Well pumps and SWs revisited [RE-wrenches]

[ASAP POWER!]

Wow!  Ray, does your pile include the SW4048/24 as well with its
respective/relative surge capacity?

PD
ASAP POWER!

NO one has mentioned in this thread that the SW5548 is terrible at surges.
I've been disappointed that it trips its over current switch when a lowly
DR2424 can hang in there.( on air compressors for example) This has been
covered on the list before.
I've run a 2 hp pump with a T240 and DR3624 before in an emergency. It
started and stopped flawlessly even at 350 ft and 40 psi in the pressure
tank.
I  put the SW5548 in the same pile as the PS series ,XTR sun tie etc. I
won't sell em!
