Product ID: 05144209 – End Flange (Intensifier Pump Component / High-Pressure Cylinder Flange)

Description:
This component is an end flange, also known as a high-pressure cylinder end flange or intensifier end flange, designed for high-pressure waterjet intensifier pumps. It is a precision-machined, heavy-duty flange component that serves as the end closure and structural mounting interface for the high-pressure cylinder assembly within the intensifier pump. The end flange secures the high-pressure cylinder, seals, and internal components, withstanding extreme axial forces generated during water compression. The component has a weight of approximately 17.79 lbs (8.07 kg). Alternate or cross-reference part numbers include 103682 .

Applications:

• Used in waterjet intensifier pumps as the end flange that seals and secures the high-pressure cylinder assembly.

• Installed at the high-pressure end of the intensifier, providing a mounting interface between the high-pressure cylinder and the hydraulic piston or check valve assembly.

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

• Compatible with SL-IV, SL-V, Classic, and OEM intensifier assemblies.

Features:

• Constructed from high-strength, corrosion-resistant alloy steel or hardened stainless steel to withstand extreme pressure cycling and axial loads.

• Precision-machined mating surfaces and sealing grooves to accommodate high-pressure O-rings, backup rings, and sealing elements.

• Engineered to provide structural integrity and maintain proper alignment between the high-pressure cylinder and adjacent components.

• Designed to resist fatigue failure under continuous pressure cycling from zero to maximum operating pressure.

• Heavy-duty construction weighing approximately 17.79 lbs (8.07 kg) ensures stability and vibration resistance during pump operation .

• Precision-drilled bolt holes or threaded mounting features for secure attachment to the cylinder body and pump frame.

Maintenance:

• Inspection: During pump overhaul or preventive maintenance, inspect the end flange for signs of cracking, corrosion, pitting, or thread damage. Pay particular attention to sealing surfaces and mounting bolt holes.

• Sealing Surface Check: Inspect all O-ring grooves and sealing surfaces for scratches, nicks, or wear that could compromise high-pressure sealing. Replace the flange if sealing surfaces are damaged beyond repair.

• Torque Specification: When reinstalling, tighten all mounting bolts or retaining screws to the specific torque values listed in the equipment service manual using a staggered (cross) tightening pattern to ensure even clamping force distribution.

• Thread 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 end flange matches the specific intensifier model (SL-IV, SL-V, Classic, OEM), pressure rating (60,000 PSI), and high-pressure cylinder configuration.

• Full Depressurization: Always fully depressurize both the hydraulic system and the high-pressure water system before removing or servicing the end flange. Follow lockout/tagout procedures.

• Replacement Criteria: Replace the end flange if cracks, severe corrosion, thread damage, or sealing surface damage is detected. Do not attempt to repair a cracked or severely damaged flange.

• Gasket/Seal Replacement: Always replace all O-rings, backup rings, and sealing elements associated with the end flange during each service or overhaul.
