  • Leakage or seal failure at the affected assembly
  • Replacement required during scheduled pump rebuild
  • Maintaining OEM-equivalent performance and sealing

This kit is used by service technicians to restore pump performance on HERO industrial and plural-component equipment. All components are manufactured to OEM-equivalent dimensions for proper sealing and reliable field operation.
