DiamondFace coated shaft seals for extended service life

An HJ4S1 mechanical seal was applied in a pump from Bornemann Pumps as part of the “Deer Creek” project in Canada. The extremely hard diamond coating of the seal faces (DiamondFaces) extended the service life of the seal thirty times beyond that which would have otherwise been possible.
