Life of these components tends to be extended when the requirements in "4.1 Cautions for
Operation" are followed, and the pump is operated under a light load. The term 'light load'
refers to operation at achieved pressure (inlet closed).
Bearings are replaced by the manufacturer
’s service division.
< Guidelines for Replacement and Cleaning >
Replace or clean components if performance is reduced and/or the following symptoms
appear.
Backup inlet and outlet valves:
Replace in the event of abnormal wear, hardening, or cracking.
Cup packing:
Replace in the event of abnormal wear, hardening, or cracking.
Inlet and outlet valves:
Replace in the event of deformation, hardening, or chipping.
Bearings:
Contact the manufacturer for repair in the event of abnormal noises or
abnormal motor vibration (chattering).
Inlet valve rubber separator:
Replace in the event of deformation, wear, hardening, or cracking.
Connecting tubes: Replace in the event of deformation, wear, hardening, or cracking.
Gaskets:
Replace in the event of deformation, hardening, or cracking.
