1.Consult POOCCA when pump is used over rated pressure because there is a restriction on operating condition.
2.The maximum shaft speeds shown in the above table are at suction pressure 0 kPa (0 PSIG).
3.The table above shows specifications for using petroleum based oils.
Pumps (customized design) for special fluids are also available. Their operating pressure and maximum shaft speed however differ from the values in the table above depending on the fluid type.
Range of operating temperature and viscosities may differ from those of petroleum based oils due to their characteristics.
