- Page 3 1- GENERAL INTRODUCTION Peristaltic pumps pump all types of liquids without coming into contact with mechanical components, as is the case with other pumps. They are easy to operate and require minimal maintenance. The pumped substance is propelled inside a flexible tube by the vacuum generated by a set of rotors that successively squeeze and release the tube's surface.
- Page 4 3.6- SIGNS AND SYMBOLS Always heed the hazard warning signs and symbols that appear in this manual or on labels attached to the pump body, such as those shown below. SIGNS/SYMBOLS INTERPRETATION-MEANING Avoid contact of fingers with moving parts Danger-Risk-Caution Before opening DISCONNECT Before accessing the inside of the Pump, disconnect the...
- Page 5 4- DESCRIPTION The D-25VT peristaltic pumps in this manual are provided with an easy-load CF-4r head that allows access to the tubing for removal when it needs to be replaced due to wear or for sterilization. Simply pull up on the top of the head to load the tubes. They accept various tube sizes which, combined with speed regulation, provide a wide variety of flows, as can be seen in the flow rate table.
- Page 6 In red we can see the correct position of how the mark on the moving part should look with the head closed. Check, by applying a little pressure, that the moving part is in the lowest possible position. This operation must be performed on both wheels, both on the right side and the left side. Once checked, we can now place the tube inside the head.

- Page 8 6- START-UP INITIAL CONSIDERATION: For correct dosing with a Peristaltic Pump with timer, you must first select the appropriate tube, both in composition and measurements, to perform the dosing of the desired volume. Tests must always be carried out to determine the volume delivered per unit of time. To do this, you need to perform a series of dosages and check the dosed volume.

- Page 11 7-2 Selection of running and stopping time. The timer has 2 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 start. N, F modes we can only program the t.oFF , whereas in R mode, we must configure the t.oFF and he 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 (by pressing the ▲ key on the timer, it 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 dosage with delay , that is, when the timer is activated, it will count the programmed time with the head stopped and when said time ends the head will start working, it will work 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.
- Page 15 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 millilitres.

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. Code 1.0080.14 Straight connector for 9/12 mm inner diameter tubes.
- Page 17 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.
- Page 19 ORDERING INFORMATION Peristaltic pump head CF-4r. For 1.6 mm wall tubing. Model D-25VT. Code: 1.9737.40 11- CHANGING FUSES The fuse box is part of the power supply base located on the rear of the pump. See figure. Main switch Fuse box Power base Pry the fuse box between the center of the fuse box and the top of the power supply base with a screwdriver to remove it.
- Page 20 Before any examination or repair of the appliance, it is necessary to disconnect the power supply. Every initiative must be carried out by qualified personnel to avoid major problems. Entrust your device to a technical service authorized by DINKO Instruments. The engine and its block do not require lubrication so they do not have maintenance.
- Page 21 14- WARRANTY DURATION: The warranty is valid for a period of one year from the date the appliance is put into operation, provided the warranty card is returned to us within eight days of its commissioning. Without this condition, the warranty will not be valid. SCOPE OF WARRANTY: The warranty covers manufacturing and material defects for an average work week of 40 hours.
