3.5 Water Piping
Connect piping 9.52 mm in diameter or more to the Coolant inlet / outlet using care not to mistake the
ports (Refer to Fig. 3
～
6.)
The water included little impurities (ex. Industrial Water) is recommended for
cooling water.
Depending on the water quality, the inside wall of cooling water tube is covered
with water scale (CaCO
3
etc.) and cooling water flow rate may be decreased.
Cooling water tube is corroded by Chlorine ion (Cl
-
) and cooling water leak may
be caused. In case of using pure water, cooling water leak may be caused by
metal component dissolution, too.
In these cases, the repair service may be for a fee.

(1) Be sure to flow the Coolant with the volume indicated on
“
Table. 3
Performance specifications” or more. The pump temperature would rise
up if the water volume becomes less than specified particularly on high
suction pressure operation and cause the pump failure.
(2) You are recommended to put a Flow meter for the Coolant and cause the
interlock so that the Pump stops if the coolant flows less than specified
volume.
(3) When the operation stopped in winter, the water piping and the pump have
a risk of breaking by freeze-up of the water inside. Open the Coolant outlet
during operation stop and storage to discharge the water inside by blowing
in the pneumatic air through the water inlet.
