DS Instruction Manual
1. Introduction
This manual forms an integral part of the pump and must accompany it until its
demolition. The series DS peristaltic pump is a machine destined to work in
industrial areas and as such the instruction manual must form part of the
legislative dispositions and the applicable technical standards and does not
substitute any installation standard or eventual additional standard.
1.1 Explanation of the safety information
1.2 Users’ qualifications
Pumps are machines that due to their functioning under pressure and moving
parts can present dangers.
- Improper use
- Removing the protections and/or disconnecting the protection device
3
Page 4
DS Instruction Manual
- The lack of inspections and maintenance
They can cause serious damage or injury.
The person in charge of safety should therefore guarantee that the pump is
transported, installed, put in service, used, maintained and repaired by qualified
personnel who should therefore possess:
- Specific training and sufficient experience.
- Knowledge of the technical standards and applicable laws.
- Knowledge of the general national and local safety standards and also
of installation.
Any work carried out on the electrical part of the pump should be authorized by
the person responsible for safety. Given that the pump is destined to form part
of an installation, it is the responsibility of whoever supervises the installation to
guarantee absolute safety, adopting the necessary measures of additional
protection.

Live parts
Possible consequence: Fatal or very serious injuries.
- Measure: 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
Possible consequence: Fatal or very serious injuries.
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
Possible consequence: Fatal or very serious injuries.
- Measure: Ensure that there can be no unauthorized access to the
unit.
Hazardous media/contamination of persons and equipment
Possible consequence: Fatal or very serious injuries material damage.
- 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.
DS Instruction Manual
2. Safety and Responsibility
2.1 General safety information
5
Page 6
- Observe the general restrictions in relation to viscosity limits,
chemical resistance and density.
- Always switch the pump off before exchanging the pump hose
Correct and proper use
Possible consequence: Fatal or very serious injuries.
- 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.
- 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.
- In the case of the hose becoming stuck during extraction or fitting
it is necessary to reverse the direction of the pump, relubricate,
and then repeat the operation.
- 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
Possible consequence: Fatal or very serious injuries.
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 rupture alarm
(optional) is fitted, then the pump can be stopped and / or an electrical
valve can be actuated.
DS Instruction Manual

Page 7
CIP cleaning
In the event of CIP cleaning, it is necessary to obtain information from
the manufacturer about correct installation of the pump (a special
installation is required) 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
Possible consequence: Material damage right through to destruction of
the unit.
- 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
Possible consequence: Personal injury.
You may only carry out work on the pump after it has previously been
switched off and disconnected from the mains.
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
DS Instruction Manual

Environmental influences
Possible consequence: Material damage right through to destruction of
the unit.
- 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.

3. Functional description
The DS Series is a displacement pump. The feed chemical is conveyed by the
rotor squeezing the hose in the direction of flow. No valves are needed for this.
This ensures gentle handling of the metered media.
The DS Series has been designed for safe and uncomplicated operation, as
well as straightforward maintenance.
The DS Series can be used for many different media. However, this pump type
is often the optimal solution for abrasive, shear-sensitive and viscose media.
Typical areas of use include processes where only a low discharge pressure is
required (max. 2 bar).
3.1 Construction
Main modules:
- Drive Unit
- Tubing
- Base frame
The pump housing is closed off with a screwed front cover in order to avoid the
risk of injury.
The motor serves to drive the rotor. Three rollers at the ends of the rotor serve
to press the pump hose against the pump housing.
The rotary movement of the rotors alternately press and relax the rollers in
relation to the pump tube. This serves to suck the media and convey it into the
metering line.

4. Transport and Storage
4.1 Transport
- The pump is protected by a cardboard packaging.
- The packaging materials are recyclable.
4.2 Storage
- The pump should be in a resting position. (The hose should not be
compressed).
- Avoid areas open to harsh weather or excessive humidity.
- For storage periods of longer than 60 days, protect the coupling surfaces
(clamps, reducers, motors) with adequate anti-oxidant products.
- Spare hoses should be stored in a dry place away from direct light.

5. Assembly and Installation
5.1 Ambient conditions
Assembly is to be carried out in the following order. If the pump has to be
installed outdoors, then it is to be equipped with protection against sunlight and
weather influences. When positioning the pump, ensure that sufficient room for
access is provided for all types of maintenance work.
Limit values for hose temperature and pressure
* At max. Tª, the life of hose is drastically reduced. Please contact with Boyser or
authorized distributor for high Tª application.
5.2 Correct installation of the pump
5.2.1 Suction side
The pump is to be positioned as near as possible to the liquid container, so that
the suction side is kept as short and straight as possible. The suction line must
be absolutely airtight and made of a suitable material, so that it is not squeezed
together under vacuum. The diameter must correspond to the rated diameter of
the pump tube. A larger diameter is recommended in the event of viscose
liquids. The pump is self-priming and does not require an admission valve. The
pump is reversible and the suction connection can therefore comprise of one of
two options. Normally the option is selected which is best suited to the physical
conditions of the installation. It is recommended to use a flexible transition
12
Page 13
DS Instruction Manual
between two fixed pipes and the hydraulic connection of the pump, in order to
avoid the transmission of vibrations.
5.2.2 Discharge side
The discharge line is to be kept as straight and short as possible, in order to
avoid performance reduction. The diameter must correspond to the rated
diameter of the pump tube. A larger diameter is recommended in the event of
viscose liquids. It is recommended to use a flexible transition between two fixed
pipes and the hydraulic connection of the pump, in order to avoid the
transmission of vibrations.
