1- GENERAL INTRODUCTION
Peristaltic pumps, pump all kinds of liquid substances without encountering mechanical elements as occurs in
other pumps. They are easy to use and require minimal maintenance.
The pumped substance is impelled inside an elastic tube thanks to the vacuum generated by a set of rotors that
successively press and release the surface of the tube. The liquid passes directly from its container to another
without any contamination, avoiding backflow when stopping the pump as the tube remains pressed by the roller.
The nature of some corrosive substances or other characteristics that prevent the use of conventional pumps
make peristaltic pumps especially useful for transferring or dispensing such substances.
Flow rates are obtained from 0,02 ml/minute up to 6000 ml/minute.
Many different size tubes or hoses made of materials resistant to various substances are available.

4- DESCRIPTION
The D-25Vplus peristaltic pumps in this manual mount the 253-3r head that allows easy access to the tube for
removal when it must be replaced.
To change the tube, the top of the head must be removed. To be able to extract it, the lever (number 1 in the
photo) must always be located to the left of the head. Once located, it must be extracted upwards with the help of
the two retainers located on both sides (number 3 in the photo).
Once the upper part has been extracted, we proceed to place the tube with which we want to work, taking care
that it is centred in the yellow guides located on both sides (number 8 in the photo).
Now we are going to replace the upper part, check that the lever (number 1 in the photo) is located on the left.
Insert the upper part carefully and making sure that the 4 rails (number 7 in the photo) that have the removable
part and the piece in the central part (number 9 in the photo) enter their corresponding guides. Once correctly
oriented, press down until the two parts of the head, the fixed one (number 5 in the photo) and the removable one
(number 6 in the photo) are at the same level and we check that the tube has been well centred, once we reach
this position, we move the lever (number 1 in the photo), from the left to the right, slowly, checking that all the
parts are well aligned.
NEVER CARRY OUT THIS OPERATION WITH THE EQUIPMENT RUNNING.

5 - Fixed part of the head.
The 253-3r head accepts a complementary head, which is placed in front of the already installed head. To install
it, it is necessary to remove the protector 2 to face the complementary head with the axis and insert the two
assembly screws.
With 2 heads it is possible to cancel the typical cadence of the peristaltic flow. To do this, when locating the
complementary head, the rotor rollers must be oriented in opposition to the main head rollers.
Each head will have a flow rate, depending on the diameter of the pipe placed. If they are the same diameter, the
flow rate will double.
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.

6- START UP
INITIAL CONSIDERATION:
For a correct dosing with a Peristaltic Pump with a timer, first you must select the
appropriate tube, both in composition and measurements to carry out the dosing of the
desired volume.
Tests must always be carried out to determine how much volume is dosed per unit of time.
To do this, a series of dosages must be made, and the volume dosed must be checked. If it
is necessary to increase the dosed volume, the dosing time will have to be increased and if
it is necessary to decrease it, it will have to be reduced.
Once this time has been found, we can start working in the mode that best suits us.
6.1- In facilities for processes or assemblies that include a DINKO Pump, there is no must be put into
service before checking that the safety regulations of the European Machinery Directive 2006/42/EC.
6.2-Place the motor rotation direction selector in position “0” (Figure a (3)).
Check the position of the IO selector (Figure b (10)).
Choose the speed using the percentage numeric indicator buttons. With a100% reproducibility speed
range available from 0 to 99% speed maximum with an accuracy of 1% (Figure a (2)).
6.3- Install the selected tube.
During the first few minutes of operation, some of the recently installed tubes suffer an elongation that
alters the distances between the tube and its fixings with the rollers. Readjust the tube in the head to
prevent the rollers from unexpectedly tearing the tube.
Marking the tube with a marker makes it easier to detect a faulty fixing of the tube to its head that will
cause the tube to break by the rollers.
Locate the tubes for loading and unloading the fluid to be pumped.
See instructions in sections 4- Description and 9- Tube Change
6.4- Set the main switch to the OFF position (Figure b (7)).
6.5- Connect the power cable to the rear connector and to the main power. (100-230V 50/60Hz)

