The frequency of seal and valve replacement can vary depending on several factors, including the age of the waterjet cutting system, the amount of use it receives, and the operating conditions. However, as a general guideline, it is recommended to replace the seals and valves in the intensifier pump at least once per year or after every 2,000 to 3,000 hours of operation, whichever comes first.

Seals and valves are critical components of the intensifier pump and are responsible for ensuring that the system maintains the required pressure and performance. Over time, seals and valves can become worn or damaged, which can result in leaks, reduced pressure, and other issues with the system.

Regular replacement of seals and valves can help prevent issues with the intensifier pump and ensure that the system is operating at peak performance. In addition to regular replacement, it is important to perform regular maintenance on the waterjet cutting system, including changing filters, inspecting hoses and fittings, and performing other routine maintenance tasks as recommended by the manufacturer.

If you notice any signs of problems with the seals or valves, such as leaks or reduced pressure, it is important to have the system inspected and repaired as soon as possible to prevent further damage and ensure proper cutting performance. Working with an experienced and knowledgeable technician can help ensure that the waterjet cutting system is properly maintained and any issues are addressed promptly and effectively.
