Caution:
- Fluid has basic lubricating and compatible chemicalcharacteristic, and it exclude solid impurity substance.
- Avoid idling
- The pump can only be operated in appointed direction,or else seal of the shaft will be wrecked.
- To avoid excessive pressure, the sysrem or pumpshould be equipped with a relief valve.
- Relief valve equipped with the pump functions as anatmospheric valve in a short time, other than a overflow valve.
- An additional overflow valve should be installed ifoverflowing exists in a long time.
