Product Overview
Supplying fountain waterworks and pressurized distribution systems from underground reservoirs is the intended duty of the ZN622/5-3 bore pump. Technical configuration supports submerged service in 6-inch boreholes to provide a continuous source of clean water for industrial and residential use. This model handles clean fluids containing suspended sand concentrations up to 100 g/m³ while maintaining stable hydraulic behavior in aggressive groundwater conditions.
Constructed from AISI 316 Stainless Steel, the housing surrounds internal components designed for aggressive environments. The radial centrifugal impeller, manufactured from AISI 316L stainless steel, processes solids up to 2 mm in the fluid stream. The unit weighs 57 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 5.5 kW motor operates on a 415v supply with a rated current of 12.7 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 located 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 350 meters with compatible 6-inch L6W motors. Discharge ports include microcast holes for safety hook attachment to facilitate secure installation in deep wells.
