power supply for flojet pumps

[Bridgewater Brewer]

good morning all

i wondered if i could pick the collective brain?

i bought two reconditioned flojet 12v 7a ( I'm assuming Amp here) pumps off e-bay.

with great excitement last weekend i connected the correct fittings and then wired the pump up to the tattoo controller i currently use with solar pumps (1 amp) only for nothing at all to happen.

I'm assuming I need to supply 12v 7 amp but it seems a difficult spec to buy for, theres lots of 12v 6 amp etc out there .

I'd welcome advice and suggestions here.

happy brewing

there are plenty about on ebay

and you can control the power with something like this

the amperage is what your pump needs so any power supply 12V exceeding 7A will suffice

Hi,
power supplies are usually only about 80% efficient.
I would probably consider a power supply of at least 10A per pump.
If you use a 10A power supply, you will only be able to run one pump at a time.
Either two 10A power supplies or one around 20A

Thank you so much. Ordered and I can't wait for Christmas so I can start brewing again.
