3.3 Precautions for installation
[VKN-e/VKP-e]
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) 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 33
μ
m at 50 Hz and to 29
μ
m
at 60 Hz during the operation of the pump.)
(5) Select a convenient place to conduct maintenance
and inspection. Secure space for maintenance.
(6) 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.)
(7) Do not install the product in a place where a secondary hazard could occur in the event of any
liquid leak.
(8) 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.
(9) Securely install the pump.
Recommended size of pump mounting bolt: M10
The pump is provided with four mounting bolt-holes, but they are intended to extend the range of
use. You can install the pump using only two diagonally-located mounting holes without any
problems.
Note
Securely fix the pump in place with the bolts. Otherwise, it may lead to
abnormal vibration or other problems.
(10) Do not hoist the equipment with the pump attached. Otherwise, it may damage the hoisting
equipment/devices and the pump may fall.
(11) When you hoist or move the pump, be sure to handle the pump carefully so that the pump section
would not be subjected to an impact or imbalanced load. The container may greatly tilt depending
on its center of gravity.
