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

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

The primary function of the distance bushing is to act as a spacer for the high-pressure dynamic seals within the high-pressure cylinder assembly . It is installed inside the stainless steel high-pressure cylinder, positioned between dynamic seal components to maintain proper axial spacing and alignment within the seal stack . This component ensures that the high-pressure seals remain correctly positioned, preventing seal movement or extrusion under extreme pressure cycling.

The bushing is also described 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 life of the cylinder itself . It is rated for continuous operation at 4,137 bar (approximately 60,000 PSI) .

This component is a standard part in BFT intensifier assemblies, including CP022001/2 and HT022012/172 . It is fully compatible with other major waterjet intensifier systems including WJS, Maximator Jet, STM, and Intermac Primus . Cross-reference part numbers include 1-16392, 5300006, 106566, 10044, and HD400075 .

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 PSI (4,137 bar) and above
Compatible with BFT, WJS, Maximator Jet, STM, and Intermac Primus waterjet intensifier systems

Features:

High-Strength Steel or Brass Construction: 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, protecting the expensive cylinder from wear
High-Pressure Rating: Engineered for continuous operation at 4,137 bar (60,000+ PSI)
Lightweight: Approximately 0.1 kg for easy handling during maintenance
OEM Compatibility: Direct replacement for BFT part number CP022013/014; cross-referenced with 1-16392, 5300006, 106566, 10044, and HD400075

Maintenance:

Failure Diagnosis (When to Inspect/Replace):

Seal Stack Issues: If the 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
