GENERAL INTRODUCTION

Peristaltic pumps pump all kinds of liquid substances without coming into contact with mechanical elements

as in other pumps.

They are easy to use with minimal maintenance.

The pumped substance is impelled into an elastic tube by the vacuum generated by rotors that successively

press and release the surface of the tube.

The liquid passes directly from its container to another without any contamination and without going back

when the pump stops, since the tube remains pressed by the roller.

Some aggressive substances prevent the use of conventional pumps and make peristaltic pumps very

useful for the transfer or dispensing of such substances.

Flow rates are obtained from 0,02ml/minute up to 6000ml/minute.

A large number of different size tubes or hoses made of materials resistant to various hazardous

substances are available.

The following instructions are intended to ensure correct reception and use of the device, and the safety of

the user.

To this end, we recommend reading this manual in detail before proceeding to unpack the device and

subsequent use.

For proper conservation of the device, it is necessary to avoid its installation in areas with corrosive

atmospheres or exposed to liquid splashes.

Avoid using the device when there is the possibility of generating explosive and flammable gas mixtures.

DESCRIPTION

The D-25Vplus peristaltic pumps in this manual mount the 153-3r head that allows easy access to the tube

for removal when it must be replaced.

On the easy-load 153-3r head, simply pull up and to the left of the lever (1) located on the top right of the

head to raise the top and open the head for tube replacement.

When removing the tube, slide the buttons (3) up to move the tube retainers.

The head admits various tube sizes which, combined with the speed regulation, gives a great variety of

flows, as can be seen in the flow chart

With the FULL key, no. 3 in the description on the front panel, the maximum speed ofthe motor is obtained,

in the loading, purging and cleaning operations.

Keys 1 and 2 allow choosing the direction of rotation of the motor for flow inversion.

On the back is the connection for the network cable with integrated fuse holder, connection for pedal and

input for analog signal 0-10 V and 4-20 mA

Consult the indicative table of dosages and install the appropriate tube.

2 - Tractor axle output guard

3 - Sliding buttons for fixing the peristaltic tube

4 - Complementary head fixing screw holes

The 153-3r head admits another equal head on its same axis of rotation. Remove the protector 2 to face

the complementary head with the axis and insert the two assembly screws in the holes 4.

With 2 heads it is possible to cancel the typical cadenceof the peristaltic flow. To do this, when locating the

complementary head, the rotor rollers must be oriented in opposition to the main head rollers.

When the heads are used as independent channels, each one will provide the flow corresponding to the

tube installed in the heads.

If it is intended to double the flow, the two suction and discharge tubes can be installed directly in the

feeding and receiving containers.

The option of using a Y connection to join the tubes of both heads (1) will allow the cancellation of the

peristaltic pulse. It must be remembered that the final discharge tubes and especially the suction ones must

be of a larger diameter than the head tube. If this is not possible, the total flow will be somewhat less than

the theoretical expected.

NOTE:

While using the 0-10V and rear 4-20mA analog input, the ramp and cycle functions are not accessible.

The footswitch connection is active during use of the footswitch pump and cycle function.

When using the 0-10V / 4-20mA regulation, the regulation keys 5 and 6 are inactivated.

6- CHANGE OF TUBES

Press the OFF switch. Extract the tube according to the indications described in the “Description” and

“Head” section.

When the new tube is installed, it should be centered over the rollers to prevent the rotor from pinching it.

Check that the pump is OFF.

On the sides of the head where the peristaltic tube enters and exits, a sliding button acts on the tube fixers.

Slide the button to release or clamp the tube. When the button is released, it recovers the position by itself.

In general, new tubes can stretch during the first 30 minutes of operation. If this happens, they must be

tightened again to avoid unexpected breakage. To detect the elongation of the tube to the head it is useful

to conveniently mark the tube with a marker .

Due to the fact that the friction of the tubes with the rollers increases with the diameter of the tubes, the

minimum adjustable speed increases the greater the diameter of the tube.

It is not advisable to use a lower speed, even if the motor starts, sinceat any moment it can stop and cause

the regulation circuit to overheat, which could be damaged if it remains in this situation for a long time.

It is desirable to use a speed somewhat higher than the minimum observed speed.

When using two heads at the same time, it may be necessary to limit the diameter of the tubes to be used,

especially with tubes of high hardness.

The pump supply and discharge tubes can have any wall thickness, but not the tube that is installed in the

head, whose wall must be 1,6mm,

The silicone tubes supplied with each pump are medical / food grade according toFDA and USP standards,

autoclavable at 120º C, with a peristaltic range of use up to 80º C and medium duration.

Other materials available are:

The most mechanically resistant tubes are PHARMA, TYGON L ®, TYGON A-60-C ® , TYGON A-60-G ®

and medium-duration SILICONE and VITON®

However, the durability also depends to a large extent on the chemical nature of the pumped liquid, the

pressure, the existing temperature and naturally the engine revolutions.

Proper choice of tubing ID prevents higher RPM demand from the peristaltic pump motor with small

diameter tubing and decreased tubing life.
