An aluminum thrust plate in a Parker gear pump is a critical wear component, In a gear pump, the wear plate is the stationary component against which the rotating gears (the gear faces) slide.
parker thrust plates (PLACA DE ENCOSTO)seal the gear section at the sides of the gears. Wear here will allow internal slippage, meaning the oil will bypass within the pump. The maximum wear allowable is .002″. Replace the thrust plates if they are scored, eroded or pitted. Check the center of the thrust plates where the gears mesh. Erosion here indicates oil contamination. Pitted thrust plates indicate cavitation or oil aeration. Discolored thrust
plates indicate overheating, probably insufficient oil.
Characteristic The thrust plates are designed with special aluminum materials,and own good antifriction,wear resistance and yield strength. Improved mechanical & volumetric efficiency. Good antifriction and wear resistance Light and space saving designs Extended service life. Reduce noise and shock
Application Specialize in hydraulic external gear pumps and motors.
