Product Overview
Reliable operation in high-volume irrigation systems defines the application scope for the ZN622/12-3, providing dependable transfer from deep borehole sources. Technical design aligns with permanent vertical installation in 6-inch boreholes to support agricultural distribution and pressurized supply systems. The unit handles clean water environments where suspended sand particles do not exceed 100 g/m³ while maintaining stable hydraulic behavior in aggressive groundwater.
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 78 kg and operates in liquids from -10°C to 60°C. Every wetted internal surface features corrosion-resistant alloys to ensure technical consistency in 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 161.6 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 made through 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 motors. Discharge ports include microcast holes for safety hook attachment to facilitate secure installation in deep wells.
