Product Overview
Continuous extraction for borehole water supply in industrial and agricultural sectors is the primary duty of the ZN622/7-3 bore pump. The unit is designed for submerged operation inside 6-inch boreholes to provide a steady pressurized supply of clean water for high-volume distribution. This model handles clean water with sand concentrations up to 100 g/m³ in reservoirs or wells while maintaining stable hydraulic performance in aggressive environments.
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. The unit weighs 64 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 7.5 kW motor operates on a 415v supply with a rated current of 17.6 Amps. The pump achieves a maximum head of 95.1 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 piping system is made through Rp 2 1/2-inch threads on the microcast 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 motors. Discharge ports include microcast holes for safety hook attachment to facilitate secure installation in borehole sites.
