Product Overview
Reliable operation in high-capacity water feature supply systems is achieved through the multistage radial hydraulics of the ZN622/30-3, providing dependable transfer from deep wells. Technical configuration supports permanent vertical installation in 6-inch boreholes to support distribution networks and industrial process water needs. The unit handles clean water containing suspended sand concentrations up to 100 g/m³ while maintaining hydraulic behavior in reservoirs.
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 156 kg and operates in liquids from -10°C to 60°C. Every wetted internal surface features corrosion-resistant alloys for technical consistency in high-temperature applications.
The 30 kW motor operates on a 415v supply with a rated current of 61.7 Amps. The pump achieves a maximum head of 401.3 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 to the system is via Rp 2 1/2-inch threads located 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.
