Product Overview
Specified for high-pressure boosting duties from deep borehole sites, the ZN622/16-3 bore pump provides a continuous source for industrial and agricultural distribution systems. Technical configuration supports permanent vertical installation in 6-inch boreholes to manage clean water transfer where sand particles do not exceed 100 g/m³. The unit provides a consistent pressurized supply from reservoirs or deep underground wells for civil distribution networks.
Constructed from AISI 316 Stainless Steel, the housing surrounds internal components designed for aggressive groundwater environments. The radial centrifugal impeller, manufactured from AISI 316L stainless steel, processes solids up to 2 mm. The unit weighs 92 kg and operates in liquids from -10°C to 60°C. Every wetted internal surface features corrosion-resistant alloys to ensure technical consistency in corrosive environments.
The 15 kW motor operates on a 415v supply with a rated current of 32.2 Amps. The pump achieves a maximum head of 215.5 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 reaching 350 meters with compatible 6-inch L6W motors. Discharge ports include microcast holes for safety hook attachment to facilitate secure installation in deep borehole sites.
