Product Name: Plunger Housing Water Fitting, Bottom (Part No. 201217)

Description:
This component is a precision-engineered high-pressure inlet connector specifically designed for the bottom section of the plunger housing in waterjet intensifier pumps . Its primary function is to direct high-pressure water flow into the plunger chamber, ensuring smooth hydraulic performance and consistent pressure delivery to the cutting head . Manufactured from hardened stainless steel or corrosion-resistant alloy, this fitting provides outstanding strength, corrosion resistance, and long-term pressure endurance at up to 60,000 PSI (approximately 4,100 bar) . Each fitting is CNC-machined to exact tolerances and features precision-polished internal passages that allow turbulence-free water transfer .

Applications:

• Directs high-pressure water flow into the bottom section of the plunger housing in waterjet intensifier pumps 

• Connects low-pressure water supply or coolant return lines to the plunger housing assembly

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

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

• Compatible with major waterjet systems including KUNDA, KMT, FLOW, and OMAX 

Features:

• High-Strength Material: Manufactured from hardened stainless steel or nickel-chrome alloy for outstanding durability and corrosion resistance 

• 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) 

• Leak-Free Connection: Thread and sealing design ensures tight, vibration-resistant connection 

• OEM Compatibility: Fully compatible with KUNDA, KMT, FLOW, and OMAX 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
