Application

The double (two) stage structure achieves a higher head than other series that are with the same motor output.
The cylindrical body in protrusions in small diameter is the most suitable pump for drainage in a narrow pit such as deep well drainage.
The motor is effectively cooled down for the discharge and cylindrical water channel.
The back pressure releasing mechanism is adopted to enable a long service life of the mechanical seal.(EXCEPT U-282AW)
Infiltrative Water Detector is incorporated as a motor protector(EXCEPT U-232AW, 282AW, 2153AW), ensuring a reliable design that prevents motor burnout.
The impeller is made of high chromium cast iron (with 25% chromium) known for its wear resistance.
The design of the pumps is considered for inspection and easy maintenance.
