Product Overview
Reliable operation in borehole water supply applications is achieved through the multistage hydraulic design of the ZN622/18-3, delivering high-volume pumping for industrial sectors. Specified for submerged service in 6-inch boreholes, the assembly manages clean water transfer where sand concentrations do not exceed 100 g/m³ during standard operation. The unit is suitable for vertical installation in reservoirs or deep underground sources to maintain distribution network pressure.
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 107 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 18.5 kW motor operates on a 415v supply with a rated current of 39.3 Amps. The pump achieves a maximum head of 241.9 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 network is made via Rp 2 1/2-inch threads 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 reaching 350 meters with compatible 6-inch L6W motors. Discharge ports include holes for safety hook attachment to ensure secure placement in deep borehole sites.
