advice to pulling out a submersible pump
(OP)
Dear friends,
I dont know if this forum is a right place to ask this question or not?
We have a 100m deep water well.
during the pump installation one of the pipes has broken from the flange weld and the pump (together with 3 pipe) was fallen in the well.
now i need an advice how to pull out the pipes and pump from the well.
dell diameter=10"
pipe size=2"
each pipe spool length=6m
pump weight=400 kg
Thank you.

880 lbs plus 18 meters of pipe is heavy but might be possible.
Is the tip of the pipe accessible or is it leaning against the well liner?

Thank you for your reply.
the wall iner pipe is pvc, the pump and it's pipes are carbon steel and magnetic, but i am not sure to send the magnetic device under the water, because most of them are working by electricity.

Thank you for your reply.
Ca you send me any image of such device.
Thank you

RE: advice to pulling out a submersible pump
Idea is like a mirrored clothespin: Instead of the spring 1 on the outside of the jaws holding a wooden clothespin's jaws shut, spring 1 is on the inside of a hollow pair of steel jaws hold the jaws open. (Spring 2, on the back holds the jaws shut so the assembly can slide down the pipe.)
Two jaws pivoting on one axle is sketched. three (possibly 4) jaws pivoting on 2 axles are better but more complicated. Harder to prototype and build.
put a TV-type camera (similar to a boroscope head) on the jar tip. Lower the assembly with a line (not shown) down near the pipe, and open the jaws with spring 2. (A hard stop couuld also be used.)
When the jaws get engaged on the target, pull line 2 to pull roller 2 back towards the top of the outer pipe. This roller moved and forces jaws 1 and 2 back together 0 clamping the target for retrieval.
