THE FOLLOWING CAN CAUSE SERIOUS DAMAGE AND INJURY:
- Improper use
- Removal of the protections and/or disconnection of protective devices
- Lack of inspections and maintenance
The person responsible for safety should therefore guarantee that the pump is transpor-
ted, installed, put in service, used, maintained and repaired by qualified personnel who
should possess:
- Specific training and sufficient experience for the tasks.
- Knowledge of the technical standards and applicable laws.
- Knowledge of the national and local safety and installation standards.
Any work carried out on the electrical part of the pump should be authorized by the per-
son responsible for safety.
Given that the pump is intended to form part of a system, it is the responsibility of whoever
supervises the installation of the entire system to guarantee absolute safety, adopting the
necessary measures of additional protection.
2.5. General safety information
Live parts
Possible consequence: fatal or very serious injuries.
- Risk mitigation: 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.
Lack of emergency stop switch
Possible consequence: fatal or very serious injuries.
- An emergency stop switch must be connected for the entire system.
This should enable the entire system to be shut down in the event
of an emergency in such a way that the overall system can be brou-
ght into a safe condition.
Unauthorized access
Possible consequence: Fatal or very serious injuries.
- Risk mitigation: ensure that there can be no unauthorized access to
the pump or to the system.
Hazardous media/contamination of persons and equipment
Possible consequences: Fatal / serious injuries, material damage.
- Ensure that the tubes are chemically resistant against the media

5
being handled.
- Always observe the safety data sheets for the media to be handled.
The system operator must ensure that these safety data sheets are
available and that kept up-to-date.
- The safety data sheets for the fluid being handled are always deci-
sive for initiating countermeasures and/or first aid in the event of
leakage of the fluid.
- Observe the general restrictions in relation to viscosity limits, che-
mical resistance and density.
- Always switch the pump off before exchanging the tube.
Incorrect and improper 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.
- Maximum pressure on suction/inlet side is 0,5 bar (7 psi approx.).
- 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.
- This pump is NOT supplied for use in areas of risk from explosion.
ATEX versions of BOYSER pumps are available and they are supplied
with a special ATEX version of the instruction manual.
- Only switch the pump on if it has been properly fastened to the
floor.
- Only switch the pump on if 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 pres-
sure and are empty or isolated.
- In the case of the tube becoming stuck during extraction or fitting it
is necessary to reverse the direction of the pump, re-lubricate, 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 pres-
sure, 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 tubes
Possible consequence: fatal or very serious injuries.
- The tube has an indeterminate life and due to the possibility of its
breakage or deterioration, the user is responsible for the preven-

6
Operating instruccions Peristaltic Pumps DSM Series
tion of a possible (although most unlikely) incorporation of particles
from the tube into the product being pumped. This can be achieved
by means of filtration, a tube rupture alarm or other means suitable
for the respective process
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 compati-
bility of the cleaning agents with the tubes and the hydraulic con-
nections.
- Cleaning should be undertaken at the recommended maximum
temperature.
Direction of rotation/flow direction
Possible consequence: material damage, destruction of the unit.
- The pump’s direction of rotation in relation to the desired flow di-
rection must be checked prior to every start.
Disconnect the pump from the mains

3. Functional description
The DSM Series is a positive displacement pump. The feed chemical is conveyed by the
rotor squeezing the tube in the direction of flow. No valves are needed for this. This ensu-
res gentle handling of the metered media.
Maximum pressure on suction/inlet side is 0,5 bar (7 psi approx.).
The DSM Series has been designed for safe and uncomplicated operation, as well as
straightforward maintenance.
The DSM Series can be used for many different media. However, this pump type is often
the optimal solution for abrasive, shear-sensitive and viscous media.
Typical areas of use include processes where only a low discharge pressure is required
(max. 2 bar).

5. CONSTRUCTION
The pump housing is closed off with a bolted front cover in order to avoid the risk of injury.
The motor serves to drive the rotor. Two shoes attached to the rotor serve to press the
tube against the pump housing.
The rotary movement of the rotor alternately presses and releases the shoes against the
tube. This serves to suck the media and convey it into the metering line.

7.2. Commissioning
7.2.1. Testing prior to commissioning the pump
The following tests are to be carried out:
- Only switch the pump on if the front cover has been properly attached.
- Check that the mains voltage is suitable for the motor.
- Check that the thermal overload protection (not included in the delivery scope)
corresponds to the value specified on the motor type plate.
- Confirm that pump has been properly earthed.
- Connect the electric motor according to local applicable rules and regulations. The
electrical installation work must be carried out by qualified personnel.
- Check that the optional electrical components are connected and are working
properly.
- Check whether the direction of rotation is correctly adjusted.
7.3. Correct installation of the pump
- Ensure that the pump has not been damaged during transportation or storage.
Immediately report any damage to the supplier.

12
Operating instruccions Peristaltic Pumps DSM Series
- Ensure that all the packaging has been removed.
- Check that the information printed on the identification plate corresponds with
the order.
- Check the operating instructions in order to ensure that the flow values, pressures
& power consumption of the motor do not exceed rated values.
- Ensure that the tube is suitable for the fluid to be conveyed and that it is not
damaged.
- Make sure that the temperature of the liquid does not exceed the recommended
temperature range.
- Ensure that there is enough space for free airflow around the motor.
- Ensure that no nearby objects or direct sunshine radiate additional heat to the
motor.
7.3.1. Suction side
- Install a manometer in the pressure line if the back-pressure value is unknown.
Maximum pressure on suction/inlet side is 0,5 bar (7,25 psi approx.).
- 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 does not collapse under vacuum.
- The diameter must correspond to the rated diameter of the tube. A larger diameter
is recommended in the event of viscous liquids.
- The pump is self-priming and does not require an admission valve.
- The pump is reversible and the suction side can be connected to either hydraulic
connection of the pump. Normally, the option is selected which is best suited to
the physical conditions of the rest of the installation.
7.3.2. 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 tube. A larger diameter
is recommended in the event of viscous liquids.
- Do not close or block the outlet since, as it is a volumetric pump, it would cause
the tube to break or an electro-mechanical overload.
