ZA、ZAK、ZAG、Petrochemical process pump

           The closed and semi-open impellers of this series of pumps utilize a balanced wear ring to counterbalance the axial forces, while the open impellers employ back blades for the same purpose. For pumps with an outlet diameter exceeding 80mm, a double volute design is implemented to balance radial forces, thereby ensuring the longevity of the bearings and minimizing disturbances at the shaft seal. Bearings are selected based on working conditions, featuring combinations of cylindrical roller and tapered roller bearings, which significantly enhances bearing service life.

          Product implementation standards: APl610 (10th edition), VDMA24297

          ZA/ZAK/ZAG series of petrochemical process pump is horizontal, single stage, single suction, cantilever type centrifugal pump, products comply with standards DiN24256, 102858, G85662-85.

Mainly used in oil refinery, petrochemical industry, low temperature engineering, coal mining industry, chemical and general industrial processes, power plants, large and medium-sized heating and air conditioning equipment, environmental protection equipment, offshore industry and seawater desalination plants.
