Product Name: Waterjet Seal Assembly

Description:
This component is a collective term for various sealing elements used in high-pressure waterjet cutting systems. These seals prevent leaks of ultra-high-pressure water up to 60,000-90,000 psi. They include O-rings, backup rings, dynamic seals, and cartridge assemblies, typically made from materials like PTFE, Polyurethane, NBR, EPDM, or FKM (Viton).

Applications:

• Used in sealing head assemblies to maintain a watertight seal between the high-pressure cylinder and the plunger.

• Installed in dynamic applications such as the high-pressure piston or swivel joints to prevent fluid bypass.

• Employed in static sealing applications for fittings, connections, and cutting head components.

• Suitable for both pure water and abrasive waterjet cutting systems.

Features:

• High-Pressure Resistance: Engineered to withstand extreme pressure surges and prevent extrusion.

• Wear Resistance: Constructed from durable polymers and elastomers to resist abrasion from high-velocity water and garnet.

• Material Variety: Available in PTFE (low friction), Polyurethane (high wear resistance), and FKM/EPDM (chemical compatibility).

• Low Friction: Spring-energized PTFE seals minimize friction during high-speed reciprocating motion.

• Modular Design: Cartridge-style "drop-in" seal assemblies simplify maintenance and ensure correct orientation.

Maintenance:

• Inspect Sealing Surfaces: Check the inside diameter of the high-pressure cylinder for scratches, pits, or debris buildup each time seals are replaced.

• Clean and Polish: Use 600-grit sandpaper with a circumferential wiping motion to polish the cylinder bore; do not drag along the length.

• Prevent Contamination: Perform seal replacements in a designated clean area. Wear disposable gloves to keep natural oils and abrasive particles off new seals.

• Lubrication: Lightly coat seal components with high-pressure grease (e.g., FML-2) during installation to prevent dry start-up and ensure proper seating.

• Monitor Water Quality: High-quality, filtered water is critical for maximizing the life of high-pressure seals.

• Replace on Schedule: Replace seal assemblies whenever the sealing head is removed, or when signs of leakage (warm cylinders or weep holes) are detected.
