ProTech and Competitive Seals were subjected to three extreme in-house tests with ProTech clearly the seal of choice.
They are,
- 1. Oil Leakage Test
- 2. Water Exclusion Test
- 3. Dust Exclusion Test
1. Oil Leakage Test
ProTech and other seals were subjected to critical oil seal testing using a test machine built to SAE J110 standards. One-hundred hour tests were conducted with severe oil splash.
2. Water Exclusion Test
The test machine was modified by mounting five nozzles at various positions relative to the exterior of the seal to simulate a most severe external hose down. Using water at pressures of 30 to 62 psi, these nozzles individually sprayed each seal from a distance of 3" in both a static mode and while the shaft rotated at various speeds up to 3525 rpm. The nozzles tried to force water past the seal for nearly two hours.
3. Dust Exclusion Test
The test machine was modified with an enclosed chamber containing a large quantity of fine dust and sand which was vigorously agitated with the chamber attached to the outside of each seal area. The equipment operated at speeds up to 3525 rpm for a period of 70 hours in an environment that was literally a dense dust storm. ProTech was the only seal that passed all three torture tests. After lab testing, it was ready to confirm its performance superiority in field trials.
