STORAGE & TRANSPORTATION

Equalizer tools should be stored in a cool dry place. Tools 
should always be cleaned, serviced and lubricated prior to 
storage. Ensure that tools are stored in their designated 
packing cases.

SUB-SEA USAGE

Using TFA12TE Sub-Sea

The TFA12TE is actuated by means of single-acting 
spring-return hydraulic cylinder and can be used sub-sea 
providing the following actions are taken: 
•  The gauge and manifold are removed from the 

Equalizer  HP  hand-pump  and  the  coupler  is  fitted 
directly to the pump outlet (tools in this configuration 
can be requested from Equalizer).

•  The tool is connected to the Equalizer HP hand-pump 

whilst still top-side.

•  The pump release valve is fully opened and remains 

open until the tool has descended to the working 
depth. This will allow the pressure to equalise.

•  The tool is actuated via the hand-pump by a diver.
•  Upon completion of works the release valve is left in 

the fully-open position until the tool has ascended to 
the surface.

•  The tool and pump are stripped-down, cleaned and 

lubricated immediately to minimise corrosion. 

Please note that a sub-sea TFA12TE tool cannot be 
operated from top-side by use of a down-line. The return 
springs  in  the  hydraulic  cylinders  do  not  have  sufficient 
force to close the tool if used with a down-line from a 
top-side pump, therefore the standard hydraulic tools will 
not function correctly and may jam in place if used in this 
configuration.
