Piston Seal 1-11673 for Waterjet Pump Sealing System Parts

The Piston Seal 1-11673 is a critical sealing component used in Waterjet Intensifier pump systems. Its main function is to seal the piston assembly within the hydraulic or high-pressure cylinder, preventing fluid leakage while maintaining stable pressure during reciprocating operation.
This seal operates under extreme conditions involving high pressure, continuous motion, friction, and thermal load. It ensures efficient energy transfer from the hydraulic system to the high-pressure water output system, directly affecting cutting stability and pump efficiency.
A high-quality piston seal is essential for maintaining pressure integrity, reducing leakage, and ensuring long-term reliable operation of the intensifier system.

Is Piston Seal 1-11673 a Wear Part?

Yes — the Piston Seal 1-11673 is a typical wear part.
Because it is constantly exposed to high pressure, reciprocating movement, and friction against the cylinder wall, the sealing material gradually wears, hardens, cracks, or loses elasticity over time.
If not replaced in time, it can cause hydraulic leakage, pressure loss, unstable operation, and damage to other internal components.
Regular inspection and scheduled replacement are strongly recommended.
