As the power source and actuators within the system, these components contain numerous high-speed rotating precision mating surfaces.
Rotary Shaft Sealing: Prevents fluid leakage from the shaft extension. Commonly employs oil seals (such as TC skeleton oil seals) or specialised rotating Gleitring seals. Requires resistance to high speeds and wear. Distributor Plate/Valve Plate Seals: Flat static seals isolating high-pressure and low-pressure zones. Commonly employ O-rings or specialised flat gaskets. Must withstand high pressure and fatigue. Piston/Vane Seals: Dynamic seals within the pump, demanding exceptional material properties and manufacturing precision.
