Drainage pumps

Applications

River drainage pumps, rainwater drainage pumps for sewerage, small-scale drainage pumps for sewerage, flood control and drainage pumps for agriculture, etc.

Product Lineup

Large scale concrete casing pump

This pump is used when a large amount of drainage is required. It incorporates a structure appropriate for civil engineering.

Drainage pumps for Metropolitan Area Outer Underground Discharge Channel and Showa Drainage Pump Station
With a total drainage capacity of 200 m3/s, it is one of the largest drainage pump facilities in the world. It uses the most advanced technology to reduce construction costs and improve reliability.

Vertical-shaft adjustable vane pump

This pump is used for rainwater drainage and river drainage.

The vane mounting angle can be flexible to adjust the drainage capacity.

Vertical-shaft axial/mixed flow pumps

These pumps can be used for various purposes such as river drainage, rainwater drainage, irrigation, water supply, and sewage.

Axial flow pump: Can be used mainly for a total pump head of 5 m or less.
Mixed flow pump: Can be used mainly for a total pump head exceeding 5 m.

Vertical-shaft volute mixed flow pump

This pump is used for sewage and rainwater drainage, etc.

Horizontal-shaft axial/mixed flow pumps

These pumps are used for flood control and river drainage, etc.

Axial flow pump: Can be used mainly for a total pump head of 3 m or less.
Mixed flow pump: Can be used mainly for a total pump head exceeding 3 m.

Volute/column submersible motor pumps

Volute type: These pumps are used for rainwater drainage and sewage, etc.
Column type: These pumps are used for rainwater drainage and irrigation, etc.

Pump gates

These are pumps built into gate doors. They are small-scale drainage pump facilities installed in small rivers and waterways.

Fluid coupling/fluid coupling built-in speed reducers

These are power transmission devices used for large capacity pump equipment.
They are categorized into:
the charge and discharge type used for clutch functions and the variable-speed type used for rotational speed control. The fluid coupling built-in speed reducer is also available.

Manhole pump system

This system incorporates a submersible pump inside a manhole and integrates monitoring and control equipment, etc. Construction costs can be reduced, since they allow pipelines to be buried at a shallower depth.
