4.3Operation of the pump
The heart of the pump head consists of a specially
constructed pump hose (A) which lies contorted against
the inside of the pump housing (B). Both ends of the
16
hose are c onnected to the suction and discha rge lines
by means of a flange construction (C). A bearingmounted rotor (D) with two facing pressing shoes (E) is
in the centre of the pump head.
In phase 1 the lower pressing shoe compresses the
pump hose by the rotational movement of the rotor,
forcing the fluid through the hose. As soon as the
pressing shoe has passed, the hose recovers to its
original shape due to the mechanical properties of the
material.
In phase 2 the product is drawn into the hose by the
(continuous) turning motion of the rotor.
DESCRIPTION
In phase 3, the second pressing shoe will subsequently
compress the pump hose. Due to the continuous
rotating movement of the rotor not only new product is
sucked in, but also the already present product is
pressed out by the pressing shoe. When the first
pressing shoe runs from the pump hose, the second
pressing shoe has already closed the pump hose and
the product is prevented from flowing back. This
method of liquid displacement is also known as the
"positive displaceme nt principle".
17
DESCRIPTION
4.4Pump hose
4.4.1General
A:Outer extruded layer made of natural rubber
B:Four nylon reinforcement layers
C:Inner extruded liner
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.
Consult your Bredel representative for
more detailed information about the chemical and temperature resistance of pump
hoses.
The Bredel 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 compre ssion 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.
18
•When the compression is too low, this will result
in loss of capacity and backflow. Backflow
results in a reduction of the life of the pump
hose.
4.4.2 Hose compression force adjustment
(shimming)
In order to achieve optimal life of the pump hose, the
compression force of the pump hose can be adjusted by
placing a number of shims under the pressing shoes.
The shims (A) are fitted between the rotor (B) and the
pressing shoe (C). The number of shims will vary for
each counterpressure situation.
The paragrap h 7.9 describes how to sele ct and install
the shims.
4.4.3Lubrication and cooling
The pumphead, in which the rotor and pump hose can
be found, is filled with Bredel Genuine Hose Lubricant.
This lubricant lubricates the movement between the
hose and the pressing shoes and dissipates the
generated heat via the pump housing and the cover.
DESCRIPTION
The lubricant is food grade. See § 10.1.5 for the
required quantity and NSF registration.
Consult your Bredel representative for
lubrication recommendations when operating the hose pump below 2 rpm.
4.5Gearbox
The hose pump types described in this manual use coaxial gearbox units.
The gearboxes are fitted with a foot rest. The outgoing
shaft has been fitted with a spline.
19
DESCRIPTION
4.6Electric motor
If the electric motor has been standard supplied by the
manufacturer, it is an integrated standardized squirrelcage motor. Refer to § 10.4 for specifications. If the
pump is to be used in potentially explosive
atmospheres, contact your Bredel representative.
4.7Motor frequency controller
Refer to the also s upp li ed documentation of the supplier
and § 10.5. If the pump is to be used in potentially
explosive atmospheres, contact your Bredel
representative.
4.8Available options
The next options are available for the hose pump:
•Revolution counter
•Drain connection
•Epoxy / titanium pressing shoes and titanium
shims
•Frequency controller

5INSTALLATION
5.1Unpacking
When unpacking carefully follow the instructions as
given on the packaging or on the hose pump.
5.2Inspection
Check that your delivery is correct and check it for any
transport damage. Refer to § 4.1.1. Report any damage
immediately to your Bredel representative.
5.3Installation conditions
5.3.1Ambient conditions
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.
5.3.2Set-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 10 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.
INSTALLATION
21
INSTALLATION
5.3.3Pipework
When determining and connecting suction and
discharge lines consider the following points:
•The bore size of the suction an d dis ch arge lin es
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 Yconnections 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 sh ort a nd
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 § 10.1.1. If necessary fit a pressure
relief valve.
CAUTION
Consider the maximum permissible working pressure on the discharge side.
Exceeding the maximum working pressure
may lead to serious damage to the pump.
•Make sure that the maximum forces on the
flanges are not exceeded. The permissible
loads are given in the following table.

CAUTION
In case of hose failure, the product or a
mixture of product and lubricant can leak
by the breather cap. If this risk is not
acceptable, dr ain piping can be connected,
refer to § 7.10.2.
WARNING
The maximum pump tem perature is 60°C.
Above this temperature the corrosion
speed can rise excessively, depending on
the product.
INSTALLATION
5.3.4Frequency controller
WARNING
A Bredel VFD that is fitted without the control switch starts automatically when pow er
is applied.
If the hose pump is fitted with a Bredel Variable
Frequency Drive (VFD), consider the following points:
•Take precautions so the motor does not re-start
automatically after an unscheduled stop.
In the event of a power or mechanical failure,
the Bredel VFD controls the motor to stop.
When the cause of the failure is removed, the
motor can restart automatically. The automatic
restart is dangerous to certain installations of
the pump.
23
INSTALLATION
•All control cables outside the enclosure must be
shielded and have a cross sectional area
between 0.22 and 1 mm
be connected to earth at both ends.
5.3.5High Level Control (HLC)
To sense the lubricant level inside the pump housi ng the
pump is provisioned with a floater. The HLC floater (A)
is positioned above the normal lubricant level of the
pump. When a hose fails, the product will be pressed
into the pump casing and causes a level rise of the
lubricant. The HLC shall detect this rise of lubricant.
After hose failure, the floater needs to be cleaned.
Connection of floaters:
The floater has to be connected to the auxiliary power
circuit via the 1 meter long PVC cable (2 x 0.24 mm

STORAGE
8STORAGE
8.1Hose pump
•Store the hose pump or pump parts in a dry
area. Make sure that the hose pump or pump
parts are not exposed to temperatures lower
than -40 °C or higher than +60 °C.
•Cover the openings of the inlet and outlet ports.
•Prevent corrosion of untreated parts. For this
purpose use the correct protection or packaging
means.
•After a long period of standstill or storage, the
static load on the pump hose may have caused
permanent deformation, which will reduce the
life of the pump hose. To prevent this, remove a
pressing shoe. Jog the rotor until the second
pressing shoe is positioned between the inlet
and outlet port. In this way there is no load put
on the pump hose.
8.2Pump hose
•Store the pump hose in a cool and dark room.
After two years the h ose m aterial will age , which
will reduce the life of the hose.
