Note:
Since dimensions are based on JIS 10K standard, they may be changed according
to standards/specifications.
Outer dimensions refer only to electric motors at maximum motor output,
therefore there may be differences in outer dimensions. For details on
related dimensional outline drawings, please contact us.
Installation and piping: Please install an inverse U-bent pipe as suction
piping for efficient self-priming. For details, please refer to the page
for UHN type.
Sealing: When equipped with a mechanical seal, supply of sealing water
from the outside may be necessary for suction pumping. Gland packing may
not be used for force pumping when the pressure is extremely high.
