SUB-SEA USAGE
The Equalizer range of HP hydraulic hand pumps are fitted
with a sealed-bladder type reservoir system that allows
for sub-sea operation.
The SWi5TE 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 HP350S/D hydraulic 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 HP350S/D
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 SWi5TE 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.

MAINTENANCE PLAN
1.
Rub components down with a dry cloth to remove
moiusture.
2.
Coat EVERY surface and contact point with a
corrosion inhibitor. Where nexessary, coat inside
and outside of component e.g. VC10
3.
Nuts and threads must also be coated with a
corrosion inhibitor.
4.
Once surfaces have been coated, seal individual
components in clear plastic bags or clear vaceem
bags or clear shrink wrap.
NOTE: bags/shrink wrap must be clear for visibility.
Take care when using shink wrap that the tool is /
components are still easy to see.
5.
Remove all or, where not vacuum sealed, as much
air from bags as possible.
6.
Once bags have been closed and sealed DO NOT
re-open. Any visual inspections must be done with
closed and sealed bags. If bags are opened the
components will have to be dried, re-coated and re-
sealed in bags/shrink wrap.
7.
Replace silica gel (100g) EVERY TIME the case is
opened.
NOTE: depending on moisture content of air, silica
gel should be changed weekly.
8.
Visually inspect kits after 30-days and every 30-days
thereafter. Remember to replace silica gel before
closing case.
