Is this a good pump

post #1 of 20
Thread Starter 
is this a good pump http://www.koolance.com/shop/product...roducts_id=493

Some of the guys said to try the swiftech pumps like the MCP655
but for 1/2 barb pumps I think the koolance is better


What do you think?

Right now I have a hydor L35 which has shi..y head pressure....If I push it any hard it's going to blow captain..

its the same as the DangerDen D5 and the Swiftech MCP655, Its a really good pump although the DD and Swiftech ones are alot cheaper. The Laing DDC-2 w/Petras top is also a better pump

Same thing but cheaper here:
http://www.sidewindercomputers.com/swmc12vdcpuw.html

I have one of each type, variable vs. non-variable, both perform the same and like Ira-K noted everyone runs them at max anyway. I also flowrate tested them both and they are the same.

Wouldn't waste my money getting a variable again unless you were retrofitting a cheap TT loop or something where you really needed the slower speed just to be safe.

Get a dedicated PSU that puts out 24v.
