Page 3: 1- General Introduction
1- GENERAL INTRODUCTION Peristaltic pumps pump all kinds of liquid substances without coming into contact with 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. -

Page 5: 4- Description
4- DESCRIPTION The D-25VT peristaltic pumps in this manual mount the 2 or 4-channel MC head that allows the tube holder cartridge to be easily removed for removal when it must be replaced due to breakage or wear. Simply press the release lever to release the cartridge from the head. Each cartridge constitutes 1 dosing channel. - Page 6 4.1.1 How to place and remove the tubes from the head. The head is delivered with the tubes in place and with the tensioner loosened. The first thing to do is adjust the tensioner so that the fluid can flow and that it is not too tight to damage the tube.
- Page 7 Now we can extract the cartridges and thus we can change the tube. We will remove the tube through the open part of the cartridge. Once outside we will put the new tube. To replace the cartridges, we will insert them into the head, first placing the left part in the guide, when we have it in the guide, we will insert the right part until it is anchored, like this with all the cartridges.

5- SPECIFICATIONS 5.1 DIMENSIONS Pump: 340x280x180. Weight 7Kg Operation: between 100 and 240V. 50/60 Hz. Amp.0.5 /1 5.2 FLOW TABLE - Orientative flows for each tube- D25VT Tube inner diameter mm Minimum flow: ml/min Maximum continuous flow ml/min Flows calculated with water under normal conditions without outlet back pressure. Moving the tube clamp lever to its vertical position increases the pressure of the rollers on the tube, which will require two to three times more Torque and shorten the life of the tubes. -

The timer has two programming times t.oFF and t.on indicating the status of the timer contacts. t.oFF will always be the first to count and then t.on will count . N, F modes we can only program the t.oFF , instead in the R mode , we must configure the t.oFF and he t.on .
- Page 13 Turn off the equipment and turn it on again. With the equipment turned on, press ▲ and check the programmed t.oFF time (lower green display), if it needs to be modified, see 7-2 Selection of operation and stop time (page 10). Position the direction of rotation selector in the desired position so that the head rotates clockwise or counterclockwise.
- Page 14 When you want to program a single dosage with a delay; that is, when the timer is activated, it will count the programmed time with the head stopped and at the end of said time the head will start up, it will work until the equipment stops. Programming: Timing mode selector in position I (Figure b (10)).
- Page 15 7.3.c- R mode Asymmetric cyclical mode, in which an operating time and a stop time are programmed to repeat indefinitely. This working mode is used for: When we want to carry out a repetitive dosing of a specific volume, having a stop time between dosing and dosing, to be able to place the rubber in another container to do another dosing.

Page 18: 9- Changing The Tubes
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. -
