INSTRUCTION MANUAL
DulcoFlex Peristaltic Pump: DFB13/RAD13
This manual forms an integral part of the pump and must accompany it until its demolition. The 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.
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 posses:
- 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.
GENERAL SAFETY WARNING
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
- The lack of inspections and maintenance
CAN CAUSE SERIOUS DAMAGE OR INJURY

TRANSPORT and STORAGE
TRANSPORT
The pump is protected by a cardboard packaging.
The packaging materials are recyclable.
During transportation, the pump is in a resting position (the hose is not compressed)
STORAGE
The pump should be in a resting position. (The hose should not be compressed).
Avoid areas open to inclement weather or excessive humidity.
For storage periods of longer than 60 days, protect the coupling surfaces with
adequate anti-oxidant products, remove hose/tube or remove one roller and rotate
remaining roller out of contact with hose/tube.
Hose/tube spares should be stored in a dry place away from direct light.

GENERAL SAFETY STANDARDS
The instructions of this manual, whose inobservance is
determined as a failure to meet safety standards, are
identified by this symbol
The instructions of this manual, whose inobservance
compromises electrical safety.
The instructions of this manual, whose inobservance
compromises the correct working of the pump, are identified
with this symbol.
Do not start the pump without first having installed the front cover.
For any manipulation of the equipment, it is necessary to make certain that the
pump is stopped and the electricity supply disconnected.
Changing the hose should be done with the pump stopped.
Do not exceed the nominal pressure, speed or temperature of the pump, or
use the pump for applications other than that originally planned without first
consulting the manufacturer.

Cleaning the pipe, including the hose, should be done with fluids compatible
with the mentioned drive pump and at its maximum temperature
recommended.
Do not start the pump without it being properly secured to the floor - unless
cart mounted.
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.
The start system of the motor should be provided with a direction inverter,
stop-go button and emergency stop button (together with the pump), in such a
way that the pump can be manipulated with total safety.
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.
The DulcoFlex pump is a positive displacement pump and therefore
susceptible to a closed valve (dead headed) condition. Installing a pressure
relief valve on the discharge piping can help prevent damage caused by a
“dead headed” condition.
Check the turning direction of the pump, as it is reversible it could generate
pressure in the suction and compromise the safety of the installation. The
circulation of the fluid should be in the same direction as the turning direction
of the pump as seen from the inspection plate situated on the front cover.
Since hose/tube life is so unpredictable, it may be necessary to equip the
pump with a moisture sensing device that can shut the pump down in the
event of a hose/tube failure.
For C.I.P. type cleaning process, it’s necessary to check with the manufacturer
the correct installation of the pump (it’s necessary to use a special
installation), and also the compatibility of the cleaning products with the
peristaltic hose.

Construction of the pump.
As shown in the figure below, the pump unit is a very simple design, robust and with very few moving
parts.
The outer casing (1) terminates with threading connectors. Inside the casing are found the rotor (2),
completed with two rollers (3). As this is revolving it compresses the reinforced tube (4) and in this way
generates a pumping action. A change in the direction of rotation will give rise to a change in direction of
the pumped fluid.
INSTALLATION
PERISTALTIC PUMP

Installation should normally be made in a well ventilated area away from heat sources. If it is
necessary to place the pump outside it should be provided with a cover to protect it from sunlight and
inclement weather.
The positioning of the pump should allow easy access for all kinds of maintenance operations.
Suction. The pump should be as near as possible to the supply of liquid so that the suction pipe is as
short and straight as possible. The suction pipe should be perfectly airtight and made of suitable material
so that it does not collapse due to the internal drop in vacuum. The minimum diameter should be similar
to that of the tubular element. With viscous fluids a larger diameter is recommendable. (Consult
manufacturer or distributor).The pump has automatic suction and does not need an inlet valve. The
pump is reversible, and so the suction connection can be either one of the two. (Normally the one which
adapts itself physically better to the installation would be chosen). It is recommendable to use a
flexible connection between the piping and the pump flanges/fittings in order to avoid the
transmission of vibration to the piping.
Discharge. To reduce power being absorbed, use the straightest and shortest piping possible. The
diameter should be the same as the nominal diameter of the pump, excepting precise calculations of load
losses. With viscous fluids a larger diameter is needed. (Consult the manufacturer or distributor).
Connecting the fixed piping to the pump with a length of flexible pipe facilitates maintenance and avoids
vibrations and loads on the pump. Tighten all piping firmly. The discharge is slightly pulsatory: To avoid
such effect, it is advisable to install pulsation dampeners. (See accessories.)
ROLLER PRESSURE ADJUSTMENT
The peristaltic pump, includes a shims (Figure 6 ), that are used to adjust the exact pressing distance of
the roller ( figure 9 ).
The shims are installed from factory to work at the work conditions indicated ( in function of the speed and
the work pressure), and following the next tables.NOTE: If not indicated on original order, the
pumps are factory set to 60 psi.
