Frequently Asked Questions
This washer creates the correct spacing between mounting or internal components, helping maintain alignment and reducing uneven wear or leaks.
Replace it during pump overhauls or whenever you disassemble the internal components; if there’s any sign of deformation or wear, a new washer restores proper spacing and alignment.
Yes — the OEM washer is manufactured to exact tolerances and materials. Using a non‑spec washer may compromise component spacing, alignment or cause premature wear.
By maintaining precise spacing and alignment, the washer reduces internal stress, helps avoid misalignment‑related wear or leaks, and thus contributes to a longer operational lifespan for the pump assembly.
