4.3 Operation of the pump
The heart of the pumphead consists of a specially
constructed pump hose (A) which lies against the inside
of the pump housing (B). The ends of the hose are
connected to the suction and discharge lines (C). A
bearing-mounted rotor (D) with two facing integral
pressing shoes (E) is in the centre of the pumphead. It
rotates clockwise.
In phase 1 the lower shoe compresses the pump hose
by the rotational movement of the rotor, forcing fluid
through the hose. As soon as the shoe has passed, the
hose recovers to its original shape due to the
mechanical properties of the material and fluid is drawn
into the hose.
In phase 2 fluid is drawn through the hose by the
(continuous) turning motion of the rotor.
DESCRIPTION
AB E CD
In phase 3, the second integral pressing shoe
compresses the pump hose. Due to the continuous
rotating movement of the rotor new fluid is sucked in
and fluid that is previously drawn in is pressed out by
the shoe. When the first shoe leaves the pu mp hose,
the second shoe has already occluded the pump hose
and fluid is prevented from flowing back. This method of
liquid displacement is known as the "positive
displacement principle".

A
B C
Consult your Bredel representative for
more detailed information about the
chemical and temperature resistance of
pump hoses.
Bredel pump hoses have been carefully machined to
achieve 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 an
excessive load on the pump and pump hose,
which may reduce the life of the pump hose and
bearings.
• When the compression is too low, it cuts
capacity and causes backflow. Backflow
reduces the life of the pump hose.
18
4.4.2 Hose compress ion force adjustment
The compression force on the pump hose can be
adjusted by installing a rotor with a different dimension
between the tips of the integral pressing shoes. The
rotor is chosen to achieve an optimal life of the pump
hose for the intended use of the hose pump. Each hose
size (10, 15 or 20 mm inner diameter) has its own lowpressure and medium-pressure rotors. This means
there are six types of rotors available. If you want to
change the application of your hose pump or if you want
to change the hose size, contact your Bredel
representative.
Low-pressure and medium-pressure rotors can be
recognized by a marked hole near the “L” for “Lowpressure” (B) or near the “M” for “Medium-pressure” (A)
on the rotor.
DESCRIPTION
A
B
4.4.3 Lubrication and cooling
The pumphead is filled with Bredel Genuine Hose
Lubricant. This lubricant lubricates the shoes and
dissipates the heat generated by the movement of the
pressing shoes against the pump hose.
The lubricant is food grade. The user is responsible to
ensure the chemical compatibility of the lubricant with
the fluid to be pumped. Refer to § 11.1.4 for the
required quantity and NSF registration.
Refer to § 7.5 for the consequences of a hose failure.
Consult your Bredel representative for
lubrication recommendations when
operating the hose pump below 2 rpm.
19
DESCRIPTION
4.5 Gearbox

5INSTALLATION
5.1 Unpacking
Follow the unpacking instructions on the packaging or
on the hose pump, the gearbox and the electric motor.
5.2 Inspection
Check that your delivery is correct and check it for any
transport damage. When replacing parts, check that the
delivery is correct and check these parts for any
transport damage. Refer to § 4.1.1. 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 °C and not higher than +45 °C.
INSTALLATION
5.3.2 Setup
• The pump materials and protective layers are
suitable for indoor setup and a protected
outdoor setup. Under certain conditions the
pump is suitable for limited outdoor setup or a
salty or aggressive atmosphere. Consult your
Bredel representative for more information.
• Make sure that the floor surface 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.
• Make sure that the room is sufficiently
ventilated, so that the heat developed by the
pump and drive can be dissipated. Keep some
distance between the ventilation cover of the
electric motor and the wall to allow the supply of
cooling air.
21
INSTALLATION
5.3.3 Pipework
When determining and connecting suction and
discharge lines consider the following points:
• It is recommended that the bore size of the
suction and discharge lines is 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 any
bend is as large as possible. 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 l ines
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.
• Do not exceed the maximum working pressure
of the hose pump. Refer to § 11.1.1. 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.

5.3.5 Frequency controller
WARNING
A frequency controller that is fitted without
manual control can start the pump
automatically when power is applied.
If the hose pump is fitted with a frequency controller,
consider the following points:
• Take precautions so the motor does not restart
automatically after an unscheduled stop.
In the event of a power or mechanical failure,
the frequency controller stops the motor. When
the cause of the failure is removed, the motor
can restart automatically. The automatic restart
can be dangerous in certain pump installations.
23
INSTALLATION
• All control cables outside the enclosure must be
shielded and have a cross sectional area
between 0.22 mm

