggressive conditions.
The 7.5 kW motor operates on a 415v supply with a rated current of 17.6 Amps. The pump achieves a maximum head of 108.7 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 L6C motors. Discharge ports include microcast holes for safety hook attachment to facilitate secure installation in deep borehole sites.
