hydraulic pump’s inlet line (suction line
out
from
the reservoir
to
the pump)
should be located near the bottom of the
tank, well below the oil level. The suction
line should protrude a minimum of two
(2”) inches into the reservoir to keep it
away from potential contaminant surface
buildup.
• A baffle or baffles should be included to
prevent sloshing, or centrifugal motion of
the oil; the goal is to break up direct flow
of the oil from the return point to the
suction point. This allows for the cooling
action contact with the tanks’ inner
surfaces, and promote separation of any
air or contaminants that interact with the
flowing oil.
An ideal baffle design would position
several (but not too many) baffles to
promote an ‘S’ shape flow within the
reservoir, as viewed from above. The
area of the end gaps should be at least
twice the area of the suction line
diameter.
• A drain port with plug, situated at the
lowest point of the reservoir, is needed to
assure complete draining. It should be
installed using an adaptor or housing
which does not protrude above the inner
surface of the floor of the tank. It should
be visible and accessible for removal,
with sufficient space available for
catching the waste oil.
• If the return line entrance to the tank is
located near the top, it should be
extended downward within the tank to
minimize foaming and aeration of the
circulating oil. This extends oil integrity,
which in turn helps to maintain system
performance and reliability.
• An inline filter on the return line is
needed to protect the system against
contaminants being introduced into the
oil. The filter should be mounted
externally from the reservoir in a location
that allows for easy of service access.
• A breather and fill cap is needed at the
oil fill port, which needs to be located
above the system oil level. The breather
cap acts to both filter air that is drawn
into the reservoir as the oil level
diminishes, and bleeds air out as the
