A robust mechanical seal is an essential part of any successful slurry pumping formula which is why when we designed the HS pump we made sure we engineered the perfect seal to accompany it.
HS Series seals are individually protected and in tandem configuration. This means each set of springs are protected from the slurry and provides equal and real back up in the event a lower seal is compromised.
Next, we made some industry leading advancements in the seal chamber itself. We incorporated anti-vortex oil veins, which ensure the seal remains clean and lubricated without the internal eddies and vortexes created by oil lifters. Then, we boosted the pressure venting in the seal chamber to allow for greater submergence as well as less internal pressure on the seal itself.
