5.3.3 Pipework
When determining and connecting suction and
discharge lines consider the following points:
•
The bore size of the suction and discharge lines
must be larger than the bore size of the pump
hose. For more information consult your Bredel
representative.
•
Limit the presence of sharp bends in the
discharge line. Make sure that the radius of the
bent discharge line is as large as possible
(preferably 5S). It is recommended to use Y-
connections instead of T-connections.
•
It is recommended to use a minimum of three
quarters (3/4) of the hose length as flexible
hose in the suction or discharge line. This
avoids the need to remove the connection lines
when changing a pump hose.
•
Keep the delivery and suction lines as short and
direct as possible.
•
Select the correct mounting material for flexible
hoses and make sure that the installation is
suited for the design pressure of the system.
•
Prevent any possibilities of exceeding the
maximum working pressure of the hose pump.
Refer to §
11.1.1 . If necessary fit a pressure
relief valve.
•
Make sure that the maximum forces on the
flanges are not exceeded. The permissible
loads are given in the following table.
CAUTION
Consider the maximum permissible work-
ing pressure on the discharge side.
Exceeding the maximum working pressure
may lead to serious damage to the pump.
