Product ID: 05049812 – Mounting Stem (Intensifier Tie Rod / Mounting Rod)

Description:
This component is a mounting stem, also known as a mounting rod, intensifier tie rod, or topworks stem, designed for high-pressure waterjet intensifier pumps . It is a precision-engineered, elongated cylindrical rod manufactured from high-grade stainless steel, serving as a critical structural fastener within the intensifier assembly. The mounting stem is designed to secure and align the internal components of the waterjet intensifier pump, including the high-pressure cylinder, seal assemblies, and end caps, ensuring consistent pressure distribution and structural integrity during high-pressure cutting operations .

The component has an approximate weight of 2.44 kg and is typically used in pairs within the intensifier assembly . Alternative cross-reference part numbers include SL05049812 and 103427 .

Applications:

• Used in waterjet cutting intensifier pumps as a tie rod or mounting stem that secures the high-pressure cylinder, hydraulic cylinder, and end caps into a single rigid assembly .

• Installed longitudinally through the intensifier assembly, providing clamping force to hold the cylinder stack together against ultra-high pressure forces.

• Suitable for ultra-high pressure waterjet systems operating at 55,000–60,000 PSI (approximately 3,800–4,137 bar) and compatible with KMT-style intensifier cylinders and SL-V, SL-IV, and Classic series intensifier assemblies .

Features:

• Constructed from high-grade stainless steel, offering excellent corrosion resistance and fatigue strength even under continuous exposure to high-pressure water and harsh operating environments .

• Precision CNC-machined to exact specifications, ensuring a perfect fit within the intensifier cylinder assembly and guaranteeing smooth assembly and reliable sealing .

• Provides stable alignment between the high-pressure cylinder, plungers, and seals, helping to prevent vibration, water leakage, and premature wear of internal components .

• Engineered to withstand extreme pressure cycling without deformation or fatigue failure.

• Designed for both OEM replacement and aftermarket servicing of waterjet pumps used in industrial applications .

Maintenance:

• Critical Alignment Component: The mounting stem plays a vital role in securing and supporting the internal structure of the waterjet intensifier pump. Proper torque and alignment are essential for consistent pressure distribution .

• Visual Inspection: During pump overhaul, inspect each mounting stem for signs of thread damage, corrosion, galling, bending, or stress cracking. Replace any stem showing visible wear or damage.

• Torque Specifications: When reinstalling, tighten mounting stem nuts to the specific torque value listed in the equipment service manual. Uneven or incorrect torque can cause misalignment, seal failure, and premature component wear.

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

• Replacement Schedule: Even if no visible damage is present, periodic replacement of mounting stems as part of scheduled preventive maintenance is recommended to ensure continued structural integrity and alignment precision .

• Pair Replacement: When replacing mounting stems, replace them as a complete set (typically in pairs) to ensure even clamping force and balanced alignment.

• Full Depressurization: Always fully depressurize both the hydraulic system and the high-pressure water system before removing or servicing the mounting stems.

• Compatibility Check: Ensure the replacement mounting stem matches the specific intensifier model (SL-IV, SL-V, Classic series) and pressure rating (55,000–60,000 PSI) to guarantee proper fit and function .
