What our service work and the manufacturer documentation say about keeping this model running.
Inspect bearings, lubrication, seals, couplings, foundations, process connections and protective devices. Trend vibration, temperature, pressure, flow and motor load where available and investigate deterioration from the established normal condition. Check for leakage, corrosion, fouling and abnormal mechanical contact. Function-test local and remote controls, alarms and shutdowns after maintenance. Maintain cleanliness during opening and reassembly. Refer to the manufacturer documentation for the exact figure for clearances, limits, settings and overhaul criteria.
Keep model-correct seals, gaskets, bearings, filters or strainers, coupling parts, sensors and manufacturer-recommended wear components. Critical installations may justify a rotating assembly, motor or control module according to redundancy. Confirm all parts against the exact model and serial number.
