Flowserve - Nuclear Vertical Pump (MEV)

This nuclear vertical pump features a bottom suction and side discharge configuration, designed specifically for essential service water applications in fossil and nuclear power plants. It is compliant with ASME Section III, Class 3 standards, ensuring suitability for critical environments. The pump is equipped with a standard cartridge mechanical seal for simplified maintenance and grease-lubricated bearings for reliable operation. Roller guide bearings above the seal minimize vibration, enhancing seal longevity, while back-to-back ball thrust bearings handle both up-thrust and down-thrust. The spacer coupling allows for bearing and seal replacement without removing the motor, supporting efficient service routines.
