4.3 Operation 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
hose are connected to the suction and discharge lines

B

G

16

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.

DESCRIPTION

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.

In phase 3, the second pressing shoe will subse quently
compress the pump hose. Due to the continuous
rotating movement of the rotor not onl y 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 displacement principle".

DESCRIPTION

4.4 Pump hose

4.4.1 General 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 hos e ty pe i s marked by
a unique colour code.

Hose type Material Colour code

NR Natural rubber Purple
NBR Nitrile rubber Yellow
EPDM EPDM Red
CSM CSM Blue

A

B C

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 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.

18

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.

DESCRIPTION

B

A

The paragraph 8.8 describes how to select and install
the shims.

4.4.3 Lubrication 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.

The lubricant is food grade. See § 11.1.4 for the
required quantity and NSF registration.

Consult your Bredel representative for
lubrication recommendations when operat­ing the hose pump below 2 rpm.

4.5 Gearbox

4.5.1 General

The hose pump types described in this manual use a
bevel-helical gearbox. The gearbox is mainly used for
high reduction ratios and low input speeds. This
modular construction enables a wide range of
reductions, torques and connection possibilities for the
electric motor.

C

19

DESCRIPTION

4.5.2 Maintenance

For all information on maintenance and lubrications,
see the manual of the gearbox.

Check the oil level regularly. If necessary, refill the oil
level. Avoid mixing oils of different types. In case
of doubt, change the oil completely. Also check that
there are no metallic parts with unusual dimensions in
the oil.

Special attention must be paid to very loaded output
stages and with very low speeds (<1 rpm). In such
cases, always use high viscosity oils with a good
amount of Extreme Pressure (EP) additive.

Gearboxes, which are not particularly loaded and that
have a discontinuous operating cycle without
considerable temperature ranges, can be lubricated
with mineral oil.
When the gearboxes are heavily loade d and used in a
continuous way, this can result in temperature increase.
In this case, it is best to use polyalphaolefin synthetic
lubricants (PAO). Use a synthetic lubricant when the
ambient temperature is below -20 °C.
For special applications where high powers and speeds
are involved, consult your Bredel representative.

4.6 Electric motor

The standard-supplied electric motor is a completely
enclosed three-phase asynchronous motor.
The interface between motor and gearbox is an IEC or
Nema flange.
The motor connection must meet the local applicable
regulations. A thermal safety device should reduce the
risk of a motor overload. For connecting PTC
thermistors (if present) a special thermistor relay must
be used.
In case of doubt, contact your Bredel representative for
advice.

INSTALLATION

5 INSTALLATION

5.1 Unpacking

When unpacking, carefully follow the instructions as
given on the packaging or on the hose pump. This also
applies to the unpacking of the geabox and the electric
motor.

5.2 Inspection

Check that your delivery is correct and check it for any
transport damage. Also when replacing parts, check
that the delivery of the replacement parts is correct and
check them 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

Temperature

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.
The minimum start-up temperature for the gearbox
is -10 °C. A heater is required for tempertures below

-10 °C.

Atmospheric humidity

When the unit must be stored for a lo ng period of time,
especially in humid conditions, fill the gearbox
completely with oil and protect the machined parts with
rust inhibitors.
For extreme conditions, special precautions must be
taken. Contact your local Watson-Marlow
Bredel representative for additional information.

22

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.

• Position the pump on a horizontal surface. Use

suitable anchor bolts to attach the pump to the
floor surface.

• 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 and discharge lines

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.

• Keep the piping at a minimum equal to or

greater than the bore size of the pump. Increase
the bore size of the pipe work when the duty
fluid has a high velocity or inertia. This will help
keep friction and impulse losses to a mi nimum.
Where critical velocities are a concerned,
consult your Bredel representative.

INSTALLATION

1m

max 10 mm

23

INSTALLATION

• For the flexible hoses select compatible

materials and ensure the installation is suited
for the design pressure of the system.

• 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.
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.

• Consult your Bredel representative for

recommendations on mounting pulsation
dampening devices. A pulsation dampener and/
or inlet pulse accumulator may be necessary if
the relative density and and pump speed is high
and the line lengths are long.

• The self-priming and positive displacement

nature of peristaltic pumps means that valves
are not required. If for whatever reason valves
are fitted into the system, they must have a
straight fluid path and cause minimum
restriction to flow in the pumping circuit. Note
that the presence of check valves directly in the
process stream may increase pulsation and
negatively impact hose life.

• For the ease of hose changing and some

pulsation suppression, it is recommended to
use a segment of flexible hose between the
pump flange and hard piping of the suction and/
or discharge line. A segment of three quarters
(3/4) of the pump hose length for the flexible
pipe work is recommended. Bredel also
recommends installing an isolation valve and
pipe-drain in the suction and discharge

24

pipework to allow fluid isolation and drainage
from the pump during maintenance. Following
these recommendations will help to minimize
the exposure of process fluid to maintenance
personnel.

