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.
