tunze pump

[rysher]

i got an extra tunze pump that's for the osmolator.
what voltage do i run this, 12 volts dc? will cellphone chargers work?
where's the polarity on this thing?

 

[rysher]

it is Pump 5000.02

9-12V DC, it also needs a minimum of 1200mA, any power supply that has this rating will work.

 

[rysher]

Roger, which one is positive (+) and which is negative (-), the blue or the brown wire?

 

[rvitko]

It makes no difference, while it does change the rotation direction, this pump design pumps the same volume regardless of polarity.
