Pump Care and Maintenance
NOTE: Due to the nature of the material used in Magnetic Particle Inspection, periodic mainte-
nance 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.
The life of the pump and pump seal can be maximized if contamination is not introduced into
the machine’s inspection bath. Contamination may include but not limited to grinding dust, tool-
ing oil or coolant, metal shavings, wheelabrator/sandblasting residue and paint chips.
Ways to prevent contamination include locating the machine in a dedicated room, providing
positive air pressure inside the Equipment Enclosure (Hood Assembly) , keeping the front cur-
tain of the Equipment Enclosure closed, and thoroughly cleaning parts before they are subject-
ed to testing.
Signs of contamination:
1. Settling time exceeds either 30 minutes (water) or 60 minutes for Carrier II (Oil)
2. 2nd layer (lighter in color) appears in centrifuge tube (Spec. is less than 30%)
3. Oil bath turning a “milky white” color (water/coolant contamination)
Examples of contaminated pumps:
