The pumproom at Hakozaki Pump Station.

Ebara has recently delivered three easy-maintenance/inspection vertical shaft mixed flow pumps to the Hakozaki Pump Station in Fukuoka, Japan.

The Hakozaki Pump Station was completed earlier this year to mitigate flood damage in the Hakozaki district.

The pumps have new configurations with the submerged bearings positioned on the lower part of the impeller. During maintenance, this eliminates work to pull up the pump for inspection and to disassemble the pump for bearing replacement. With heavy equipment such as a crane no longer required, maintenance times are shortened and costs reduced.
