Note 1 Note that the product cannot be used for water or special liquids such as printing liquids or acidic
liquids.
Note 2 If you pump liquids with a dynamic viscosity beyond the limit specified in the following table, the
service life of the motor may become shorter and the motor may burn out. Be sure to use a liquid
with a dynamic viscosity below the limit specified in the following table. Note that a decrease in
liquid temperature could significantly increase its dynamic viscosity. Before pumping a liquid,
check its dynamic viscosity at the minimum liquid temperature. The characteristics of the pump
deteriorate as an increase in the dynamic viscosity of the liquid.

Note 3 If the bore size is different from the standard size, the maximum suction pipe length is inversely
proportional to the square of the bore size.
Note 4 Limit the fluctuations of the power voltage within ±10% of the rated voltage, and also limit the
fluctuations of the frequency between –5% and +3% of the rated value. Avoid continuous
operation if the voltage is not within ±5% of the rated value or if the frequency is not within ±2% of
the rated value.