7 OPERATION
7.1 Temperature
The pump will heat up during normal operation. Heat is
generated in the contact zone between the pressing
shoe and the hose. The heat is removed by the
lubricant and transported to the pump casing and cover.
This will result in a temperature higher than the ambient
temperature.
WARNING
Avoid contact with the casing and cover
under conditions of high pressure and
running speed.
7.2 Power rating
The pump requires a certain amount of power for the
specified operating condition(s). The gearbox and
motor should be capable of handling that power at the
given revolution speeds. Refer to § 7.3 to determine the
required power.
OPERATION
WARNING
Overloading the motor can lead to serious
motor damage. Do not exceed the
maximum power rating of the motor.
WARNING
Overloading the gearbox leads to
increased tooth wear and shortened
bearing life. This can lead to serious
gearbox damage. Do not exceed the
maximum power rating of the gearbox.
27
OPERATION
7.3 Performance graphs
Useful operating duties can be found in the
performance graphs in which discharge-pressure
curves are displayed in a speed-power diagram.
Even at 0 kPa discharge pressure a certain torque is
required to let the pump rotor rotate. The pump and
hose are designed to handle a discharge pressure up to
800 kPa. The triangular area between the 0 kPa and the
800 kPa lines describes the allowed performance area.
The required duty points have to fall within this area.
In the direction of higher speeds and powers, pump
operation is limited by the heat generated, the product
temperature and the ambient temperature. Producttemperature lines determine a distinction between
areas of continuous operation and intermittent
operation in the graphs. The graphs apply for a
maximum ambient temperature of 40 °C.
If the duty for an application is specified in the area of
intermittent operation, let the pump stand still to cool
down for at least one hour after three hours of
operation.

7.4 Dry running
Dry running is a running condition of the pump when no
fluid is flowing through the pump. Bredel peristaltic
pumps are very suitable for dry run nin g.
Dry running imposes an additional thermal load on the
pump hose, because a part of the internal heat
associated with repetitive hose compression is normally
removed by the process fluid. So dry running increases
the wear on the hose. The thermal load depends on the
running speed of the pump, the hose size (10, 15, 20
mm) as well as the rotor type (low pressure or medium
pressure). To minimise the extra wear, it is advisable to
minimise dry running periods.
30
7.5 Hose failure
Cause of a hose failure
The hose in a peristaltic pump has to withstand many
load cycles of considerable magnitude. The repetitive
stress cycles will cause the hose to deteriorate and
eventually fail.
Result of a hose failure
A hose failure will result in direct contact between the
pump lubricant and the pumped fluid.
Consequences of a hose failure
In general, this will not cause a hazardous situation
because the Bredel Genuine Hose Lubricant is
harmless (approved by the United States Food and
Drug Administration). However, there is an exception in
case of pumping a strong oxidiser or a strong acid.
Refer to § 11.1.4 about chemical compatibility.
OPERATION
31
OPERATION
• Hazardous situations
WARNING
Avoid direct contact between a strong
oxidiser or a strong acid and Bredel
Genuine Hose Lubricant. This can cause
unwanted chemical reactions. Use an
alternative lubricant to avoid hazardous
situations. Contact your Bredel
representative for more details.
• Additional downtime
Hose failure will result in additional downtime,
because you must clean the pump before a new
hose installation.
Regularly replace the hose to avoid hose
failure and additional downtime. Hose life
depends on the operating condition,
process fluid and hose material. The enduser should be aware of this and establish
the frequency of preventive hose
replacement. Contact your Bredel
representative for advice.
• Large spill of product
In case the pressure in the process line
(reservoir) is above the pressure in the pump
housing (ambient pressure), the process fluid
can enter the pump housing. If there is no check
valve in the process line a serious amount of
fluid can flow from the reservoir into the pump
housing and escape through the breather onto
the floor. This could lead to a large spill of
product outside the pump. Reversed flow
protection is advised. This is not part of the
scope of delivery.
32
7.6 Fluid leakage
The APEX pump uses a lubricated rotor to compress
the hose. This means the pumphead must be filled with
sufficient lubricant during operation. This lubricant is
contained in the pump housing by the front cover and
by a dynamic seal on the back. The gearbox is filled
with gearbox lubricant.
Seal damage can occur due to normal wear in time, but
is seriously accelerated if the seal gets in contact with
contaminated lubricant. Thorough cleaning of the pump
housing after a hose failure and regular replacement of
the lubricant is strongly advised.
The pumphead and gearbox are directly coupled to
each other. A special feature is included in the
pumphead to allow early detection of seal damage of
the pump or gearbox.
This feature is called the leakage zone. Drops of
lubricant visible at the back of the pump indicate likely
seal failure. To avoid consequential damage, the pump
must be stopped and lubricant levels of the pumphead
and gearbox must be checked. The damaged seal
should be replaced.
OPERATION
Regularly inspect the pump for fluid
leakage.
WARNING
Risk of injury from falling! Process fluid
mixed with pump lubricant that is leaking
from the pump can make floors slippery.

supply, wait two minutes to make sure that
the capacitors have discharged.
WARNING
Do not remove the pump cover if the power
cable is connected to the motor. Do not
connect the power cable to the motor if the
pump cover is removed.
Only use original Bredel parts when maintaining the
hose pump. Bredel cannot guarantee correct operation
and any consequential damage that occurs from the

9.1 Hose pump
• Store the hose pump and pump parts in a dry
area. Make sure that the hose pump and pump
parts are not exposed to temperatures lower
than -40 °C or higher than +70 °C.
• Cover the openings of the inlet and outlet ports.
• Prevent corrosion of untreated parts. For this
purpose use the correct protection or
packaging.
• 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
the pump hose when the pump is not going to
be used for more than one month.
9.2 Pump hose
• Store the pump hose in a cool and dark room.
After two years the hose material will age, which
will reduce the life of the hose.
