Oil Lifter

The oil lifter was invented by Tsurumi.

It improves longevity and durability by maintaining proper lubrication of the top seal faces for an extended period of time.

Utilising the centrifugal force of the shaft seal, it forcibly supplies lubricating oil to the mechanical seal and continues to supply the oil to the upper seal faces even if the lubricant falls below the rated volume.

This very simple device in a Tsurumi pump will not only reliably lubricate and cool down the seal, it also maintains a stable shaft seal and doubles the time interval between inspections, oil changes and planned seal replacement.
