The seal kit in a centrifugal pump should be replaced approximately once a year, or when leaking or decrease in efficiency occurs. How often you should replace your seal kit depends on the application and the frequency you use your pump. The DG seal kit includes a ceramic seat that protects the backplate from wear and tear.

EDPM (High Temperature) kits are resistant to most products in the food industry, including ozone and radiation. Rated for temperatures from minus 40°F to 302°F. They are not resistant to organic and non-organic fats and oils.
Viton® is particularly well suited for hot fatty oil products. 0°F to 400°F under continuous duty and will take 600°F for short periods of time. Rated at -2° F to 450° F (short term to 600° F).
