Want to know what I did while I was out of town last week? Here’s a (very unflattering) shot of me standing next to a 2200Hp slurry pump. (No, I’m not that fat, it’s the way that damned safety vest hangs with my computer bag hanging off my shoulder.)
There were four of those at the site, all run on large variable-speed drives. I used to apply and sell those drives. Now I specify them, and then make sure they’re installed properly.
