Specific Product Precautions 2
Be sure to read this before handling the products. Refer to the back cover for safety
instructions and the "Operation Manual" for handling the products. Please download

Caution
1. Do not apply pressure to the pump. If the pump op-
erates with pressure applied, the repeatability may
decrease or liquid may leak to the OUT side when
the pump is off. Tank liquid level must be lower than
the pump and the OUT side tube end must be high-
er than the tank liquid level. Remove any air bub-
bles in the piping and pump chamber.
Tank
2. Make sure to remove any air bubbles in the piping
and pump chamber before use.
3. Preparation before piping
Before piping is connected, it should be thoroughly blown out
with air (flushing) or washed to remove chips, cutting oil and
other debris from inside the pipe.
4. Always tighten threads with the proper tightening
torque.
When piping the fitting to the body ported (threaded ports), the
installation method and tightening torque value may vary de-
pending on the seal structure (shape) or material of the fitting
to be used. Check the methods and precautions recommend-
ed by the fitting manufacturer to be used, and be sure to check
for leakage. It is customer's responsibility to verify the compat-
ibility of the fitting and operating liquid.
The table below indicates the reference value when KQ2 series
is used for water.

When mounting the pump, tighten it with the proper tightening
torque shown below. For base mounted, tighten the screw
surely to the correct torque in the table below after confirming
that the O-ring is mounted on the interface properly.

5. Mount the pump on the flat surface.
Applicable model: All models
6. Remove dust from the pump mounting surface
completely.
The surface roughness of the mounting surface should be
Rz3.2 or less.
Applicable model: Base mounted
7. When connecting tubing to the tube connection type,
please make sure inserting it straight to the end of
the tube inlet.
If external force of 10 N or more is applied to tube
inlet, the inlet may become damaged, and leakage
or breakage could occur.
Select appropriate tubing while referring to the table
below.

The holding force varies by the tubing material. Be
sure to confirm the holding force of each material
before operation. After connecting the tubing, please
do not apply load such as tensile force, compression,
or bending force.
8. When the tubing is long or according to the operating
conditions, tubing may thrash about, causing damage
to the tube inlet of the pump, or the tubing to come
off or deteriorate. In this case, secure the tubing to
prevent its uncontrolled movement.
9. If the removed tubing is to be used again, cut off the
section of the tubing which has been gripped by the
fitting.
