94k-Integral-Diamond-Eductor-IDE-391130-1-xx.2182.3-1
Product Name: 94k Integral Diamond Eductor (IDE) Assembly (Part No. 391130-1-xx)
Description:
This component is a high-performance Integrated Diamond Eductor (IDE) cutting head assembly engineered for waterjet systems operating at 60,000–94,000 PSI (approximately 4,137–6,480 bar) . The "Integral Diamond Eductor" (IDE) design combines the diamond orifice, mixing chamber, and body into a single, precision-aligned unit .
Unlike traditional cutting heads with separate orifice and mixing chamber components, this IDE assembly offers perfect coaxial alignment from the water orifice through to the mixing tube outlet . The single-unit construction eliminates alignment errors common in multi-component designs, resulting in superior cutting accuracy, efficient water-garnet mixing, and extended component life .
This assembly is specifically designed for Extreme Pressure (EP) applications and can be mounted on dynamic or tilting head systems . Available in various orifice diameters (denoted by "-xx" suffix options such as -12 for .012 inch or -13 for .013 inch) and dual-port configurations (.281 ID), it represents an upgrade from traditional cutting head designs .
Applications:
Primary cutting head assembly for abrasive waterjet systems operating at 60,000–94,000 PSI
Mounting on dynamic or tilting head systems for bevel and 3D cutting applications
Precision cutting of metals, stone, glass, ceramics, composites, and armor plate
Features:
Integrated Diamond Eductor (IDE) Design: Combines diamond orifice, mixing chamber, and body into a single unit with perfect internal alignment
94,000 PSI Pressure Rating: Engineered for continuous operation at extreme pressures (6,480 bar) while also performing exceptionally well at 60,000 PSI
Simplified Maintenance: Fewer parts than conventional designs, resulting in easier service and longer maintenance-free performance periods
Precision Cutting: Perfectly aligned orifice-to-nozzle geometry produces superior edge quality and cutting accuracy
Garnet Efficiency: Optimized mixing chamber design can reduce garnet consumption by up to 20% per inch of cut
Dual Port Configuration: Available with .281 ID dual ports for enhanced abrasive flow versatility
Maintenance:
Mandatory Protection Requirements:
Inline High-Pressure Filter (Critical): An inline high-pressure filter such as the Short Stop Filter MUST be installed upstream to protect the integrated diamond orifice from debris, foreign objects, and contamination. This is especially important after pump rebuilds. Failure to use a filter will void warranties and damage the integrated diamond .
Component Lifespan:
The IDE design provides significantly extended service life compared to traditional separate-orifice designs
Described as offering "long, maintenance-free performance" under normal operating conditions with proper water filtration
Inspection Protocol:
Monitor cut quality regularly; deterioration in edge quality or cutting speed indicates mixing tube or diamond wear
Check for external water leakage around the cutting head assembly
Inspect the mixing tube (focusing tube) for bore wear, ovality, or flaring
Replace the mixing tube when cut quality degrades or visible bore wear appears
Water Quality Requirements:
Maintain proper water filtration to protect the integrated diamond orifice
Use clean, dry garnet abrasive of appropriate mesh size
Monitor water hardness and contaminants; poor water quality accelerates wear on all cutting head components
Installation Notes:
For dynamic/tilting head mounting, the assembly maintains the same tool center point (TCP) as original heads for direct retrofit compatibility
Replacement Criteria:
Replace the complete IDE assembly when the integrated diamond orifice is worn or damaged (individual component replacement is not possible)
Replace mixing tube as a separate wear component when bore wear is detected
