2.2 Intended use
The hose pump is exclusively designed for pumping
suitable products. Every other or further use is not in
conformance with the intended use.
The "Intended use" as laid down in EN 292-1 is "... the
use for which the technical product is intended in
accordance with the specifications of the manufacturer,
inclusive of his indications in the sales brochure". In
case of doubt it is the use which appears to be its
intended use judging from the construction, execution
and function of the product. Observing the instructions
in the user's documentation also belongs to intended
use.
Only use the pump in conformance with the intended
use described above. The manufacturer cannot be held
responsible for damage or harm resulting from use that
is not in conformance with the intended use. If you want
to change the application of your hose pump, contact
your Bredel representative first.
2.3 Use in potentially explosive atmospheres
Refer to chapter 10 for a description of pump
configurations that are suitable in a potentially explosive
atmosphere. Such configurations are suitable for use in
a potentially explosive atmosphere. For use in Europe,
the pump complies with the European Directive 94/9/EC
(ATEX).
The pumps belong to:
•Group II Appliances, category 2 GD bck T5
Use in Potentially explosive atmospheres
requires special configuration of the pump
unit. Contact yourBredel representativefor
use in explosive atmospheres.

SAFETY

2.4 Responsibility
The manufacturer does not accept any responsibility for
damage or harm caused by not (strictly) observing the
safety regulations and instructions in this manual and
the also supplied documentation, or by negligence
during installation, use, maintenance and repair of the
hose pumps mentioned on the front cover. Depending
on the specific working conditions or accessories used,
additional safety instructions can be required.
Immediately contact your Bredel representative, if you
noticed a potential danger while using your hose pump.
2.5 Qualification of the user
The installation, use and maintenance of the hose
pump should only be performed by well-trained and
qualified users. Temporary staff and persons in training
may use the hose pump only under the supervision and
responsibility of trained and qualified users.
2.6 Regulations and instructions
•Everyone who works with the hose pump must
be aware of the contents of this manual and
observe the instructions with great care.
•Never change the order of the actions to be
carried out.
•Always store the manual near the hose pump.
WARNING
The user of the hose pump is always fully
responsible for observing the local valid
safety regulations and directives. Observe
these safety regulations and directives
when using the hose pump.

WARRANTY CONDITIONS
13
3 WARRANTY CONDITIONS
The manufacturer offers a two-year warranty on all
parts of the hose pump. This means that all parts will be
repaired or replaced free of charge, with the exception
of consumables, such as pump hoses, hose clamps,
ball bearings, wear rings, and seals, or parts which
have been misused or have been intentionally
damaged.
If parts are used that are not Watson-Marlow Bredel
B.V. (hereafter called Bredel) parts, every warranty
becomes void.
Damaged parts which are covered by the applicable
warranty conditions can be returned to the
manufacturer. The parts must be accompanied by a
fully filled in and signed safety form, as present in the
back of this manual. The safety form must be applied to
the outside of the shipping carton. Parts which have
been contaminated or which have been corroded by
chemicals or other substances which can pose a health
risk, must be cleaned before they are returned to the
manufacturer. Furthermore, it should be indicated on
the safety form which specific cleaning procedure has
been followed, and it should be indicated that the
equipment has been decontaminated. The safety form
is required at all items, even if the parts have not been
used.
Warranties purporting to be on behalf of Bredel, made
by any person, including representatives of Bredel, its
subsidiaries, or its distributors, which do not accord with
the terms of this warranty shall not be binding upon
Bredel unless expressly approved in writing by a
Director or Manager of Bredel.

A: Cover
B: Rotor
C: Pump hose
D: Pump housing
E: Support
F: Gearbox
G: Electric motor
H: Frequency controller
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

DESCRIPTION
18
(C). A bearing-mounted rotor (D) with two facing
integral pressing shoes (E) is in the centre of the pump
head.
In phase 1 the lower shoe compresses the pump hose
by the rotational movement of the rotor, forcing the 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.
In phase 2 the product is drawn into the hose by the
(continuous) turning motion of the rotor.
In phase 3, the second integral 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 shoe. When the first shoe
runs from the pump hose, the second 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".

4.4 Pump hose
4.4.1 General
A: Outer extruded layer made of natural rubber
B: Two 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.
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.
Hose type Material Colour code
NR Natural rubber Purple
NBR Nitrile rubber Yellow
EPDM EPDM Red
CSM CSM Blue
Consult your Bredel representative for
more detailed information about the chemi-
cal and temperature resistance of pump
hoses.

DESCRIPTION
20
•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
The compression force of 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. If you want
to change the application of your hose pump, contact
your Bredel representative.
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.
4.5 Gearbox
The hose pump types described in this manual use
helical gearbox units. The gearboxes are fitted with a
flange connection. Refer to § 11.2 for specifications. If
the pump is to be used in potentially explosive
atmospheres, refer to chapter 10.
Consult your Bredel representative for
lubrication recommendations when operat-
ing the hose pump below 2 rpm.
