Уплотнение вала гидравлического поршневого насоса Caterpillar 4689815

The Hydraulic Piston Pump Shaft Seal forms a tight closure around the rotating shaft of the pump to stop hydraulic fluid from leaking out. This sealing action enables maintaining the required pressure inside the pump for proper fluid circulation. By reducing leakage, the seal supports pump efficiency and consistent hydraulic performance. It also protects nearby parts from fluid exposure, lowering the risk of contamination.Attributes:• Provides tight sealing around the pump shaft to prevent fluid leakage.• Maintains hydraulic pressure within the piston pump chamber.• Blocks dust, dirt, and moisture from entering the pump housing.Applications: The Piston Pump Shaft Seal is positioned within the piston pump body, around the shaft where it enters the pump housing to prevent hydraulic fluid from escaping along the shaft, ensuring that the pump operates efficiently and maintains optimal fluid pressure.
