2.1 Hydraulic Retriever
The Double Acting Hydraulic Retriever is a tool designed for servicing all kinds of equipment that can
be installed into the access fittings. With the Double Acting Hydraulic Retriever, equipment can be
installed into or retrieved from access fittings while the pipe system is in normal operation, i.e. under full
operational pressure.
The Double Acting Hydraulic Retriever works as a hydraulic cylinder with a piston rod moving in and
out.
The Double Acting Hydraulic Retriever is operated by either a manual (hand operated) hydraulic pump,
or an air-driven hydraulic pump.
