5 INSTALLATION
5.1 Unpacking
When unpacking carefully follow the instructions as given on the packaging or on the hose
pump.
5.2 Inspections
Check that your delivery is correct and check it for any transport damage, see “Description:
“Identification of the product”, § 4.1. Report any damage immediately to your Bredel
representative.
5.3 Installation conditions
5.3.1 Ambient conditions
Make sure that the hose pump is in an area where the ambient temperature during operation
is not lower than –20° and not higher than +45°C.
5.3.2 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 Bredel
representative for more information.
• Make sure that the floor surface is horizontal and has a maximum slope of 1 mm per
meter.
• 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.
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.
• Limit the presence of sharp bends. Make sure that the radius of the bends are 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 quarter (3/4) of the hose length as
flexible hose in the suction or discharge line. In this way you prevent that connection
lines must be removed when changing a pump hose.
• Keep the delivery and suction lines as short and direct as possible.
• Prevent any possibilities of exceeding the maximum working pressure of the hose
pump, see “Specifications”: “Performance”, § 10.1.1. If necessary fit an overpressure
valve.
