Caution
Do not run the pump at a frequency exceeding 60 Hz. Failure to observe
this may overload the motor, causing it to burn out.
3.3 Precautions for installation
Warning
Before rotating the main shaft by hand to check it, be sure to turn off the
main power. Sudden operation of the pump may cause an accident.
(1) Install the product in a well-ventilated place with minimum exposure to dust and moisture. (Refer
to the Installation location in 2.3. Standard specifications [page 2-2]). In particular, avoid
installing the product in a place where the liquid used is splashed on the motor section.
Warning
Do not install the product in a place exposed to high temperature and
moisture.
Failure to observe this may cause heating, ignition and electric leakage.
(2) Install the product in such a way that the motor can take in air.
(3) Select a flat place for the mounting surface and then install the product
so as not to rattle.
(4) Select a place convenient for maintenance and inspection. Ensure
maintenance clearances.
(5) The mounting surface should be strong enough to prevent vibration
from being amplified when the pump is running.
(Restrict the total amplitudes in X, Y and Z directions (see the right
figure) to 33
μ
m at 50 Hz and 29
μ
m at 60 Hz during pump operation.)
(6) It is necessary to make a mounting hole larger than the outside
diameter of the pump section so as to put the pump section into the
tank (oil tank). See the dimensional outline drawing.
(7) Install the product so that the main shaft becomes vertical.
(8) Use the product with the pump section immersed under the oil level.
The suction port should be at least 5 mm away from the bottom surface
of the tank (oil tank) to prevent the strainer from getting clogged with
cutting powder, dirt, or other materials. If it is predicted that cutting
powder, dirt, or other materials accumulate on the bottom of the tank,
ensure as large a distance as possible at the design stage.
Note
The liquid level in the tank (oil tank) should always be above the minimum
liquid level.
Keep the suction port of the pump at least 5 mm away from the bottom of
(oil tank).
(9) The product is coated, but if it is overcoated to another color for unavoidable reasons, lightly
roughen the product surface with sand paper and then coat it. The adhesion properties of the
coating film are improved. (Be sure to check that a paint to be used is applicable to overcoating.)
(10) When the liquid leaks from the product, install it in a place where it is not subjected to secondary
damage.
