10-2. Piping
Piping instructions
(1) To minimize the friction resistance, the shortest piping possible
with the minimum number of bends should be utilized. Especially
for suction piping, employ as larger and shorter hose as possible.
(2)
Use a corrosion-resistant vinyl hose that can endure the pressure
made by the pump operation.
If the connection on the suction side is inadequate, air may be
mixed in.
(3) Hose size
Select a hose in accordance with the diameter of the pump port.
A reliable connection is not guaranteed if different size of hose is
used.
As the hose on the suction side, in particular, tends to be crushed
under the sucking force, the use of a braided hose is recommend-
ed. (In the case of hot liquid feeding, special attention must be
paid in the selection of a hose.)
(4) Valve installation
Install valves close to the suc-
tion and discharge port.
· Suction side valve:
For easy removal or mainte-
nance of the pump.
· Discharge side valve:
For adjustment of the dis-
charge rate or head.
(5) Hose connection
Press the hose end firmly
against the discharge or suc-
tion port until it reaches the
bottom of the port.
*Use a fastener (such as a
hose band) to make the con-
nection firm and free of liq-
uid leakage.
Caution
Do not tighten the connec-
tion ports (suction and dis-
charge) excessively as they
are made of plastic resin
and are easily damaged.
