The nameplate brand isn't nearly as important as the pump and motor.
I see Cat and that it's belt driven and that's about as good as it gets.
We've had a direct drive Cat for probably 6-7 years now, I just replaced the pump
this year and will rebuild the old for a spare. Keep them oiled and watered and they're
pretty much bullet proof.
Make sure that wherever you mount it you can access it for A: Hose Leaks (guaranteed at
some point) and B: yearly oil changes.
The pressure sensing on/off switches aren't great for pump life. Put an air foot
switch in line, keep electricity away from water.
