4- DESCRIPTION

The D-25VXi peristaltic pump is provided with 50-2r heads that allow access to the tube for extraction when

it must be replaced due to wear or for sterilization. It will suffice to remove the cover by removing the three

fastening screws.

They admit different tube sizes that, combined with the electronic speed regulation, give a great variety of

flows, as can be seen in the table of indicative flows in the manual.

On the back they incorporate a connector for pedal (foot switch) and remote-control operation, power socket

with fuse box and general ON/OFF switch.

On the front there are switches to change the direction of flow and stop as well as potentiometers for

percentage speed regulation, per channel.

Pumps are manufactured with the number of heads requested or with other heads with higher performance.

5- START UP

Assemble the chosen tube in each head. See “Changing tubes”.

Make sure that the mains voltage is between 100 and 230 V.

Connect the power cable to the rear plug and to the network.

In facilities for processes or assemblies that include a DINKO Pump, they must not enter into service

before checking that the safety standards of the European Machinery Directive 2006/42/EC are met.

Press the ON switch.

The speed regulation knob is a potentiometer with a numerical counter of turns from 1 to 10.

The dial is numbered from 1 to 10 for each turn, so the regulation is from 0 -100%, in increments of 1% and

repeatability of 100%.

Each head has its speed regulator and flow direction change and stop switch.

If you want a spindle not to work, act on the individual stop and flow direction switch instead of placing the

regulator at 0% to avoid any small rotation of the motor due to residual currents.

6- CHANGE OF TUBES

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

“Heads” section.

When removing the tube from the heads, do it together with its fixing terminals.

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

Take advantage of the slow rotation of the rotor to insert the new tube. This avoids forcing the axis when

trying to place the tube with the rotor stopped.

Be careful not to pinch your fingers. Put the lid back on.

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 elongation or insufficient fixation of the tube to

the head, it is useful to properly mark the tube with a marker.

A tube set is supplied with each pump.

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 supplied silicone tubes are medical / food grade according to FDA and USP standards, sterilizable by

autoclave at 120ºC, with a peristaltic range of use up to 80ºC and medium duration.

AVAILABLE MATERIALS

The most mechanically resistant tubes are PHARMA, TYGON A-60, TYGON A-60-G and SILICONE with

medium duration, but the durability also depends to a large extent on the chemical nature of the pumped

liquid, the pressure, existing temperature and naturally of engine revolutions.

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

diameter tubing and decreased tubing life.

PHARMA Autoclavable multiple times.

ETO and Gamma sterilizable .

Medical-food grade, class VI USP, 21CFR 177.2600 and FDA. Not hemolytic.

8- MAINTENANCE-SPARE PARTS

Before proceeding with any examination or repair of the device, disconnect the power supply.

Any initiative must be carried out by qualified personnel to avoid greater evils.

Entrust your device to a technical service authorized by DINKO Instruments.

LUBRICATED

The engine and its block do not require greasing, so they are maintenance-free.

The rotor bearings are self-lubricating, but it is advisable to lightly lubricate them together with the rollers

with silicone grease ref. 8.0030.03 or similar from time to time, especially if they have been washed.

PIPES

The head tube must be replaced periodically in a systematic way to avoid the inconvenience of its

breaking during full operation of the pump.

WASHED

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.

9- ACCESSORIES

9.1 Balance for flow and dosage calibration.

Reproducibility 0.1 g. 600g capacity. Code 1.9812.02

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 millilitre’s.

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 millilitre’s 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 600 g ♦ Power supply 230V 50/60Hz ♦ Non-slip rubber feet

♦ Working temperature: from +5ºC to +40ºC. Maximum use humidity, 85% RH
