Non controllable pumps for my 50g tank

[Jorsan]

I would like to add strong water movement to my new tank that is a 31"x 19"x 19" (about 50g). Not interested in controllable pumps, just want the tunze quality in an "always on at 100%" power. This will be a SPS sandless tank.
Your input will be apreciated, thanks in advance

I think 2 6045 is the best way to go. 3 6020's could also be an interesting set up as they are small and easy to conceal.

rvitko,
I've been using this pumps for more than a year and Im very happy with them. Lately found that in both pumps I have the disk for drive broken (part 6025.740). Where can I buy this part?. Also need one protecting grating (6025.200 as per the manual).
Finally how can I regulate the flow?, I allways thought that this pump has the same speed but in the manual say that goes from 1.500 to 4.500 l/h, how can I regulate the flow speed?.
thanks in avdance

You can order any spare parts on Tunze.com. The manual covers multiple models and only the 6045 has a mechanical flow adjustment. On the bottom of the propeller housing there is a blue knob that you slide in and out to adjust the flow.
