Lip and labyrinth seals provide protection in harsh oil and gas applications.
Bearings
Bearings are small parts of pump systems that play a critical role. They bear the load of the pump, allowing rotation. They must be properly lubricated and temperatures monitored to prevent failure. These articles explain the causes of bearing failure and how to prevent them - thus protecting overall system life.
Outside lubrication experts help improve protocols and minimize downtime.
Safely immerse motor compressors in process gas without risking costly damage.
The best option for preventing bearing currents depends on the source of the problem.
Properly aligned bearings can be critical to the life and health of pumps.
Appropriate bearing selection and best-practice maintenance procedures can make a difference in pump reliability, service life and production.

A northeast Germany refinery increased its MTBF by upgrading eight pumps.
This equipment eliminated a SAG copper mill gearbox’s maintenance issues resulting from contact lip seals that had a short and unreliable service life.
Use a mathematical model that estimates vibration at the top bearing of a motor used on a vertical, wet-pit, column type pump.
Mapping and testing ensure proper fit and function of replacement parts.
To optimize the lubrication of a bearing, proper oil viscosity selection is essential.
