Replace Pump Seal See Supplemental pump Instructions.
NOTE : Due to the nature of the material used in Magnetic Particle Inspection, periodic maintenance is
required on the pump seal. Replacement is recommended every 3 months, based on using Magnaflux
materials for an 8 hour day, 5 days a week work schedule. It is recommended to maintain a back-up pump
that can be switched out when the seal needs to be changed in order to decrease the amount of downtime on
the machine.
Screen Cleaning
To prevent loss of flow from the pump, the screen on the intake of the pump will need to be cleaned on a
weekly basis. NOTE : Be sure the pump is turned off prior to removing the sump screen. To remove the
screen, simply push in and twist the brass fitting one quarter turn and pull off along with a spring. In Figure 4-1
below, this shows the entire assembly assembled. Figure 4-2 shows the brass fitting removed.
