A
PistoLite
accumulator has a light weight piston where the dynamic seals are
aligned with the solid piston center, and where the both gas and liquid
skirt ends have graphite filled Teflon guide rings.
HydroTrole piston accumulators have a sealing geometry
that ensures pre-charge gas retention with immeasurable loss over an
MTBF (meantime between failure) design criteria of 32 million cycles,
with minimum hysteresis break out stiction achieved by placing the
dynamic seals so closely adjacent each other that seal deflection
ensures that the lubricant held between the seals instantly reaches the
same pressure as the oil and the pre-charge gas. All pistons with so
lightly loaded dynamic seals are prevented from experiencing a
differential pressure at gas end and at liquid end of stroke by a static
encapsulated shut-down seal than face seals against the end of the
piston skirt on each side. Piston accumulators are recommended because
when they do begin to go down it is gradual progressive, and
determinate. They are recommended for emergency standby power.
Main Features: Solid Light-Weight Piston,
Close-Coupled Seals, Dual Graphite-Filled Bearing Strips for Low
Stiction, Various Seal Elastomers, Zero Leakage When Shut Down, Super
Fast R Locking, Flow-Thru Port Facility.
