Anyone tried converting a submersible pump to an inline?

[Szech]

I bought a submersible Rule24 bilge pump. I read that inline pumps work better, and I don't have much space in my case for a reservoir anyway. Well, I took the blue intake filter off, and sized out the intake port. I lathed a barbed hose attachment that fits in the port within 0.002". I plan on epoxying it in place, to make it an inline pump, but I was wondering if anyone did this before. If so, is there anything I should know beforehand? Any suggestions or warnings?

Thanks!

My submersible has threaded ports so it can be used as an inline also. I think before you use it in your case, you should give it an extensive tryout. I don't know how well epoxy will hold up given the vibrations of the pump. Perhaps you might want to consider threading the intake port and using a threaded barb. I think you'll get a much better seal.

HHHHMMMMMMmmmm... Good point

I broke in my pump at 12VDC, and I have it wired for 5VDC, and in both instances, there minimal vibrations. But I think threading the intake would be a good idea regardless. Dang... now I have to machine another one =P. Oh well. I had to anyway for my water block.

I have no idea about the pump you are using but one thing to consider is that some (not all) submersible pumps are required to be under water for proper cooling. Check and see that it doesn't run to hot, if it dies it may take your cpu along with it. The pumps built for either inline or submersible don't have this cooling requirement.

Yeah, I converted a submersible magdrive pump to inline. I drilled a hole in a pvc cap and screwed an NPT brass nipple into it. I removed the pump filter and its cover, and epoxied the turbine cover to the body of the pump. I then epoxed the pvc cap over the pump inlet. It's cooler, more compact, and quiet.
