Product Overview
Supplying groundwater for industrial distribution systems from deep wells identifies the primary duty for the ZN622/11-3N, featuring full AISI 316 wet end and motor construction. Technical configuration supports permanent vertical installation in 6-inch boreholes to provide a consistent pressurized supply for agricultural and distribution networks. The unit handles clean fluids containing suspended sand concentrations up to 100 g/m³ in deep underground wells or reservoirs.
Constructed from AISI 316 Stainless Steel, the housing surrounds internal components designed for corrosive groundwater environments. The radial centrifugal impeller, manufactured from AISI 316L stainless steel, processes solids up to 2 mm in the fluid stream. The unit weighs 76 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 industrial applications.
The 11 kW motor operates on a 415v supply with a rated current of 23.1 Amps. The pump achieves a maximum head of 148.1 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 located 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 microcast holes for safety hook attachment during installation in deep borehole sites.
