3. Operating conditions
1. Permissible pressure
Pump permissible pressure is 1.0MPa. Do not allow the pump discharge pressure to exceed the limit.
2. Slurry liquid
Slurry liquid can not be used except for the KK type of SiC bearing. The KK type can handle slurry in the fol-
lowing conditions:
• Slurry concentration up to 5 wt%
• Slurry hardness up to 80 Hs
• Slurry size up to 50
μ
m
Contact us for detail before slurry transfer.
NOTE: Not only friction parts but also plastic parts are worn when handling slurry liquid.
Note that periodic pump change is needed.
3. Performance change along with specific gravity and viscosity
Shaft power, discharge capacity and discharge head vary with specific gravity and viscosity. The pump has
been made in accordance with the specified operating condition at order phase. If the operating condition
has been changed since then, contact us before use of the pump.
4. Influence by liquid temperature
Viscosity, vapour pressure and corrosiveness vary with the temperature change. Pay attention to the change
of liquid characteristics.
