Reliable Sealing Solution
-
Type 2 bellows seal with standard 200 PSI inlet rating reduces the leak risk and expense of multiple seals per pump.
-
Robust axial thrust control bearing reduces premature seal failure due to elevated inlet pressure, starts, stops, and other difficult application conditions.
