ZAO Series Centrifugal Pumps
ZAO series centrifugal pumps share the same design as the ZA series and are designed for petroleum and chemical processing. The performance range covers capacities up to 2400m³/h at 1450 rpm and differential heads up to 250m at 2900 rpm with a maximum operating temperature of 180℃. With a wide selection of materials and the possibility of applying several shaft sealing systems, the pumps are able to transfer neutral or corrosive liquids, or liquids with few non-ferrous particles. They use mechanical seals specifically designed for harsh, abrasive and toxic fluids containing solid elements, including dirty fluids and high viscosity fluids.
