Theory of Operations

The EQ PU20 Digital Peristaltic Dispenser transfers low viscosity liquids by pressure displacement applied by a turning rotor against a tube carrying the material. Usually these pumps are chosen because the liquids are hazardous or difficult to work with and it is advisable to limit operator contact. Another reason is that peristaltic pumps are air free.
Dispense outputs can be timed from 0.01 – 99.99 seconds with flow speeds from 0.01-6 ml/min using PTFE tubing. The pump is bi-directional allowing suck-back after dispense to prevent dripping of the fluid. When dispensing UV adhesives use only black tubing. This avoids curing of the adhesive in the tube.
The amount of product dispensed is controlled by:
Dispensing time
Feedline size
Motor speed
Needle size
Various sizes of PTFE tubes, the corresponding applicator nozzles and dispensing needles are available, see section 5.1

Mounting the feedline to the dispenser

Selector Chart Feedline

1. Lift Guide Lock 1 and release tube guide 10.

2. Lubricate the tubing and roller with Silicon Grease， HENKEL IDH# 88722。(Not included in package，need purchase separately).

3. Put the tube into the groove of the left tube holder.

4. Place the tube directly on the rollers.

5. Put the tube into the groove of the right tube holder.

6. Press the white guide plate of tube holder on both sides carefully against tube and fix it with the locking knob.
   Note; Pay attention that the tube is placed directly on the roller..

7. Slowly close the tube guide 10 and apply downward thumb pressure whilst turning the Pump Head 12 manually
   Notice!
   If the tube guide is tightened without turning the rotor, the shape of the rotor rolls will be impressed and the tube will not be inserted evenly. Always turn the rotor after closing the tube guide and press the tube guide 10 against the rotor.

8. Secure the Tube Guide 10 by using the spring loaded Guide lock 1

9. Set unit to manual Mode (section 5.4.2) and press start to check rotation of Pump Head 12

Tube Guide adjustment

If a large diameter feedline is used and the Pump head 12 does not rotate then follow the procedure below:

1. Lift Guide Lock 1.
2. Unscrew the bigger lock grip from the smaller one.
3. Turn the screw counterclockwise one revolution.
4. Assemble both lock parts.
5. Close the Tube Guides 1 as described in Section 5.1 and start dispensing.

Best practice guidelines

• Keep the product feedlines as short as possible. Typically, the product feedline should not be longer than 2 m.
• Avoid kinking of the feedlines
• Ensure all fittings are secure and tight

Mounting the Feedline to the Applicator

1. Pull the tube through the applicator and the applicator tip adapter.
2. Mount the applicator tip adapter.

Mounting the Feedline to the Product Bottle

Dispensing Cyanoacrylate:

• Cut the nozzle of the bottle only as much as it is necessary to insert the tube.
  Notice!
  It is necessary to minimize moisture access to the bottle that causes curing of the CA.

Dispensing Anaerobic:

• Unscrew the dispensing cap.
• Cut the tube in the way described in the right graphic.
• Insert the tube into the bottle.

Cleaning and Changing

Clean the roller with a dust free tissue or towel.
Lubricate the rollers of the pump head WITH A Silicone grease once or twice a week. Lubrication will help prolong tube life.
Lifetime of the Feedline:
The PTFE tube should be replaced periodically. The lifetime of the tube will vary depending of the rotation speed, frequency of use, etc. The user should determine how often to replace the tube according to their need.
At adjustments „Speed 5“ and „CCW“ (pump head turns right) the lifetime of the PTFE feedline >200 h. If the velocity will be increased the lifetime is proportionally reduced and vice versa.

When dispensing, Cyanoacrylates apply a small amount of silicon grease to the applicator tip adapter 17 to prevent needle bonding.
