 SENTRY
Suction Stabilizers
Without a sufficient supply of fluid a pump will
not perform efficiently. Fluid "starvation" is caused
by unbalanced hydraulics from friction, acceleration,
and head. A reciprocating pump further complicates
the issue by emitting high-frequency pressure waves
created by the inlet valves opening and closing.
For example, in high inlet pressure situations,
a pump's inlet valves create "water hammer" by their
opening and closing action; increasing pipe and
pump damage, and draining system efficiency.
In suction lift and horizontal suction applications,
the inlet valve action actually decreases inlet
fluid pressure. A "starved" or cavitating pump will
be unable to produce specified flow rates due to
the incomplete filling of cylinders and liquid chambers;
in addition, cavitation will result in premature
failure of pump parts.
SENTRY Suction Stabilizers at the pump's inlet will
act as an accumulator, reducing pressure fluctuations
and aid in filling the pump head with fluid during
each inlet stroke. In high suction lift applications
it is also important not to lose the acceleration
of the fluid created with each suction stroke of
the pump.
SENTRY Suction Stabilizers will momentarily maintain
the flow of the accelerated fluid. The fluid flows
into the stabilizer as the pump shifts, then out
as the inlet valve re-opens--maintaining even pressure
and steady flow--eliminating cavitation.
