Product ID: 05007786 – Bushing Retainer Flange

Description:
This component is a bushing retainer flange, also known as a hydraulic cartridge flange, designed for high-pressure waterjet intensifier pumps . It is a precision-machined stainless steel ring-shaped component that serves as a retaining and alignment element for the bushing assembly, which guides the reciprocating ceramic plunger .

This part is specifically used on the 0.88 inch plunger block and is compatible with intensifier pumps operating at 55,000–60,000 PSI (approximately 3,800–4,137 bar) . Alternative part numbers include 1-12564 .

Applications:

• Used in waterjet cutting intensifier pumps to retain and align the bushing assembly that guides the reciprocating ceramic plunger.

• Installed in the high-pressure cylinder area of intensifier pumps, specifically on the 0.88 inch plunger block.

• Suitable for ultra-high pressure waterjet systems operating at 55,000–60,000 PSI.

• Compatible with SL-IV, SL-V, Classic series, and OEM intensifier assemblies ranging from 15 to 60 horsepower .

Features:

• Constructed from corrosion-resistant stainless steel for durability in waterjet operating environments .

• Precision-machined internal bore to ensure proper fit and concentricity with the ceramic plunger and bushing assembly.

• The internal bore surface is finished to a high standard of smoothness to prevent unnecessary wear on the ceramic plunger .

• Engineered to maintain proper alignment of the ceramic plunger during high-frequency reciprocating motion, preventing misalignment that could lead to plunger damage.

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

Maintenance:

• Critical Alignment Component: The concentricity of the bushing retainer flange is critically important. Poor concentricity can cause ceramic plunger damage or breakage during operation .

• Regular Inspection: It is strongly recommended to inspect the bushing retainer flange regularly for signs of internal bore wear, galling, or surface degradation .

• Bore Condition Check: Pay particular attention to the smoothness and roundness of the internal bore. If the internal bore becomes rough, scored, or out-of-round, replace the flange immediately to prevent plunger damage .

• Replacement Schedule: Even if no visible damage is present, periodic replacement of the bushing retainer flange as part of scheduled preventive maintenance is recommended to ensure continued proper plunger alignment.

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

• Compatibility Check: Ensure the replacement flange matches the specific intensifier model (0.88 inch plunger block, 55,000–60,000 PSI rating) to guarantee proper fit and function .
