The DotMaker™ 2000PD is a positive displacement
dispensing gun for making repeatable deposits of
low to medium viscosity materials.

The position of a volume control knob regulates the
trigger stroke and, in turn, controls the volume
displaced by the internal pump. Squeezing the
trigger displaces the shot and releasing the trigger
charges the chamber.

Follow this step-by-step guide to begin using
your new DotMaker™ 2000PD.

The unique DotMaker™ simplifies

application of low to medium

viscosity fluids.

It is very easy to use and less

fatiguing than other manual

applicators.

Fill level

Filling the barrel reservoir

➀ Install an orange tip cap (#5113).
➁ Load the fluid into the barrel, filling to the

recommended level (see chart).

➂ Insert a SmoothFlow

NOTE: For high volume applications, consider
prefilled reservoirs from fluid packagers.

NOTE: The 2000PD performs best with fluids that pour and thixotropic
materials which will move with pressure of 15 psi or less. Do not use high
viscosity materials such as RTV silicone and heavy grease. Contact EFD
for recommendations.

Setup

NOTE: Prime the 2000PD at the lowest possible volume

setting to minimize waste during final volume adjustments.

➀ Loosen the volume control knob. Pull the trigger in while

sliding the knob to the #1 position; then tighten the knob.

➁ Remove the orange tip cap from the end of the barrel

reservoir.

➂ Look into the inlet port and align the barrel reservoir with

the inlet luer lock adapter. Press the reservoir in and twist
to the right to secure.

CAUTION: Use light pressure to secure the reservoir.

Be careful not to overtighten.

➃ Remove the tip cap from the outlet end of the 2000PD and

install a dispensing tip. Use a small diameter tip for thin
fluids or a larger one for thicker materials.

Priming the 2000PD

➀ Place the dispensing tip on the test paper and

squeeze the trigger repeatedly (about 20 times) until
fluid begins to dispense.

➁ With thicker material, it may help to apply light

pressure on the piston while squeezing the trigger.
Continue to dispense until fluid flows free of air.

Operating the 2000PD

NOTE:

chamber to refill between deposits. Thicker materials
require more time (1 to 2 seconds). When deposits
begin to decrease from shot to shot, it is an indica­tion that more time is required between shots.

➀ The position of the volume control knob determines

the deposit volume. Position the knob near #1 for low
volume and toward #5 for higher output.

Sufficient time must be allowed for the

➁ To adjust the volume control knob, place the dis-

pensing tip on the test paper. Squeeze and hold the
trigger in (some material will dispense). Loosen the
knob and slide it to the desired position; then tighten
the knob and release the trigger.

For best results, hold the dispensing tip at a 45°
angle and in contact with the work surface. Use
the test sheet to practice.

Recommendations

• The DotMaker™ has Viton® seals which work well with most fluids. If your
fluid reacts with Viton®, order pump assembly #2000EPR with ethylene
propylene seals.

• Do not use the DotMaker™ with cyanoacrylate instant-cure adhesives. Contact
EFD for recommendations.

• Anaerobic sealants and thread-locking materials can be dispensed but should
be purged at the end of the day to avoid curing inside the pump.

• UV-cure adhesives work best with the EPR pump assembly #2000EPR.

• Certain high viscosity materials can be dispensed; however, they require more

time to fill the chamber between shots.

Contact EFD if you have questions or need us
to evaluate a material: 800-556-3484.

Purging

To perform a simple purge procedure, remove tip and
install a reservoir filled with an appropriate cleaning
solution. Set the volume control knob to #5 and operate
the trigger until all the solution has been dispensed through
the gun. Repeat if necessary.

Pump Replacement

Remove the fluid reservoir.

➁ Remove the dispensing tip.
➂ Set volume control knob to #5.
