Product Overview
Handling groundwater dewatering and high-capacity transfer from deep borehole sites defines the application scope for the ZN622/6-3 submersible pump. It is suitable for permanent vertical installation in 6-inch boreholes to provide a high-volume source for distribution networks and industrial process water. Technical configuration supports clean water transfer where sand particles do not exceed 100 g/m³ in reservoirs or deep underground sources.
Constructed from AISI 316 Stainless Steel, the housing surrounds internal components designed for immersion in aggressive groundwater. The radial centrifugal impeller, manufactured from AISI 316L stainless steel, processes solids up to 2 mm. The unit weighs 59 kg and operates in liquids from -10°C to 60°C. Every wetted internal surface features corrosion-resistant alloys to ensure technical consistency in industrial applications.
The 5.5 kW motor operates on a 415v supply with a rated current of 12.7 Amps. The pump achieves a maximum head of 81.6 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 350 meters with compatible 6-inch motors. Discharge ports include holes for safety hook attachment to facilitate secure placement in deep borehole environments.
