The oxidation of steel elements in process systems produces magnetite particles, which cause a decrease in the efficiency and potential failure of the process systems. The size of magnetite particles obtained from a real system is analyzed. Particular attention is paid to increasing the resistance to the accumulation of the magnetite particles in the centrifugal pump, as a typical element of the process system. The basic measure is to optimally reduce the volumetric flow of water through the rotor assembly with a calculation model and experimental validation. With visualization, the deaeration ability is verified. Additional measures are based on the principles of separation of particles of magnetite prior to entry into the rotor assembly. For all examples, the pump's characteristic curves are measured and a long term test with magnetite particles is performed. The most effective measure is to use a filter that does not impair the characteristic curves while reducing the accumulation of magnetite in the rotor assembly by 20 % and reducing the bearing wear by an average of 98 % compared to the reference pump.
