Protect Pump Bearings with the Orion BPD

Orion Engineered Seals - Bearing Protection Device (BPD)The Orion Engineered Seals patented Bearing Protection Device (BPD) represents state of the art bearing protection technology and is the premier non-contacting bearing protection device offered. The BPD was designed with an understanding of the nature of the bearing housing environment under all operating conditions and utilizes the laws of physics to create what has proven to be the best performing and most cost effective way to protect the bearings of your rotating equipment.

2 Common Pump Problems, 1 Solution… the BPD

Bearing Protection Device (BPD) - Centrifugal PumpProblem 1: Pumps routinely operate in high humidity and dirty environments. They are also commonly operating batch processes meaning the pump is cycled on and off.   These operating conditions results in contamination ingress into the bearing housing, which is the primary cause of shortened bearing life.

Solution: The BPD – Designed for the conditions encountered by centrifugal pumps


Problem 2: To combat the high operating temperatures and environmental conditions, oil mist lubrication is widely used by refineries. Oil mist lubrication’s main drawback is containing the stray mist exiting through the bearing housing shaft ends, which can create environmental, health, and safety issues.

Solution: The BPD – Designed to contain oil mist lubrication

  • Redundant dynamic and static contamination ingress protection independent of speed.
  • No speed limitations, i.e., can be slow rolled indefinitely without damaging the seal.
  • Operates effectively up to 650F in heavy steam environments.
  • Split and solid designs perform identically
  • Retains lubrication regardless of method
  • Will not allow automatic oilers to overfill the bearing housing
