3.3 Precautions for installation
Warning
Before rotating the pump shaft by hand to check it, be sure to turn off the
main power. An unexpected start 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 pumping liquid may be splashed on the motor section.
Warning
Do not install the product in a hot or humid place.
Otherwise, it may lead to heating, ignition or electric leak.
(2) Install the product so that the motor can take air in.
(3) Securely install the product on a flat place without any wobbles.
(4) Select a convenient place to conduct maintenance and inspection.
Secure space for maintenance.
(5) The mounting surface must be strong enough to prevent the
amplification of vibrations while the pump is running. (Restrict the
total amplitudes in X, Y, and Z directions (see the right figure) to 33μm
at 50 Hz and to 29μm at 60 Hz during the operation of the pump.)
(6) It is necessary to make a mounting hole larger than the outside
diameter of the pump section so that the pump section can fit into
the tank (oil tank). See the dimensional outline drawing.
(7) Install the pump 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 10 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 cutting
powder, dirt, or other materials are predicted to accumulate on the
bottom of the tank, ensure as large a distance as possible from the
bottom at the design stage.
Note
Always keep the liquid level in the tank (oil tank) above the Minimum
liquid level. Keep the suction port of the pump at least 10 mm away
from the bottom of the tank (oil tank).
(9) The product is coated. If you need to overcoat it in a different color for a compelling reason, lightly
roughen the product surface with sand paper or the like and then coat it, which improves the
adhesion properties of the coating film. (Be sure to check the overcoatability of the paint.)
(10) Install the product at a place where a secondary hazard does not occur in the event of any liquid
leak.
(11) If the system could be exposed to the freezing temperature in winter, be sure to apply antifreeze
measures such as heat insulation and heater installation to the pump, valves, piping, etc.
(12) Securely install the pump.
