Product Name: Distance Bushing / Spacer Bushing (Part No. CP022013/014)

Description:
This component is a precision-machined distance bushing (also referred to as a spacer bushing or compensating sleeve) specifically designed for BFT waterjet intensifier pumps. It is a cylindrical component typically manufactured from high-strength, wear-resistant material such as steel or brass.

Within the BFT intensifier assembly (models CP022001/2 and HT022012/172), the distance bushing serves as a critical spacing and alignment component within the high-pressure cylinder assembly. Its primary function is to maintain precise axial spacing between dynamic seal components within the high-pressure seal stack. By ensuring correct positioning of seals and related components, it prevents seal movement or extrusion under extreme pressure cycling up to 60,000-94,000 PSI (approximately 4,137-6,480 bar).

This bushing also acts as a cylinder insert that protects the high-pressure cylinder bore by serving as a sacrificial wear surface. It prevents direct contact between the dynamic seal stack and the inner wall of the expensive high-pressure cylinder, thereby extending the service life of the cylinder itself.

Applications:

• Provides proper spacing and positioning for high-pressure dynamic seals within the high-pressure cylinder assembly

• Protects the high-pressure cylinder bore from wear by acting as a sacrificial surface

• Maintains correct alignment of the seal stack under ultra-high pressure operation

• Used during scheduled preventive maintenance, major pump overhauls, or when seal stack integrity is compromised

• Suitable for ultra-high pressure waterjet systems operating at 60,000-94,000 PSI (4,137-6,480 bar)

• Compatible with BFT intensifier assemblies CP022001/2 and HT022012/172

Features:

• High-Strength Material: Precision-machined from durable, corrosion-resistant material to withstand extreme pressure cycling

• Critical Spacing Function: Maintains precise axial spacing between dynamic seal components in the high-pressure seal stack

• Cylinder Protection: Serves as an insert that prevents direct friction between seal components and the high-pressure cylinder bore

• High-Pressure Rating: Engineered for continuous operation at 4,137 bar (60,000+ PSI)

• Lightweight: Approximately 0.1 kg for easy handling during maintenance

• Direct OEM Replacement: Interchangeable with BFT part number CP022013/014

Maintenance:

Failure Diagnosis (When to Inspect/Replace):

• Seal Stack Issues: If high-pressure seals fail prematurely or external water leakage occurs, the distance bushing may be worn or damaged

• Cylinder Bore Damage: Scoring or wear on the high-pressure cylinder bore may indicate the bushing has failed to protect the cylinder surface

• Visible Wear During Overhaul: During pump disassembly, inspect the bushing for signs of scoring, galling, deformation, or wear

• Dimensional Integrity: Measure the bushing length and diameter to detect any dimensional change that could affect seal stack spacing

• Scheduled Preventive Maintenance: It is standard practice to inspect the distance bushing during major pump overhauls and replace it if any wear or damage is detected

Inspection and Replacement Guidelines:

• Full Depressurization (Critical): Before any maintenance, fully depressurize the waterjet system (high-pressure water, hydraulic system, and air supply) and follow lockout/tagout procedures

• Clean Area Maintenance: Perform the rebuild in a designated clean area to prevent contamination of components with abrasive particles

• Disassembly: Remove the high-pressure cylinder end cap and extract the seal stack to access the distance bushing

• Thorough Cleaning: Clean the bushing and its mounting cavity with a soft cloth and low-pressure water. Remove all debris, old seal residue, and mineral deposits. Do not use abrasive tools

• Surface Inspection: Inspect the bushing outer and inner surfaces for scoring, pitting, galling, or uneven wear patterns

• Dimensional Measurement: Measure the bushing length and diameter at multiple points using precision measuring tools to detect out-of-tolerance conditions

• Replace as a Set: When servicing the high-pressure seal stack, it is recommended to replace the distance bushing simultaneously with the dynamic seals, O-rings, and backup rings to ensure optimal seal stack performance

• Cylinder Bore Inspection: When replacing the distance bushing, inspect the high-pressure cylinder bore for scoring, pitting, or wear. Replace the cylinder if damage is found, as a damaged cylinder will compromise seal performance

• Lubrication: Apply a thin, uniform layer of manufacturer-recommended high-pressure grease to the bushing during installation

• Torque Compliance: When reassembling the cylinder end cap, tighten all retaining hardware to the specific torque values listed in the equipment service manual

• Recommended Purchase: To ensure proper fit and reduce machine downtime, it is advisable to purchase the high-pressure cylinder and distance bushing together as a matched set

• Storage: Store spare bushings in a clean, dry environment to prevent surface damage before use
