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.
