Product Name: End Bell Spacer / Hydraulic Seal Spacer (40K) – Part No. 20458170

Description:
The End Bell Spacer 20458170 is a precision-machined, semi-wear component specifically designed for 40,000 PSI (approximately 2,758 bar) waterjet intensifier pumps. It is positioned inside the hydraulic End Bell assembly, adjacent to the snap ring and oil seals .

Its primary function is to maintain precise axial spacing between critical internal components, such as the oil seals, bearings, and the hydraulic cylinder . By occupying the correct space, the spacer ensures that the seal stack is properly compressed, the bearings are correctly preloaded, and the plunger is accurately aligned . This positioning is essential for preventing component misalignment, reducing hydraulic oil leakage, and ensuring smooth, efficient pump operation . Part number 20458170 is specifically configured for systems operating at 40,000 PSI.

Applications:

• Serves as a positioning and spacing component within the hydraulic End Bell of waterjet intensifier pumps .

• Ensures correct axial alignment of bearings, oil seals, and the hydraulic cylinder.

• Used during scheduled pump maintenance or when replacing End Bell oil seals and snap rings .

• Suitable for 40K waterjet intensifier systems.

Features:

• Positioning & Spacing: Provides accurate axial location for internal components to ensure proper compression and alignment .

• Semi-Wear Part: Does not directly contact high-pressure water but is subject to mechanical stress and vibration over time .

• Dimensional Stability: Manufactured to exact tolerances to maintain the structural integrity of the seal stack and bearing assembly .

• Corrosion Resistant: Made from materials suitable for the harsh, high-moisture environment of the hydraulic system .

Maintenance:

• Inspection Schedule: It is important to inspect the spacer for signs of wear, deformation, or corrosion during regular pump maintenance .

• Preventive Replacement: It should be replaced if the End Bell is disassembled (for seal replacement) or if it shows any visible damage, as a worn spacer will cause misalignment and accelerate seal wear .

• Installation: The spacer is typically accessible after removing the End Bell and the snap ring. It can be loosened by blowing air into one of the openings in the retainer .

• Alignment Check: Always ensure the End Bells are squared with each other using the proper assembly fixture before tightening components to prevent manifold leakage or breakage .
