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.

INSTRUCTION MANUAL

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.

WARNING!

DFB13/RAD10

INSTRUCTION MANUAL

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.

GENERAL DESCRIPTION

WARNING!

DFB13/RAD10

INSTRUCTION MANUAL

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

DFB13/RAD10

INSTRUCTION MANUAL

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.
