Note 1 Under the conditions that contain hard sludge—such as abrasive powders, grinding powders,
and diamond abrasive grains—in the pumping fluid, the service life of the mechanical seal
may become shorter. In such a case, install a filter (e.g. magnet filter or paper filter). Note
that the product cannot be used for water or special liquids such as printing liquids and acidic
liquids. For other special liquids (e.g. pure water, alkaline/acidic liquids, and ceramic liquids),
contact Teral Inc.
Note 2 When the dynamic viscosity of liquids used becomes higher than that in the table below, the
useful life of the motor may become shorter, leading to a burnout. Be sure to use a liquid with
a dynamic viscosity lower than its lime value in the table below. In addition, the dynamic
viscosity of a liquid may drastically increase with decreasing temperature of the liquid. When
using a liquid, confirm the dynamic viscosity of the liquid when its temperature is lowest.
The characteristics of the pump deteriorate as an increase in the dynamic viscosity of the
liquid used.

Note 3 Limit the fluctuations of the power voltage within ±10% of the rated voltage, and also limit the
fluctuations of the frequency within -5% to +3% of the rated value. Avoid continuous
operation if the voltage is not within the range of ±5% of the rated value or if the frequency is
not within the range of ±2% of the rated value.
