Installation
Unpacking and Inspection
When unpacking carefully follow the instructions as given on the packaging or on the hose pump.
Check that your delivery is correct and check it for any transport damage. Report any damage
immediately to your PeriBest representative.
Conditions of use
Make sure that the hose pump is in an area where the ambient temperature during operation is not
lower than -20 °C and not higher than +45 °C.
Set-up
The pump materials and protective layers are suitable for indoor set-up and a protected outdoor
set-up. Under certain conditions the pump is suitable for limited outdoor set-up or a salty or
aggressive atmosphere. Consult your PeriBest representative for more information.
Make sure that the floor surface is horizontal and has a maximum slope of 5 mm per metre.
Make sure that there is sufficient room around the pump to carry out the necessary maintenance
activities.
Make sure that the room is sufficiently ventilated, so that the heat developed by the pump and drive
can be discharged. Keep some distance between the ventilation cover of the electric motor and wall
to enable the supply of necessary cooling air.
Piping
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 PeriBest 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. It is recommended to use Y-connections instead of T-
connections.
-
It is recommended to use flexible hose in the suction or discharge line.
-
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.
