Centrifugal Pump · Pumps
Maintaining reliable performance is crucial for any marine-rated pump handling chemicals, oil, or water. Teikoku Electric Mfg.’s R Series, featuring a canned motor pump design and electric drive, requires vigilant monitoring to prevent common failures such as sleeve bearing wear from poor liquid lubrication and stator liner corrosion. During regular maintenance or when experiencing abnormal noise or current fluctuations, inspect the bearings and liners. Critical spares include sleeve bearings, thrust bearing parts, gaskets, rotor/stator can components, and terminal box seals. Regular checks of motor current, temperature, and differential pressure, along with avoiding dry running conditions, are essential to prolonging the pump’s service life.
