운반·설치상의 주의사항
INSTALLATION
- The pump should be installed indoors. In case of installing outdoors, set eaves to avoid exposure to wind
and rain, and prevent the pump from freezing.
- The pump should be in pressurized condition. (Recommended suction pressure: 0.2kgf/cm 2 )
To prevent dry running, the water tank should always be higher than the suction port of
the pump. Keep the minimum suction pressure at all times.
Vent air out from the suction side tank after cleaning it.
Even in a pressurized condition, running the pump with air in the tank or with suction
condition, the mechanical seal may be worn and consequently the rotational part may fall
down upon the stationary part.
-Piping direction can vary depending on circumstances.
-Piping direction can be adjusted by loosening the union on discharge side.
-Tank is separately packed in shipping.
- Even in a pressurized condition, if an elbow is used, the suction piping should never be
of smaller diameter than the pump suction.
- An elbow close to the pump suction flange should be avoided. Abnormal noise and vibration may occur.
- The piping should be adequately supported on both sides to reduce mechanical stress on the pump
- Make the piping run as short as possible and minimize the number of elbows
- Attach a strainer for filtering foreign objects to the end of the suction piping.
- Install a stop valve on the suction side and the discharge side of the pump to make pump maintenance
easier.
- Install the bypass on the discharge side to make pump maintenance easier.
- When the pressure tank is damaged, the discharge pressure can fluctuate or the piping can leak.
- To minimize noise of the pump, install a flexible joint on the suction piping and the discharge piping, and use
an anti-vibration rubber.
