Overview HZA and HZE series petrochemical process pumps are horizontal, radially split, single-stage cantilevered centrifugal pumps with a volute-type pump body. They are designed and manufactured for the Petroleum, Refinery, and Gas Industry. This series has been carefully engineered in terms of support, connection, bearing, cooling, and other structural aspects to ensure high safety, reliability, and long service life.
Design These pumps can be equipped with various auxiliary and monitoring systems to ensure ease of maintenance and interchangeability of parts. They feature excellent hydraulic performance, high efficiency, and superior cavitation resistance, making them high-efficiency and energy-saving products. The sealing system is designed for Centrifugal and Rotodynamic Pump Shaft Seal Systems, suitable for various complex operating conditions.