• Make sure that the maximum forces on the

flanges are not exceeded. The permissible
loads are given in the following table.

OPERATION

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.
Under conditions of high pressure and running speed,
casing and cover temperatures can reach values of
over 65 °C.
Under these conditions a person should not be in direct
contact with the pump surface to avoid injury by
burning.

WARNING

Do not touch the pump surface during
operation. The pump can run very hot.

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 these powers at
the given revolution speeds.

32

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.

Check the rated powers of the motor and
gearbox as indicated on the name plate
and check these with the power ratings
required for your operating condition.

7.3 Dry running

Dry running is a running condition of the pump when no
process flow (pumped product) is flowing through the
pump. The Bredel peristaltic pumps are very suitable for
dry running.
Dry running does impose an additional thermal lo ad on
the pump hose, because the internal heat associated
with repetitive hose compression is normally removed
by convection of the process fluid. So dry running
increases the wear of the hose. The magnitude of the
thermal load depends on the size and running speed of
the pump as well as the amount of shims mounted on
the rotor. To minimize the extra wear, it is advised to
minimize the dry running periods.

34

WARNING

Do not apply dry running in combination
with a flammable process fluid. In case of
doubt, consult your Bredel representative.

7.4 Hose failure

The hose in a peristaltic pump has to withstand many
load cycles of considerable magnitude. The repetitive
stress cycles will deteriorate the hose and will
eventually cause hose failure. The hose life strongly
depends on the operating condition, process fluid and
hose material. The end-user should be aware of this
and accept the need for regular hose replacement.
A hose failure will result in direct contact between the
pump lubricant and the pumped medium. In general,
this will not cause a hazardous situation as the Bredel
Genuine Hose Lubricant is harmless (FDA approved),
but it will result in additional downtime since the pump
needs to be cleaned prior to new hose installation.

WARNING

Exceptions to this general rule are when
the pumped product is either a strong oxi­dizer or a strong acid. These products
should be avoided as they can cause
unwanted chemical reactions with the
Bredel Genuine Hose Lubricant and a
hazardous situation may arise. In such
cases an alternative lubricant should be
used. Contact your Bredel representative
for more details.

OPERATION

These consequences can be avoided by preventive
hose replacement. The moment for preventive
maintenance depends on the particular application and
use of the hose. The end-user needs to find out the
moment for preventive maintenance.

7.5 Fluid leakage

The Bredel pump series uses lubricated shoes to
compress the hose. This means the pumphead must be
filled with a sufficient amount of lubricant during
operation. This lubricant is contained in the pump

35

OPERATION

housing by the cover on the front side and by a dynamic
seal on the back side. The gearbox is also filled with
lubricant.

Seal damage can occur due to normal wear in time, but
is seriously accelerated if the seal gets in contact with
contaminated fluid (during hose failure). Thorough
cleaning of the pump housing after a hose failure is
strongly advised.

Both the pumphead and gearbox are directly coupled to
each other. A special feature is included in the
pumphead to enable early detection of seal damage of
the pump or gearbox.

This feature is called the leakage zone. When a seal
starts to show increased leakage, this can be detected
at the back side of the pump. When drops of lubricant
are visible, it indicates upcoming 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.

36

Regularly inspect the pump on fluid leak­age.

WARNING

Risk of injury from falling! Process fluid
mixed with pump lubricant that is leaking
from the pump can lead to slippery floors.

8 MAINTENANCE

B
C

A

Fitting and removing shims is a simple action which can
be carried out via the inspection window on the front of
the pump housing. The pump hose or the pump cover
does not need to be removed. In order to determine the
correct number of shims for your specific application
refer to § 11.1.7.

CAUTION

Too many shims, this means a too high
compression force on the pump hose, cre­ate a too high load on the pump head and
pump hose, which results in a reduction of
the life of the pump hose and bearings.

55

MAINTENANCE

CAUTION

Too few shims, this means a too low com­pression force on the pump hose, create a
loss of yield and slip or backflow. Backflow
results in a reduction of the life of the pump
hose.

1. Jog the motor until the pressing shoe (B) is
positioned in view of the inspection window (A).

2. Isolate the pump from the electrical supply.

3. Place a tray (A) under the drain plug (B) in the
bottom of the pump head. Remove the drain
plug. Drain as much Bredel Genuine Hose
Lubricant until the level has lowered just below
the inspection window (D). Check that the
sealing ring (C) is not damaged and replace it if
necessary. Position the drain plug and tighten it
firmly.

4. Loosen the retaining bolts (A) of the insp ection
window (B) and remove the bolts. Remove the
inspection window. When doing this prevent the

9 STORAGE

9.1 Hose 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 +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
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.

9.2 Pump hose

STORAGE

• 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.

9.3 Electric motor and gearbox

• When the unit must be stored for a long period

of time, especially in humid conditions, fill the
gearbox completely with oil and protect the
machined parts with rust inhibitors.

• For further requirements regarding storage of

the electric motor and the gearbox, see the
supplied documentation of the electric motor
and gearbox.
