Assignee: PERFORMANCE PULSATION CONTROL, INC.
Field: Chemical engineering (Chemistry)
Classification: CPC F  B  E | IPC B  E  F

Claim 8:
9. A system, comprising:
a strainer cross coupled to a pump discharge to filter large particles;
a bladder saver device coupled to the strainer cross to be in fluid communication with a cross fluid passage of the strainer cross, the bladder saver device includes:
a housing that includes an internal passage for a pulsated fluid flow, wherein the housing is formed of an upper body ring with an internal annulus, a middle body ring, and a lower body ring,
a bleed plate mounted within the internal passage and movable, in response to increasing fluid pressure of fluid flowing through the internal passage, between a first position in which the pulsated fluid flow through a fluid outlet for the internal passage is least encumbered by the bleed plate and a second position in which the pulsated fluid flow through the fluid outlet is restricted by the bleed plate,
a central shaft coupled to the housing and extending through the internal passage, wherein the bleed plate floats around the central shaft between the first position and the second position, and
a throat plate coupled to the central shaft, wherein the throat plate is fixed within the housing in a space defined by the internal annulus and an outer surface of the middle body ring; and

a pulsation dampener coupled to the bladder saver device to be in fluid communication with the internal passage,
wherein the bleed plate includes a plurality of holes to allow equalization of pressure through the internal passage when a fluid pressure of the pulsated fluid flow causes the bleed plate to move into the second position.
