Product Overview
High-capacity water transfer from deep boreholes defines the duty of the 4ZN622/5-3, supporting pressure boosting and groundwater supply where dependable continuous operation is required. The technical design aligns with vertical installation in 6-inch boreholes to provide a steady pressurized source for industrial and agricultural distribution. The unit handles clean water with sand concentrations up to 100 g/m³ in reservoirs or deep well sites.
Constructed from AISI 316 Stainless Steel, the housing surrounds internal components designed for aggressive groundwater conditions. The radial centrifugal impeller, manufactured from AISI 316L stainless steel, processes solids up to 2 mm in the fluid stream. The unit weighs 44 kg and operates in liquids from -10°C to 60°C. Every wetted internal surface features corrosion-resistant alloys to maintain stable hydraulic performance.
The 5.5 kW motor operates on a 415v supply with a rated current of 12.6 Amps. The pump achieves a maximum head of 68 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 up to 300 meters with compatible C4S motors. Discharge ports include holes for safety hook attachment to ensure secure placement in deep borehole environments.