8- ACCESSORIES
8.1 Balance for flow and dosage calibration.
Reproducibility 0.01 g. 1000g capacity. Code 1.9812.01
To measure the quantity dosed in the Calibration process of peristaltic pumps, it
is very effective to use a precision balance with digital reading.
If the liquid to be pumped has density "1" there will be no difference between grams and millilitres. Otherwise,
calculate the density by weighing a quantity of the liquid with the help of a 25ml test tube, for example,
previously taring the test tube on the scale.
Divide the weight indicated on the digital readout of the scale in grams by the millilitres contained in the test tube
to obtain the density according to the relationship,
D= M / V.
There is always the option to Calibrate the pump directly based on weight instead of volume.
Characteristics:
♦Single digital reading platter, with highly visible backlit LCD screen.
♦Simple use of great robustness with ABS casing and hermetic anti-humidity membrane keyboard
♦Stainless steel pan, 157x128mm ♦External self-calibration ♦Units of measure: grams,
pounds and ounces
♦Continuous tare up to 1000 g ♦Power supply 230V 50/60Hz ♦Non-slip rubber feet

9- CHANGE OF TUBES
Each pump is supplied with a set of medical/food grade silicone peristaltic tubes according to FDA and USP
standards, autoclavable at 120ºC, with peristaltic use range up to 80ºC and medium duration.
The peristaltic quality of the tubes or rubber consists of their ability to quickly recover their roundness once
the rollers of the peristaltic head of the pump have compressed it to generate the circulation of liquids inside.
In addition, it must offer a minimum mechanical quality to overcome the wear caused by continuous
compression of the rollers without losing its peristaltic capacity.
The pumps use tubes with a calibrated wall thickness of 1,6mm. More thickness will severely damage the motor
shaft and less thickness will prevent peristaltic function and the pump will not pump any liquid.
Thick liquids are best pumped with large tube diameters at low rpm. In the case of external connections, it is
better to use tubes with a larger diameter than the one used in the head. The difference in height between
supply and discharge always influences the performance of the pump and notably in thick liquids.
The pump feed and discharge tubes can be of any wall thickness with an inside diameter as close as possible
to that used in the head or larger, especially on the suction side.
The set of external tubes or connections must be as direct and straight as possible.
There is a range of rubbers that offer different chemical compatibilities with the products to be pumped.
The pump calibration must be updated every time the working conditions of the pump are altered, such as a
change of tube, diameter or type of rubber, distances, new connections, etc.
The standard endowment tubes supplied with the pump are made of medical / food grade silicone according to
FDA and USP standards, sterilizable by autoclave at 120ºC, with a peristaltic range of use up to 80ºC and medium
duration.
Important: Head tubes should be lightly coated with silicone grease to extend life and ease starting at low rpm.
Silicone grease, 50g. Code 8.0030.03
Press OF switch. Extract the tube according to the indications described in the “Description” section.
When the new tube is installed, it should be centred over the rollers to prevent the rotor from pinching it.
Be careful and avoid pinching your fingers. close head
During the first few minutes of operation, some tubes that have just been installed suffer an elongation that alters
the distances between the tube and its fixings with the rollers. Readjust the tube in the head to prevent the rollers
from unexpectedly tearing the tube.
Marking the tube with a marker makes it easier to detect a faulty fixing of the tube to its head that will cause the
tube to break by the rollers.
Because the friction of the tubes with the rollers increases with the diameter of the tubes, the minimum adjustable
speed increases the larger the tube.
It is advisable to use a speed slightly higher than the minimum adjustable speed observed, since the motor may
stop at any moment and cause the regulation circuit to overheat, which could be damaged if it remains in this
situation for a long time.

13-MAINTENANCE – SPARE PARTS
13.1 LUBRICATION
Before any examination or repair of the appliance, it is necessary to disconnect the mains plug.
Any initiative must be carried out by qualified personnel to avoid greater evils.
Entrust your device to a technical service authorized by DINKO Instruments.
The engine and its block do not require greasing, so they don’t have
maintenance.
The rotor bearings are self-lubricating, but it is advisable to lightly lubricate them
with silicone grease ref. 8.0030.03 or similar from time to time next to the rollers
or the head opening lever and its guides, especially if they have been washed.
Remove the head cover and access the rollers (See figure)
The head tube must be replaced periodically in a systematic way to avoid the inconvenience of its breaking
during full operation of the pump.
13.2 TUBES
The head tube must be replaced periodically in a systematic way to avoid the inconvenience of its breaking
during full operation of the pump.
13.3 WASHING
At the end of the use of the pump, it is advisable to purge the contents of the tubes to avoid possible
solidifications that could obstruct their interior, especially in tubes with a small internal diameter, and preferably
pump some inert and compatible liquid to complete the washing. Pay attention to avoid possible splashes
