29mm Inner Diameter Piston Pump Cover Ring Caterpillar 6151771

The Piston Pump Cover Ring is used to maintain pressure integrity within hydraulic piston pumps used in equipment. It fits securely into the designated groove on the pump cover or housing, preventing hydraulic fluid from leaking during pump operation. It supports proper alignment and sealing of internal pump parts, which is necessary for sustaining consistent pressure and flow rates. The ring ensures that the piston pump operates efficiently under varying load conditions by preserving the internal hydraulic pressure required for the actuation and movement of components. Attributes:• Reduces the risk of internal fluid leakage.• Minimizes wear caused by misalignment and pressure shifts.• Helps maintain stable internal hydraulic pressure.Applications: The Piston Pump Cover Ring is positioned in the piston pump cover. It secures the cover in place and helps maintain the alignment and containment needed for stable pump operation.
