Structure of hydraulic unit for Packer
Power pack(electrical motors) inside of
hydraulic unit. there are volt meter, pressure
gage, pressure switch, safety switch,
electrical jack, high pressure valve in front
part.
If switch is on, the oil is injected into packer
cylinder and packer rubber is expanded and
the counter part being off of switch - oil is
injected into oil tank, so the packer rubber is
in states of shrinkage.

It does not the air not to be, to use hydraulic
oil into cylinder of hydraulic packer, packer
rubber compressor it expands.
There is a single and a double and from the
lowest 32￠until the highest 500￠
