The operation of a hydraulic ram pump is based on the principles of momentum and inertia. Water flows through the drive pipe and enters the ram body. As the flow speed increases, the momentum of the water causes the waste valve to initially open. When the waste valve closes suddenly, the water's momentum generates a pressure spike in the system.

3. Pressure Maintenance Hydraulic systems rely on maintaining a specific pressure to function effectively. Oil seals help retain this pressure by providing a secure barrier that prevents fluid escape, which is crucial for optimal motor performance.

3. Application Type The nature of the application—whether dynamic, static, or mixed—will influence the choice of seal type, as each type offers different benefits.
