Hell, the pump in mine is at least 15 years old and is used regularly. I keep a 64oz container on my slop sink and a gallon container to refill it once the level drops to the point where the pump won't pick it up.
I have the same issues with the pumice variety. I ordered a gallon of the "smooth" fast orange by accident and found the pump lasts much longer without the pumice, and still cleans pretty good.
That cleaner is good. Very much like the original Gojo. The old push button wall dispenser was great. Then their bean counters eliminated the follower disc in the can, so when people complained the pumps didn't work right anymore, they discontinued the pumps, too. Geniuses...
