Inspection and Repair
Should it be necessary to remove the pump from service for periodic inspection of components and/or a major repair, the following
steps should be taken. See following pages for exploded pump views and instructions.
WARNING
Failure to follow these instructions could result in serious bodily injury or death. Do not attempt to work on any Tuthill pump installation
before completing the steps below. Only authorized personnel who are familiar with the repair of mechanical products should perform
the necessary repair work. You must familiarize yourself with the entire contents of this manual prior to performing any work.
Disconnect the drive so that it cannot be started while work is being performed.
Review the Material Safety Data Sheet (MSDS) applicable to the liquid being pumped to determine its characteristics and the precautions
necessary to ensure safe handling.
Vent all pressure within the pump through the suction or discharge lines. Ensure that the pump has cooled to a safe temperature prior
to performing any work on the pump.
