TechnologyOil Lifter

The Oil Lifter is a lubrication system for the mechanical seal (shaft sealing device), which serves as the heart of a submersible pump.
It is a standard feature that supports the durability and reliability of Tsurumi submersible pumps.

Mechanical Seal
(Shaft Sealing Device)

The mechanical seal, which can be considered the heart of a submersible pump, is mounted on the main shaft. An oil film forms on the seal faces, helping prevent water from entering the motor.

Even when the oil level drops, oil rises along the guide vane to lubricate and cool the upper seal face of the mechanical seal, helping maintain stable sealing performance. This extends mechanical seal service life, improves the quality and reliability of submersible pumps, and reduces maintenance costs.
