Product classification

ZA, ZAK, ZAG Series Petrochemical Process Pumps

This series of pumps features closed and semi-open impellers with balance and wear rings to balance axial thrust, while open impellers use back vanes for axial thrust balance. Pumps with discharge diameters above 80 mm are designed with double volute casings to balance radial forces, ensuring bearing longevity and stable operation at the shaft seal. Bearings are paired as cylindrical roller or tapered roller bearings according to different operating conditions to improve service life.
