Уплотнительное кольцо гидронасоса Caterpillar 7R3446

The Hydraulic Pump O Ring Seal manages fluid containment within a hydraulic pump by sealing clearance paths between mating interfaces where fluid transfer is not intended. When installed, the seal compresses within its groove and maintains surface contact to block fluid passage as pressure rises, reduces, and shifts direction during pump operation. This sealing behavior maintains separation between pressure zones so hydraulic flow follows the intended control and actuation paths.Attributes:• Controls fluid sealing within hydraulic pump interfaces.• Maintains separation between pressure zones.• Accommodates pressure increase and pressure reduction cycles.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.
