Q
Will this pump work as a replacement for the Bak Pak 2 skimmer?
Didn't know if it would fit in the inlet and had a hole for the airline like the one that comes standard with the Bak Pak 2

A
The Bak Pak 2 now use custom Accela pumps. A standard Replacement pumps available and the item number is CR1135. A Cobalt pump will not work without modification.

“Great little pump”
5.0

Pretty quiet pump. I used the suction cups to keep it in place. I have a couple of these and they do a great job for the amount of flow they push out and work well with valves for adjusting flow. Perfect for GFO or Carbon, but I may consider a bigger pump for biopellets.
