The “Without Backpressure Ring” High-Pressure Seal Repair Kit, model 1-11467, is a critical maintenance component specifically designed for high-pressure water jet Booster Pump systems. Its primary purpose is to replace high-pressure seal elements, thereby restoring the system’s sealing performance and ensuring stable and reliable operation at ultra-high pressures.
This repair kit includes various high-pressure seals and O-rings required for routine maintenance, but does not include a backpressure ring or auxiliary sealing elements. Therefore, it is ideal for maintenance scenarios where only the primary seals need to be replaced, while the auxiliary sealing elements remain in good working condition.
Timely replacement of seals helps effectively prevent leaks, pressure loss, seal failure, and unexpected downtime caused by equipment malfunctions.

Is the “Without Back-Pressure Ring” High-Pressure Seal Repair Kit (Part No. 1-11467) considered a wear-and-tear item?

Yes—the “Without Back-Pressure Ring” High-Pressure Seal Repair Kit (Part No. 1-11467) is a typical wear-and-tear kit.
The seals in this kit must operate continuously under extremely high pressure, intense friction, and sustained sealing contact. Over time, these seals naturally experience aging phenomena such as wear, hardening, cracking, or loss of elasticity, which directly affect the overall performance of the pump and the stability of cutting operations.
We strongly recommend that users strictly adhere to established maintenance schedules for regular replacement to avoid costly repairs and prevent production process interruptions.
