DESCRIPTION
Unitized instruments contains a peristaltic pump, speed control and on-of switch for each head pump in a single case.
The peristaltic pumps D-25VXi has heads that facilitates the extraction of the tube when it should substitute or for
sterilisation. In the pumps with 50-2r head type retires the cover extracting the three screws. The head pump CF-3r and CF-
4r is for easy change tube
Each pump admits four or six tube sizes giving the interval flows ranges in the table.
Pumps regulated for sign 0-10V incorporate their connector.
Other multi-heads pumps are available on demand.

Remove rotor.
◊Open protection lid and remove pump head hoses.
◊Open flexible black lid located on the rotor center.
◊With a Phillips screwdriver to remove the central screw positioning.
◊Pull the rotor hub off its axis.
◊Between the hub and the shaft is a split collet. If the collet is retained by the shaft, pull it off, loosening, if necessary, using
light strokes. Do no t try to remove it by prying with a screwdriver. If the collet is retained within the bucket, remove, if
necessary, slightly loosen the screw reinserting central locating and tapping the screw head.
Rotor replacement.

◊Reassemble the split collet on the shaft, rotating it until it is fully inserted. Fit the body of the
rotor drive shaft as a unit.
◊Open the flexible black cover of the center rotor. With a Phillips screwdriver to tighten the
screw positioning a pair of 3 Nm to prevent the collet slipping during work. If the assembly
is correct, the guide rollers of the hose should be aligned with the outer surface of the track.
Close the flexible lid rotor.
◊Close the cover and make sure the rotor is separated from it, watching the first rotation of the rotor.
Placing the tubes (hoses )
The 5000 pump heads are factory set to accommodate tubes from 1.6 mm wall. Pumping performance may be adversely
affected if the tubes are not used right.
◊Check hose length 225 mm. to be placed inside the head. Please
note, if you put more than 225 mm can be seen shortened tube life.
◊Open the bottom clamp (spring) and put the hose to the first mark
of 225 mm. aligned with the inside of the bracket that has the dock.
Loosen the clamp.
◊Disengage the rotor clutch fully depressed the yellow button on the side of the rotor
hub and rotor turning the hub a few degrees, while maintaining the button. Now the
rotor can give a complete revolution independently of the gearbox and engine.
If the clutch re-engages before the hose is fully assembled, press the button again and
turn the rotor a few degrees.
◊Place the tubing around the track head, turning the rotor properly. Make sure the hose is not twisted or pinched between
the guide rollers and track. Check that the second mark of the 225 mm. is located along the inner edge of the upper
clamp.
◊Open the upper hose clamp with spring and place the hose, making sure the hose does not twist and is supported
centrally between the guide rollers of the hose. Loosen the clamp
◊Hose clamps, with spring, holding the hose must be strong enough to keep it from
Moving in or out of the pump head, but should not be tightened too much or choke the
passage of fluid. The clamps have a yellow slide that can be placed in two
positions
while the clamps are open. The external position allows tightly hold the hose clamps,
while the inner position leaves him weaker . Adjust the sliders to prevent tube
movement during a test a few turns the rotor.
◊Close the cover by pushing it fully until the latch engages
◊Remember that it is appropriate, after 30 minutes of operation, tighten the hose back,
which can lengthen as it accommodates.
Tighten the hose so that the 225 mm. hose are located between the parts of the hose
clamp that carry spring.
PREVIOUS OPERATING
1. - Select the tube diameter. Remove the plastic cover of the pump head. Installing the tube with their terminals of
fixation. When you settle the new tube, should remain centred on the rollers in order to avoid the rotor to pinch the tube.
Place the cover again. With each pump the sizes of tube are giving. The feeding and discharge tubes could have any
thickness of wall. But the tube that settles in the pump head should have 1.6 mm calibrated thickness of wall, with the
exception of pump head 1500 pump which uses tube 2.4 mm wall thickness.
2. - Insert feeding and discharge tubes in the terminals of the pump head.
Because the friction of the tubes with the rollers increases with the tube diameter, the adjustable minimum speed increases
as much as big is the tube.

5
Starting from the tube of 4,8 mm the necessary minimum speed is the following one: Tube 4,8 mm / 5%. Tube 6,4 mm/10%.
tube 8 mm/15%. It is convenient to lubricate the tubes lightly with silicone grease to use smaller speed and increase the life
tube.
It is not convenient to use very smaller speed although the motor starts up since in any moment it can stop and to cause a
excessive heating of the regulation circuit that could be damaged if it remains in this situation for a lot of time.
When you use two CF pump head simultaneously, the inside tube diameter could be limited up to 4.8 mm. , especially with t
high hardness tubes
Consult the table of dosages. Install the appropriate tube (see maintenance section).
Put ON the pump using the power switch located at the rear panel.

PROGRAMMING OF THE SCALE( Range).
Push simultaneously SCALE and SET keys for enter to a programming screen in which you can select the scale and the
decimal comma.
If the first scale indicator has intermittence, indicates that it can modify. To select another scale (hours, minutes, seconds) it
is necessary to use the keys↑↓ and next with the key →the range is selected (units, tenth, hundredth). With F on screen
you can program the scale for the time of operation. Pulsing ESCALE appears L on screen and you will be able to program
the scale of the stop time.
To leave programming and to memorize, to pulse SET.
PROGRAMMING OF OPERATION AND REST TIMES
When pulsing ESCALE and SET keys simultaneously, we will be able to modify the value of the times. If the first digit this in
intermittence, indicates that it can modify. For selecting another digit it is necessary to use the keys with the indication →
and next to increase or to decrement with the keys↑↓.
With F on screen the time of operation can be programmed. Pulsing TIME you have on screen L and will be able to program
the rest period. To leave programming and to memorize data to push SET key.
MODE OF OPERATION
ASYMMETRIC OVERTURNED CYCLE
The apparatus, begins the first time activating the exit, when connecting the outburst contact or, this being connected when
giving tension.
When reaching the scheduled value (Ta) the exit is disabled and the apparatus begins the second time. When it reaches the
scheduled value (Tb) active the exit and the cycle begins again. If the operation is carried out with memory, when failing
tension the cycle it continued from the position in that the tension lack took place.
CHANGE TUBES
Press OF switch.
Pump head 50: remove the three screws. (page 2)
Pump head 1500: remove the two screws (page 3)
To take out the tube together with their terminals of fixation.
The new tube should be centered on the rollers to avoid that the rotor breaks it.
To take advantage of the slow turn of the rotor to introduce the new tube. It is avoided this way to force the motor-axis when
one tries to place the tube with the stopped rotor. Be careful not to pinch your fingers.
In general, new tubes can be stretched for the first 30 minutes of operation. If this occurs, tighten again to avoid
unexpected breakage. In order to detect the elongation or insufficient attachment of the tube to the pump head it is
useful to mark the tube with a pen.

Before proceeding to any exam or repair it is necessary to disconnect of the mains.
All initiative should be made by qualified personnel to avoid bigger wrongs.
Trust their apparatus to a technical service authorized by DINKO Instruments.
The motor and block of the dispenser pump don't require lubrication for what they don't have maintenance. It is convenient
to lubricate the rollers lightly with silicone grease.
The tubes should be replaced periodically to avoid the break.
