Hydraulic Retrieval Tool
15
12. Set the pump to “install” and pump until the connecting rod is fully extended. Continue to pump until
the pressure inside the retriever is a minimum of 50 bars and close the head valve watching the
pressure gauge on the pump.
13. Check that the washer at the end of the connecting rod is in place.
14. Pull back the hammer nut and inspect the O-ring at the end of the retriever. Make sure o- ring is
installed. If this is missing; install new O-ring
15. With the head valve closed, release pressure from the pump, untighten the quick coupling safety
nuts and disconnect the hoses.
16. Hold the retrieval tool so the connecting rod faces the service valve. Put the connecting rod through
the service valve, and mate the threads on the rod and the plug. Screw the rod into the plug by
rotating the retriever. Screw until the rotation stops. Do not tighten.
17. Connect the hoses from the pump, tighten safety nuts, and set the pump to “retrieve”. Open the
head valve. Hold the retrieval tool hammer nut away from the service valve threads. Pump in
“retrieve” mode until the retrieval tool is pulled towards the service valve. Pump to approx. 20-50 bar
and visually ensure that the two surfaces retriever / valve mate correctly.
18. Connect the hammer nut to the service valve, and screw until it stops. Then tighten the hammer nut
by use of the plastic or brass spark proof hammer.
19. Set pump to “Install” and pump until the pressure in the retriever is at least 100 bars higher than the
pressure inside the pipeline (confirm line pressure with the control room). If it is difficult to determine
the exact pipeline pressure, the pressure on the pump should be increased to an even higher level.
