Уплотнительное кольцо гидронасоса Caterpillar 7R3447

The Hydraulic Pump O Ring Seal manages fluid containment within a hydraulic pump by sealing the interface positioned between the housing and the servo sleeve. When installed in its groove, the O Ring compresses against both mating surfaces to block unintended fluid movement as pressure rises, reduces, and shifts direction during pump control activity. This sealing action maintains separation between internal pressure zones so servo movement and pump response remain controlled by intended flow paths. Attributes:• Maintains sealing behavior during repeated cycles.• Supports stable pressure separation inside the pump assembly.• Aligns accurately with standard pump groove dimensions.Applications: The Hydraulic Pump O Ring Seal is used between housing and servo sleeve interfaces to control fluid containment and maintain pressure separation during hydraulic operation and service activities.
