While making my model I was asked if it would have a bilge pump in case of accidents. I thought this would be a great idea, so off I went hunting for a stl file on the internet - I found this one http://www.thingiverse.com/thing:4839
after printing this using thick walls I found the impellor too big, no problem, another printed slightly smaller.
this was then assembled using a tiny drone motor. upon testing it proved to work well, and when approximately measured produced a flow rate of about 1.5 litres a minute.

Nice bit of kit Grendel, ideal for those bow ploughing moments....... ok2

That's not a bilge pump, more of a fire hydrant! :-))
-
That looks quite powerful ... would it work as a small bow thruster?
-
I guess it would, but its not really designed with that in mind, it doesnt perform well in reverse

t doesnt perform well in reverse
[/size]Surely,that is a good thing in a bilge pump. O0

They are small enough that you could do two. one for each side maybe.
I am going to try and print a couple and experiment a bit.

just remember you may have to reprint the impellers a fraction smaller, on mine they were about 1mm too big, but then I thickened the walls.
I am currently designing a working anchor winch using a set of gear components I bought several years back, and a cd drawer operating motor, from an old pc CD drive
