Operation and Maintenance Manual 2.3.3. Gauges For the operation control, it is recommended to provide a compound gauge on the suction pipe line and a pressure gauge at the pump casing or close to the casing on the discharge pipe line. These gauges shall be able to indicate the pressure equivalent to about 150% of the maximum operating pressure. - Page 10 Operation and Maintenance Manual Clean adequately each pump component / parts. Prevent adhesion of dust on the connections and joint portions. When replacing the ball bearings, use the designated bearing No. (63 series, LLU-C3) without fail and fit them in the pump shaft by shrinkage-fit after warming them in heated oil of 110 °C ~ 120 °C. Take good care not to damage each gasket and the sealed contact surface of each parts.
