Liquid piping
(1) There is the distinction of suction and discharge
side tubes of dampener. Pay attention to the con-
nection. "I" is marked for suction side and "O"
for discharge side.
(2) Keep the pump and the dampener free of any
excessive load such as piping weight when tub-
ing each devise. Support tubing to protect the
dampener from tubing vibration.
(3) In case that high temperature liquid is handled,
piping must be done so that the dampener can
not be affected by the expansion and shrinkage
of the pipe because of the heat.
(4) Install the filter in the discharge piping.
(5) Employ the tube which has the pressure resist-
ance more than that of specified max. pressure of
the dampener.
(6) For mounting of pipe joints, pay attention so
that the air can not be sucked in. Especially, the
air sucked in suction piping causes unstable or
impossible discharge.
(7) PFA tubes are equipped for suction and dis-
charge ports. Tube diameters are:
PDA-20W : 19 × 16 mm
PDA-40W : 25 × 22 mm
PDA-80W : 25 × 22 mm
Use the tube fittings which correspond to tube
diameters(See the left draw.).
Note. Pipe line tubes should have larger bore
than the suction/discharge bore.
