Pump Bearing Protection
Maximize Pump Life
The Importance of Bearing Protection
Pumps are vital to the industrial process and designed to operate for many years, yet they consistently come out of service due to product leakage from mechanical seal failure. Mechanical seals can fail as a result of axial movement and shaft deflection caused by bearing damage.
Protect against bearing damage to significantly increase pump reliability.
The High Cost of Contact Seals
Contact seals, such as lip seals, are commonly used on pumps to seal the bearing housing. Yet, due to their contacting nature, they wear at the point of contact or groove the shaft, rendering them ineffective in a short period of time. This allows lubrication to escape and contamination to enter the bearing housing.
The resulting bearing damage causes axial movement and shaft deflection, which in turns causes the mechanical seal to fail. The end result is catastrophic equipment failure.
A Permanent Sealing Solution
Invented in 1977, the Inpro/Seal Bearing Isolator has been increasing pump reliability through permanent bearing protection for over 40 years. The Inpro/Seal Bearing Isolator is a non-contacting compound labyrinth seal designed with proven, innovative features to permanently protect against contamination ingress and lubrication loss.
Designed to last the lifetime of your pump, Inpro/Seal Bearing Isolators significantly increase mean time between repair (MTBR) and decrease maintenance costs.
Bearing Isolator Designs for Pumps
