Product Overview
Reliable operation in water feature supply and large-scale distribution systems is achieved through the multistage hydraulic design of the ZN622/8-3 bore pump. Specified for vertical installation in 6-inch boreholes, the unit manages clean water transfer duties where sand particles do not exceed 100 g/m³. The assembly provides a consistent pressurized supply from reservoirs or deep underground sources for irrigation and industrial sectors.
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 66 kg and operates in liquids from -10°C to 60°C. Every wetted internal surface features corrosion-resistant alloys to ensure technical consistency during continuous duty pumping.
The 7.5 kW motor operates on a 415v supply with a rated current of 17.6 Amps. The pump achieves a maximum head of 108.7 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 up to 350 meters with compatible 6-inch L6W motors. Discharge ports include holes for safety hook attachment to facilitate secure placement in borehole environments.
