Product ID: 05144357 – Sealing Head Body (Intensifier Pump Component)

Description:
This component is a sealing head body for high-pressure waterjet intensifier pumps. It is a precision-machined, high-strength stainless steel housing that serves as the structural foundation of the sealing head assembly, which mounts at the high-pressure end of the intensifier pump . The body contains internal cavities and precision sealing surfaces that house the inlet check valve, outlet check valve, high-pressure seals, and the interface to the high-pressure cylinder . This component is rated for ultra-high pressure operation and is compatible with specific intensifier pump models .

Applications:

• Used as the primary structural housing at the high-pressure end of an intensifier pump in waterjet cutting machines .

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

• Houses the inlet and outlet poppet valves and associated sealing components that control unidirectional water flow .

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

Features:

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

• Precision-machined to tight tolerances for proper fit with mating components such as the high-pressure cylinder, cone ring, and check valve assemblies .

• Features precision cone sealing surfaces that create metal-to-metal high-pressure seals when compressed against mating components .

• Internal cavities are precisely machined to accept inlet and outlet poppets, springs, seats, and seal components .

• Designed for continuous operation under extreme pressure cycling without fatigue failure .

• Modular design allows for replacement of internal wear components (seats, poppets, seals) without discarding the body .

Maintenance:

• Inspection: During pump overhaul, inspect the sealing head body for signs of cracking, corrosion, pitting, erosion, or thread damage. Pay particular attention to the cone sealing surfaces and internal poppet valve seats .

• Cone Surface Refinishing: If minor scratches or pitting are present on the cone sealing surface, they may be refinished using 600-grit sandpaper with radial (circular) motion . Use a flat piece of thick plate glass with 400-grit wet/dry sandpaper for flat sealing surfaces, rotating the head 10-15 degrees between strokes to maintain flatness .

• Poppet Seat Inspection: Inspect the inlet and outlet poppet valve sealing surfaces for pitting, scratches, or jetting erosion . Severe damage may require replacement of the sealing head body .

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

• Compatibility Verification: Before installation, verify that the sealing head body matches the specific intensifier model and pressure rating .

• Replacement Criteria: Replace the sealing head body if cracks are detected, if cone or poppet sealing surfaces are severely damaged beyond refinishing limits, if internal erosion is excessive, or if threads are damaged .

• Seal Replacement: When reinstalling, always replace all O-rings, backup rings, and sealing elements associated with the sealing head body .

• Torque Compliance: When reinstalling, tighten all retaining components to the torque values specified in the equipment service manual using proper lubrication .
