•
Make sure that the room is sufficiently
ventilated, for convection of the heat generated
by the pump and drive. Keep some distance
between the ventilation cover of the electric
motor and wall to enable cooling.
5.3.3 Pipework
When determining and connecting suction and
discharge lines consider the following points:
•
The bore size of the suction line must be larger
than the bore size of the pump hose. The bore
size of the discharge line must be minimal or
larger than the bore size of the pump hose. For
more
information consult your Bredel
representative.
•
Avoid sharp bends and make the radiuses of
the bends are as large as possible. It is
recommended to use Y-connections instead of
T-connections.
•
It is recommended to use a minimum of three
quarter (3/4) of the hose length as flexible hose
in the suction or discharge line. This way
connection lines do not have to be removed
when changing a pump hose.
•
Keep the delivery and suction lines as short and
direct as possible.
•
Do not exceed the maximum working pressure
of the hose pump, refer to section 11.1.1. If
necessary fit a pressure release valve.
Caution
Consider the maximum permissible
working pressure on the discharge side.
Exceeding the maximum working pressure
can cause to serious damage to the pump.
