Product Overview
High-capacity transfer from deep underground sources defines the operational profile of the ZN622/24-3, supporting borehole water supply for industrial distribution. The technical design aligns with vertical installation in 6-inch boreholes to maintain a consistent pressurized supply for agricultural and civil distribution systems. The unit handles clean water environments where suspended sand particles do not exceed 100 g/m³ in reservoirs or deep well 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 121 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 duties.
The 22 kW motor operates on a 415v supply with a rated current of 46.6 Amps. The pump achieves a maximum head of 321 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 distribution network is via 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 up to 350 meters with compatible 6-inch motors. Discharge ports include microcast holes for safety hook attachment to facilitate secure installation in deep wells.
