Product Name: Sealing Ring / Back-up Ring (Part No. IP016040/150)

Description:
This component is a sealing ring, specifically a back-up ring or support ring, designed for the high-pressure intensifier pump in waterjet cutting systems . It is a precision rigid ring manufactured from high-strength, wear-resistant material such as PTFE, PEEK, or engineered polymer.

Installed adjacent to a dynamic seal such as a Quad-Ring or U-cup within the high-pressure cylinder assembly, its primary function is to provide anti‑extrusion support . By filling the clearance gap between the primary seal and the metal gland wall under ultra‑high pressure (60,000–94,000 PSI / approx. 4,137–6,480 bar), it prevents the softer elastomeric seal from being forced into the gap, which would otherwise cause rapid seal failure, pressure drop, and external water leakage .

The sealing ring is specifically engineered for static or dynamic sealing applications where the seal stack is subject to extreme pressure cycling. As a critical consumable component, it must be replaced periodically as part of regular pump maintenance.

Applications:

Provides anti‑extrusion support for dynamic seals (Quad-Rings, U-cups) in the high‑pressure cylinder of waterjet intensifier pumps .
Used in static sealing applications where extreme pressure reliability is required.
Suitable for ultra‑high pressure waterjet systems operating at 60,000–94,000 PSI.
Compatible with BHDT, BFT, and other standard waterjet intensifier systems.

Features:

Rigid anti‑extrusion design: The non‑deformable construction prevents primary seal extrusion under extreme pressure .
Precision dimensions: Manufactured to exact tolerances for a perfect fit within the designated seal groove.
Critical consumable component: A worn or missing sealing ring will lead to immediate seal failure and high‑pressure water leakage .
OEM compatibility: Direct replacement for BHDT part number IP016040/150.

Maintenance:

Failure Diagnosis (When to Replace):

External water leakage: Visible water weeping from the cylinder end cover or weep hole is the primary indicator of seal stack failure, requiring replacement of the sealing ring together with the primary seal .
Pressure drop: Inability to maintain rated cutting pressure suggests internal seal extrusion caused by an unsupported gap.
Visible damage during disassembly: Inspect the sealing ring for deformation, cracking, splitting, flattening, or wear; any visible damage warrants immediate replacement .
Scheduled preventive maintenance: Standard practice to replace the sealing ring together with the dynamic seal during major pump overhauls (typically every 1,000–2,000 operating hours or when seal wear is detected) .

Inspection & Replacement Guidelines:

Always replace with primary seals: The sealing ring is a single‑use consumable. Always replace it with a new one whenever the adjacent dynamic seal (e.g., Quad-Ring or U-cup) is replaced .
Full depressurisation (critical): Before any maintenance, fully depressurise the waterjet system and follow lockout/tagout procedures.
Clean installation: Perform the rebuild in a designated clean area. Thoroughly clean the seal groove and all mating surfaces with a soft, lint‑free cloth, removing all debris, old seal residue, and mineral deposits.
Lubrication: Apply a thin, uniform layer of manufacturer‑recommended high‑pressure grease during installation to prevent pinching, rolling, or tearing .
Groove inspection: Inspect the seal groove for nicks, burrs, sharp edges, or damage that could compromise the seal stack.
Replace as a set: When servicing the high‑pressure sealing stack, replace all components (dynamic seal, back‑up ring, support rings) simultaneously using a complete repair kit .
