Product Name: Plunger Housing Water Fitting, Top (Part No. 201215)

Description:
This component is a precision-engineered high-pressure connector specifically designed for the top section of the plunger housing in waterjet intensifier pumps . Its primary function is to provide a secure, leak-free connection between the high-pressure water line and the plunger assembly, ensuring consistent water delivery to the intensifier for smooth and efficient cutting operations .

Manufactured from premium-grade stainless steel or nickel-chrome alloy, this fitting offers exceptional corrosion resistance, pressure durability, and dimensional accuracy . Each fitting is CNC-machined and internally polished to maintain smooth water flow and minimize turbulence, ensuring consistent pressure stability even under continuous operation up to 60,000 psi (approximately 4,100 bar) . The precision threads and sealing surfaces guarantee a perfect fit, reducing the risk of leaks, vibration, and wear during extended use . This component is fully compatible with KUNDA, KMT, FLOW, OMAX, and AccuStream waterjet systems .

Applications:

• Connects high-pressure water line to the top section of the plunger housing in waterjet intensifier pumps

• Directs high-pressure water flow into the plunger chamber for consistent pressure delivery

• Integrates with plunger housing, check valve assemblies, and high-pressure manifolds

• Suitable for ultra-high pressure waterjet systems operating at 60,000 PSI and above

• Used in metal cutting, stone fabrication, ceramic machining, and composite material processing 

Features:

• High-Strength Material: Manufactured from premium-grade stainless steel or nickel-chrome alloy for exceptional corrosion resistance and durability 

• Precision-Machined: CNC-machined to exact tolerances with polished internal passages for turbulence-free water flow 

• High-Pressure Rating: Engineered for continuous operation at 60,000 PSI (4,100 bar) and above 

• Leak-Free Connection: Precision threads and sealing surfaces ensure tight, vibration-resistant connection 

• Cross-Brand Compatibility: Fully compatible with KUNDA, KMT, FLOW, OMAX, and AccuStream waterjet systems 

Maintenance:

Inspection Procedures:

• Regular Inspection: Check the fitting for signs of cracking, thread galling, or corrosion during pump rebuilds or routine maintenance

• Seal Condition: Inspect O-rings or sealing washers for wear, hardening, or damage; replace immediately if compromised

• Thread Condition: Verify threads are clean and free from damage, galling, or cross-threading

Replacement and Installation Guidelines:

• Seal Replacement: Always replace O-rings or sealing washers when reinstalling the fitting to ensure leak-proof connection

• Torque Compliance: Tighten the fitting to the specific torque value listed in the equipment service manual to avoid damaging the housing or causing leaks

• Thread Lubrication: Apply a thin layer of high-pressure thread lubricant or anti-seize compound to threads during reassembly to prevent galling

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

• Replacement Criteria: Replace the fitting immediately if cracks, thread damage, or severe corrosion is detected

• Use Proper Tools: Use correctly sized wrenches to avoid damaging the fitting surfaces
