Has anyone found a way to prevent West pumps from failing to pump after
being stored for a while?

Experienced epoxy users will keep a spare set of pumps put away for just
that happenstance. It's just the nature of the beast and it really doesn't
matter which brand of epoxy you use. Another option is to use an epoxy pump
such as the Sticky Stuff Dispenser (see

System Three recommended using one of those human solvents such as MEK.
I've had fair luck just heating the pump with a hot air gun. It's the same
crystallization you see in the resin, I think. Keeps the ball valves from
seating.

Another little trick is to clean them with DENATURED ALCOHOL then warm soapy
water. Rinse well with water, then the alcohol for a fast dry.

I clean mine every now and then. Use acetone or other nasty solvent for the
resin pump and warm water for the hardener pump.
