10 Installation, Piping and Wiring
CAUTION!
When any abnormality or irregularity is noticed, stop the
pump immediately and restart it from the first step.
[Flooded suction method]
(3)
Use M5 machine screws
for fitting the pump. If the
floor on which the pump is
installed is resonant and caus-
es a loud noise, fix the pump
with rubber mountings
(4) Preparation of hoses
Cut the ends of hoses flat
before starting pump installa-
tion.
(5)
Do not install the pump verti-
cally.
This cause damage of pump.
(Side view of hose)
In case there is liquid inside the suction
piping.
In case there is no liquid in the suction
piping.
(This is not allowed for the B type.)
[Priming method]
(In case the pump chamber is wet)
10-1. Installation
(1)
Choose a place where ambient temperature will not exceed 40
º
C
and ambient humidity of 90%RH. Allow sufficient space around
the pump for easy access and maintenance. Do not install the
pump out of outdoors.
(2)
Install the pump in a position lower than the surface of the liquid
in the tank on the suction side, to prevent dry running (flooded
suction method).
If it is necessary to install an
R
type pump in a position in
which the inlet of the pump remains higher than the liquid
surface (a suction lift), refer to the illustrations on the
right. In this position, the pump does not suck unless the
pump chamber is wet. (The MDG-R2B type pumps do
not function on a suction lift.)
