Storage
If the equipment is to be stored prior to installation, place it in a clean location. The pump
should be stored in an ambient temperature of 15°C (59°F) to 25°C (77°F) and relative humidity
below 65%. It should not be exposed to any heat source e.g. radiator, sun as this could result
in a negative way on the tightness of the pump. Do not remove the protective covers from the
suction, discharge and air connections which have been fastened to keep pump internals free
of debris. Clean the pump thoroughly before installation.
1.4.
Foundation
The support of the pump is furnished with mounting holes. Fix the pump on a stable
foundation, which is able to absorb vibrations. It is essential for the operation of the pump to
mount the pump with the feet in a downward direction (see sketch in chapter 1.8 “Example of
installation”).
1.5.
Suction and discharge piping
Suction and discharge piping should be fully supported and anchored near to but independent
of the pump. The piping to the pump should be a hose, to prevent undue stress and strain on
the pump connections and the piping.
1.5.1.
Connection of suction pipe
Remember that the suction pipe/connection is the most critical point, especially if the pump
is priming. Just a small leakage will dramatically reduce the suction capability of the pump.
When connecting the suction pipe, following is recommended.
1)
For satisfactory operation, use reinforced hose (the suction power may otherwise
shrink the hose) or other flexible piping. The internal diameter of the hose should be
the same as on the suction connection (at the bottom of the pump) to have best
suction capability.
2)
Make sure that the connection hose - pump is completely tight, otherwise the suction
capability will be reduced.
3)
Always use as short suction pipe as possible. Avoid air pockets which can arise with
long piping.
1.5.2.
Connection of discharge pipe
For this connection it is only recommended a simple and positive flow connection. Use a hose
or flexible piping (minimum one meter) between the discharge connection and any rigid fixed
piping. Coil the hose at least one turn. All components (hose, pipe, valves etc.) on the discharge
piping must be designed for minimum PN 10.
