Unscrew each nozzle, there is a check
valve ball and spring underneath. I soaked them in acetone and
replaced. Then, after reassembly I pumped acetone thru the pump (got out
some sticky black stuff). Finally I replaced the reservoirs. Works
great now. Don’t forget to weigh a couple of pumps to make sure it
is dispensing the correct ratio. Throw this initial test batch away in
case it is contaminated with acetone. I don’t think acetone will
affect the reservoirs, unless they have changed the material.

Dispenser Cleaning
Hello, everyone. I bought a used epoxy pump a few
years ago and now I am ready to start using it. I got new reservoirs for
the epoxy and hardener and I have cleaned the outside with denatured
alcohol. Is there anything else I need to clean? How can I ensure
everything is clean to put new epoxy into it? I appreciate any advice!
