Order Received for Immersible Motor Vertical Mixed-flow Pumps for Imado Drainage Pumping Station [Orders Received in August 2025]

The southeastern part of Takatsuki City, Osaka, has long suffered from flooding due to its low-lying terrain along the Yodo River, the biggest river in Osaka. The Imado Drainage Pumping Station was built to protect the safety of this area. For approximately half a century, the station and its two original horizontal mixed-flow pumps have successfully helped reduce local flooding.

Today, however, the equipment is over 50 years old and faces serious aging problems. Additionally, increasingly severe heavy rains caused by climate change require more reliable drainage functions. To meet these needs, Torishima proposed our immersible motor pump technology, which was selected for this project. The key feature of this technology is that the watertight design allows the integrated pump and motor to continue operating even if the station is flooded. This ensures that drainage functions remain active during emergencies and supports a faster recovery.

We are now moving forward with the manufacture, design, and construction planning for the project, aiming for completion in May 2027. This renewal will enhance the overall reliability of the pumping station and continue to protect the safe and secure lives of local residents well into the future.
