Oil
This Oil Lifter was developed to improve quality and reliability of our submersible pump by enhancing sealing performance of the mechanical seal.
* The Oil Lifter is a lubrication device for the mechanical seal that is the heart of the submersible pump.* The Oil Lifter stabilizes and enhances mechanical seal lubrication and cooling effect. * Offers stable sealing performances even if the oil level drops. Facilitates periodic inspection.
Guide vaneOil suction port
This design features an independent pump casing built separately from the oil casing which incorporates the mechanical seal. An intermediate chamber, opened to the outside, is installed between the pump casing and the oil casing.
Thanks to this configuration, the mechanical seal is exposed to the static (submergence) pressure only without the pumping pressure operating on it. This prevents the mechanical seal from premature wear under the high-head pumping condition.

Specification Table
The entirely cylindrical drive channel maintains the motor cooling efficiency adequately high even during operations at a low water level. Also, with the discharge port on its top (sketch), the pump can be installed in a narrow place.
Enables the pump to be lifted up/down without disconnecting it from piping and stably installed true to the center of gravity.
The dual impeller (photo) remarkably increases the power of pumping up water from a great depth.
Part of pumped fluid flows in between the outer cover and the motor housing before discharge and thus cools the motor on its way. This allows the pump to operate long and continuously even if it is exposed to the air.
