What I didn’t make clear in previous text was that the 3x12.00$ pump relays effectively replaces the expensive and unreliable frigoboat pump controller. So a good, reliable and inexpensive option to have on hand.

On this issue.
Had a long conversation with Rob at Costal CLimate.  As usual, a very knowledgeable guy.
His thoughts.  Flojets are super reliable, AS long as they aren't drawing a lot of current, i.e. sucking hard against resistance, or pushing against resistance.

Often a change in pitch denotes strain, I’ve definitely been guilty of letting that go… and with in a short time, at least with my experience, the pump then fails, and off to either the junk yard, or later a take apart.  So now I’ll check amp meter if >1.2 amps check the flow and make sure the water paths are unobstructed. 

Also… they tell me the frigoboat pump controller is very unreliable, as we've noted on the forum.


and 2 24 v pumps as it would have to wired to the 24v bus.


Just some thoughts…

Thanks Jamie. Yes I have been following this thread about alternatives and wait in anticipation! I have not heard about anyone successfully refurbishing the flowjet.
 
Cheers,

Paul, as you have probably read in another long thread about this very subject, you are not alone. Several of us are trying to come with a viable solution that we can all use to deal with these pumps.

Stay tuned if you can wait a bit. I have ordered some parts to construct a variable-speed drive brush-less motor as conceived by Oliver on Vela Nautica - waiting for the parts now. I have been in contact directly with him.

I will start a new thread if I am successful.
