Product ID: 05144688 – Sealing Head Assembly (Intensifier Pump Check Valve Assembly)

Description:
This component is a sealing head assembly, also known as a high-pressure check valve assembly or sealing head cartridge, designed for waterjet intensifier pumps . It is a complete, pre-assembled unit that integrates the inlet and outlet check valves, high-pressure seals, poppets, seats, springs, and retaining components within a single housing . This assembly mounts at the high-pressure end of the intensifier pump between the high-pressure cylinder and the outlet plumbing . The sealing head assembly is a critical component that controls the one-way flow of water into and out of the high-pressure cylinder during the intake and compression strokes . This assembly is rated for ultra-high pressure operation .

Applications:

• Used as the complete check valve assembly at the high-pressure end of a waterjet intensifier pump .

• Installed between the high-pressure cylinder and the high-pressure outlet line to direct pressurized water toward the cutting head .

• Houses both the inlet (intake) and outlet (discharge) poppet valves, seats, springs, and high-pressure seals in a single integrated housing .

• Suitable for ultra-high pressure waterjet systems, typically operating at 60,000 PSI (approximately 4,137 bar) .

Features:

• Complete pre-assembled unit includes the sealing head body, inlet poppet, inlet seat, outlet poppet, outlet seat, poppet springs, poppet retainers, and all associated high-pressure seals and O-rings .

• Precision-machined housing (sealing head body) with integrated inlet and outlet ports and internal valve cavities .

• Constructed from high-strength, corrosion-resistant stainless steel to withstand extreme pressure cycling and abrasive environments .

• Engineered for drop-in replacement, simplifying maintenance and reducing pump downtime compared to rebuilding individual components .

• Includes precision cone sealing surfaces and poppet seats for leak-tight metal-to-metal sealing .

• Rated for 60,000 PSI continuous operation with PRO versions available for 90,000 PSI systems .

Maintenance:

• Complete Assembly Replacement: This component is designed as a complete, pre-assembled unit. When internal seals, seats, or poppets wear, replace the entire sealing head assembly to ensure optimal performance and reliability .

• Inspection: During pump overhaul, inspect the sealing head assembly for signs of external leakage, pressure drop, or performance degradation. If any issues are detected, replace the complete assembly .

• Sealing Surface Check: The internal cone sealing surfaces and poppet seats are critical for leak-free operation. Wear or damage to these surfaces cannot be reliably repaired in the field; assembly replacement is recommended .

• Torque Specification: When reinstalling, tighten the sealing head assembly to the torque values specified in the equipment service manual .

• Lubrication: Apply manufacturer-recommended anti-seize compound or thread lubricant to threads during reassembly to prevent galling and ensure accurate torque application .

• Compatibility Verification: Before installation, verify that the sealing head assembly matches the specific intensifier model (e.g., SL-IV, SL-V, Classic, OEM), pressure rating (60,000 PSI or 90,000 PSI), and high-pressure cylinder configuration .

• Full Depressurization: Always fully depressurize the waterjet system and follow lockout/tagout procedures before removing or servicing the sealing head assembly .

• Seal Replacement: When reinstalling, always replace all O-rings and sealing elements associated with the sealing head assembly-to-cylinder interface .

• Storage: Store spare sealing head assemblies in a clean, dry environment, in protective packaging to prevent contamination or damage to precision sealing surfaces before use .
