Product Overview
Continuous extraction from underground wells for water feature supply defines the primary duty for the ZN622/19-3N bore pump, featuring full AISI 316 construction. Configuration supports permanent vertical installation in 6-inch boreholes to provide a reliable source of clean water for industrial and municipal distribution networks. The unit handles clean fluids containing suspended sand concentrations up to 100 g/m³ while maintaining stable hydraulic behavior in corrosive sites.
Constructed from AISI 316 Stainless Steel, the housing surrounds internal components designed for immersion in 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 109 kg and operates in liquids from -10°C to 60°C. Every wetted internal surface features corrosion-resistant alloys to ensure technical consistency in aggressive environments.
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 255.3 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 reaching 350 meters with compatible 6-inch motors. Discharge ports include microcast holes for safety hook attachment to facilitate secure installation in borehole sites.
