The addition of a Viton O ring placed above the LDPE seals on the plunger can improve the performance of the Ezi-action® Drumpump when back pressure increases and when very strong acids are dispensed.
Viton has a good resistance to 83% nitric acid and chemical formulations using high concentrations of hydrogen peroxide.
Viton also has excellent memory and could be a better option than LDPE seals alone when crystals form.
