Warning! Refers to safety regulations and requires safety measures that protect the operator or
other persons from injury or danger to life.
Caution! Emphasizes what must be done or avoided so that the unit or other property is not
damaged.
Notice Gives recommendations for better handling of the unit during operation or adjustment as
well as for service activities.
The numbers printed in bold in the text refer to the corresponding position numbers in
the illustration on page 7.
•The point emphasizes an instruction
step.
Instruction steps in the illustrations are
indicated with arrows.
When several instruction steps are
indicated in an illustration, the shading of
the arrow has the following meaning:
Black arrow = 1st step
Grey arrow = 2nd step
White arrow = 3rd step

1.3 For Your Safety
For safe and successful operation of the unit, read these instructions completely.
If the instructions are not observed, the manufacturer can assume no responsibility.
Be sure to retain this manual for future reference.
When working with pressurized air, wear protective glasses!
Observe general safety regulations and manufacturer’s instructions for the
handling of chemicals.
If chemical products are not properly handled, damage to health can result!
Request a safety data sheet for the LOCTITE®-adhesive used!
1.4 Field of Application (Intended Usage)
The VoluDrop Dispenser is suitable only for the exact drop application of
LOCTITE UV acrylics up to a viscosity of 15,000 mPas.
It is not suitable to dispense UV acrylics with anaerobic component,
cyanoacrylates, abrasive adhesives and anaerobics.
Only drop dispensing is possible.
Up to a viscosity of 5,000 mPas the dispenser is able to spit adhesives.
Spitting is possible form 3 µl up to 15 µl, non-spitting from 0.8 µl up to 3 µl.
Within a distance of 50 mm a feed motion of the workpiece is not necessary. The
dispenser should be mounted with the dispensing needle downwards.
The dispenser is used as a stationary applicator unit. It is mounted directly at the
dispensing position. The free end of the product feedline is connected to the product
reservoir.
For product reservoirs, 0.5 l and 2 l versions are available.
The control of the dispenser is provided by a control unit of the LOCTITE equipment line.

2 Description
2.1 Theory of Operation
The LOCTITE adhesive is transported through a product feedline to the dispenser by the
dispensing pressure in the product reservoir. This feedline has a PTFE-liner to prevent
curing of adhesives in this area.
When the ejector piston moves back the dispensing chamber will be filled. The adhesive
is spat under high pressure by very fast movement of the piston. During dispensing a
non-return valve prevents back-flow of adhesive to the reservoir.
The amount of product dispensed is controlled by the volume of the dispensing chamber.
Via a stroke adjustment the amount can be limited between 0.8 µl to 15 µl per shot.
As a matter of principle, spitting is possible with each LOCTITE dispensing needle. An
exact spitting is only possible with the conical needles.
Generally, the size of the needle should be adapted to the required amount.
2.2 Operating Elements and Connections
1 Luer-Lock Adapter to mount a dispensing needle.
2 Integrated Non-Return Valve prevents dripping of adhesive due to the
reservoir pressure.
3 Non-Return Valve to prevent back-flow of adhesive to the reservoir during
dispensing.
4 Feedline Connector to connect a feedline (OD 1/4" or 6 mm) to the reservoir.
5 Dispenser
6 Lock Nut to fix the stroke adjustment knob.
7 Stroke Adjustment Knob to reduce stroke and therewith the dispensed
quantity.
8 Compressed Air Connector, to connect pneumatic tube, OD see section 3.

4 Installation
–Keep the pressure hose as short as possible. Short switch-on and switch-off times for
the dispenser are within reach.
–Keep product feedlines as short as possible. The shorter the feedline the smaller the
specific resistance and the lower the dispensing pressure can be.
–Avoid kinking of feedlines and pressure hoses.
–Typically, the pressure hose and product feedline should not be longer than 2 m.
–Do not use inflexible hoses and feedlines, so that unnecessary loads on the fittings will
be avoided.
–Keep all fittings tight.
–No direct sunlight; no UV light!

4.3 Selection of the Required Dispensing Needle
For each product and corresponding application of the
dispenser, various dispensing
needle types and sizes are available:
–Conical dispensing needles of polyethylene for viscous products and large
dispensed quantities.
–Stainless steel needles for thin fluids and UV curing products (especially suitable
for spot applications).
–Flexible dispensing needles of polypropylene (especially for dispensing on
damageable surfaces).
–PTFE-lined stainless steel needles (especially for fast curing products).
As a matter of principle, spitting is possible with each LOCTITE dispensing needle.
An exact spitting is only possible with the conical dispensing needles.
With same dispensing quantity certain correlation determines the selection of the
needle.
The table below shows these correlation.
