Safety instructions
Live parts
· The device must be disconnected from the power supply before it
is opened
· Isolate damaged faulty or manipulated devices from the mains in
order to de-energise.
Emergency stop switch
An emergency stop switch is to be connected for the entire plant.
This should enable the entire plant to be shut down in the event of
an emergency in such a way that the overall plant can be brought
into a safe condition.
Unauthorized access
Ensure that there can be no unauthorized access to the unit.
Hazardous media/contamination of persons and equipment
· Ensure that the pump hoses are resistant against the media being
conveyed
· Always observe the safety data sheets for the media to be
conveyed. The system operator must ensure that these safety data
sheets are available and that they are kept up-to-date.
· The safety data sheets for the media being conveyed are always
decisive for initiating countermeasures in the event of leakage to the
media being conveyed.
· Observe the general restrictions in relation to viscosity limits,
chemical resistance and density.
· Always switch the pump off before exchanging the pump hose
· In case of corrosive liquids or high temperature liquids, is
necessary to control the leakage using hose leakage sensor or other
external devices.
Correct and proper use
· The unit is not intended to convey or regulate gases or solid media
· Do not exceed the rated pressure, speed or temperature for the
pump
· The unit may only be used in accordance with the technical data
and specifications provided in these operating instructions and in
the operating instructions for the individual components
· The system is not designed for use in areas of risk from explosion
· Only switch the pump on if it has been properly fastened to the
floor
· Only switch the pump on if it the front cover has been attached.

MANUAL PERIBEST I12 –I17 –I21

· Do not carry out any maintenance operations or dismantle the
pump without first making sure that the pipes are not under
pressure and are empty or isolated.
· As the peristaltic pump is volumetric and its functioning is positive
displacement, it is necessary to prevent a possible overload of
pressure, due to for example, the accidental closure of a valve. For
this reason it is advisable to fit a safety device such as: a safety valve,
pressure limiter, etc.
Operational lifetime of the pump hoses
The operational lifetime of the pump hoses cannot be precisely
specified. For this reason, the possibility of fracture and
consequential leakage of liquids must be accounted for. If the hose
leakage sensor (optional) is fitted, then the pump can be stopped
and / or an electrical valve can be actuated.
In addition, as the hose has an indeterminate life and due to the
possibility of its breakage or deterioration, the user is responsible
for the prevention of a possible (although most unlikely)
incorporation of particles form the hose into the product being
pumped. This can be achieved e.g. by means of filtration, a hose
rupture alarm or other means suitable for the respective process
CIP cleaning
In the event of CIP cleaning, it is necessary to obtain information
from the manufacturer about correct installation of the pump as well
as regarding the compatibility of the cleaning agents with the pump
hoses and the hydraulic connections.
Cleaning should be undertaken at the recommended maximum
temperature.
Direction of rotation/flow direction
The pump's direction of rotation in relation to the desired flow
direction must be checked prior to every start.
Disconnect the pump from the mains
You may only carry out work on the pump after it has previously
been switched off and disconnected from the mains.
Environmental influences
· The device is not suitable for outdoor operation
· Take suitable measures to protect the device from environmental
influences such as UV rays, moisture, frost, etc.

The pump hose liner material should be chemically resistant with the product to be pumped.
Dependent on the specific requirements of your application a corresponding pump hose must be
selected. For each pump model various hose types are available. The material of the inner liner of
the pump hose determines the hose type. Each hose type is marked by a unique colour code.

The PeriBest pump hoses have been carefully machined, therefore there are minimum tolerances in
wall thickness. It is very important to guarantee the correct compression of the pump hose, because:
-When the compression is too high, it creates a too high load of the pump and pump hose,
which may result in a reduction of the life of the pump hose and bearings.
-When the compression is too low, this will result in loss of yield and backflow. Backflow
results in a reduction of the life of the pump hose.
In order to achieve optimal life of the pump
hose, the compression force of the pump
hose can be adjusted by placing several
shims under the pressing rollers.
The shims are fitted between the rotor and
the pressing roller.
The number of shims will vary for each
counterpressure situation.

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.
