Centrifugal pump Z6

waterwith asynchronous motorsubmersible

Product overview
Multistage deep well pumps of the Z6 and ZN6 series are designed to pump clean or slightly sandy water (maximum sand content 1050 g/m³). The pumps are made for 6″ well casings (maximum pump diameter 142 mm). The Z6 range offers nominal flow options of 12, 16, 22, 31, 46 and 60 m³/h. Z6 components are AISI 304 stainless steel; ZN6 components are AISI 316 stainless steel, providing compact, corrosion-resistant construction suitable for chemically non-aggressive fluids.
