Hi everyone
I have a failed (seized and leaking) 3 phase circulating pump. A direct replacement is well into 4 figures
I have a pump that will fit, and has enough flow to do the job, but it's single phase.
The supply to the pump is via a contactor, and there is no neutral.
Is there any way to derive the necessary 240v single phase from the 3 available phases?.
I know I could do it safely electronically, or even a transformer from the 400v across 2 phases down to 240, but would it be permitted?
Re-cabling it is possible, but a real pain I'd like to avoid as it's done in pyro, and it's several layers deep in the cable tray. Also, I'd like the option of putting the right pump back at some future point.
Any suggestions welcome.
