This concept isn't limited to to pumps either. Having as few different parts as possible reduces your need to carry spares. Any time you can use the same part in two or more places you have built-in redundancy.
Another friend had a 4x4 Mexico desert truck with a trailer. Even though it was vast overkill, he used the same tires on the trailer as the truck. That way he has up to three spares if needed.
redundancy is good, for sure. Our freshwater pump and saltwater pump are different Groco models but both use the same impeller and same motor
That was great because within a few minutes of first using the salt water wash down pump...the motor failed. So, needing wash-down more than fresh water (we can hand pump that), we took the motor from one to the other. Then, later, put the motor back on the fresh water side. Um...I won't tell you what I did, but shortly after that I managed to run us out of fresh water on the tank feeding the pump
and burn up the (hard plastic) impeller on the fresh water pump. So, now we're down to one pump
with some parts on order, oh, yea, and hubby digging through his memory on how to re-wind the armature on the salt water pump motor so we don't have to buy a new one.
