Page 3: 1- General Introduction
1- 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 propelled into an elastic tube by the vacuum generated by rotors that successively press and release the surface of the tube. -
Page 4: 3- Reception
3- RECEPTION To ensure proper reception and use of the device, and user safety, we recommend reading this manual carefully before unpacking the device and subsequent use, especially the following points: 3.1- THE MANUAL This manual must be kept at all times within reach of the user of the equipment. 3.2- UNPACKING Carefully unpack the appliance, checking that the contents match the list of packaging. -
Page 5: 4- Description
4- DESCRIPTION The D-25VT peristaltic pumps in this manual are fitted with the CFV-4r head which allows easy access to the tube for removal when it needs to be replaced. The head supports various tube sizes which, combined with speed regulation, gives a wide variety of flows, as can be seen in the flow rate guide table. -
Page 6: Front Panel
CFV-4r multiple coupling head The pump mounts one head as shown above and can mount up to a total of four heads in its place. Two heads are shown attached below. The pump heads of a coupled assembly must be assembled and configured at the factory as such. Remove the head and send it to the factory to configure the required head assembly with a maximum of 4 heads. -

- Page 11 7-2 Selection of running and stopping time. The timer has 2 programming times t.oFF and t.on that indicate the status of the timer contacts. t.oFF will always be the first to count and then t.on will start . N, F modes we can only program the t.oFF, however in R mode , we must configure the t.oFF and the t.on.
- Page 12 7.3 Modes of use The pump has a timing mode selector with two positions, O and I, on the back . (Figure b (10)). In position O , when the timer is started (pressing the ▲ key on the timer will start counting the programmed times), the head will run for the time programmed as t.oFF.
- Page 13 When you want to program a single delayed dosage; that is, when the timer is activated, it will count the programmed time with the head stopped, and when that time is up, the head will start working until the equipment is stopped. Programming: Timing mode selector in position I (figure b (10)).
- Page 14 7.3.c- R Mode Asymmetric cyclic mode, in which an operating time and a stopping time are programmed to be repeated indefinitely. This working mode is used for: When we want to perform repetitive dosing of a specific volume, with a pause between each dosing to transfer the rubber to another container for another dosing.

8- ACCESSORIES 8.1 Scales for flow and dosage calibration To measure the dosed quantity in the calibration process of peristaltic pumps, it is very effective to use a precision scale with digital reading. If the liquid to be pumped has a density of "1," there will be no difference between grams and milliliters. - Page 16 CONNECTORS FOR PERISTALTIC TUBES 8.5 Straight connectors for splicing / equal ends, polypropylene Straight connector for 1.6 mm inner diameter tubes. Code 1.0080.15 Straight connector for 3.2 mm inner diameter tubes. Code 1.0080.18 Straight connector for 4.8 mm inner diameter tubes. Code 1.0080.05 Straight connector for 6.4/8 mm inner diameter tubes.

Page 17: 9- Changing Tube
9- CHANGING TUBE Each pump is supplied with a set of medical/food grade silicone peristaltic tubing that meets FDA and USP standards, autoclavable at 120°C, with a peristaltic usage range of up to 80°C and medium life. The peristaltic quality of the tubes or rubbers consists of their ability to quickly recover their roundness once the rollers of the peristaltic head of the pump have compressed them to generate the circulation of liquids inside. - Page 18 9.1 AVAILABLE TUBES PHARMA Autoclavable multiple times. Sterilizable by ETO and Gamma . Medical-food grade, class VI USP, 21CFR 177.2600 and FDA. Non-hemolytic. Excellent resistance to chemicals. ISO 10993. Low permeability and good abrasion resistance. Long duration. Use temperature, -51ºC to 132ºC Beige color.
