Product ID: 05147913 – Hydraulic Cylinder Head (Intensifier Pump Component)

Description:
This component is a hydraulic cylinder head, designed as the end closure for the hydraulic cylinder in high-pressure waterjet intensifier pumps . It is a precision-machined stainless steel cap that bolts onto the end of the hydraulic cylinder body, sealing the hydraulic fluid circuit while providing a mounting interface for the high-pressure cylinder assembly . The cylinder head contains internal ports and passages for directing hydraulic oil flow to drive the reciprocating piston. It is engineered for use with 0.88 inch (7/8") plunger block systems rated at 60,000 PSI (approximately 4,137 bar) .

Alternative OEM part numbers include 05034772, 1-12563, and 5000087 .

Applications:

• Used as the hydraulic end closure on waterjet intensifier pumps, specifically SL-IV and SL-V series models .

• Installed at the hydraulic oil side of the intensifier assembly, connecting the hydraulic cylinder body to the high-pressure cylinder and sealing head.

• Provides the mounting surface for tie rods or mounting stems that secure the complete intensifier stack.

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

Features:

• Stainless Steel Construction: Manufactured from corrosion-resistant stainless steel to withstand exposure to hydraulic fluids and moisture in waterjet environments .

• Precision-Machined Surfaces: Features precision-ground sealing surfaces and O-ring grooves to ensure leak-free operation between the cylinder head, cylinder body, and high-pressure components.

• Integrated Fluid Porting: Contains internal passages for directing hydraulic oil flow to drive the intensifier piston.

• High-Strength Design: Engineered to withstand extreme pressure cycling from the hydraulic system without deformation or fatigue failure.

• Direct Replacement: Designed as a drop-in replacement for SL-IV and SL-V series intensifier pumps, compatible with OEM specifications.

Maintenance:

• Inspection: During pump overhaul, inspect the cylinder head for signs of cracking, corrosion, pitting, or sealing surface damage. Pay particular attention to O-ring grooves and mounting bolt holes.

• Leak Diagnosis: Hydraulic oil leakage from the cylinder head area typically indicates worn seals or O-rings on the cylinder head interface . Inspect and replace seals immediately.

• Seal Replacement: Always replace all O-rings, backup rings, and sealing elements associated with the cylinder head during each service. Do not reuse old seals.

• Torque Compliance: When reinstalling, tighten all mounting bolts or retaining screws to the specific torque values listed in the equipment service manual. Use a staggered (cross) tightening pattern to ensure even clamping force distribution.

• Thread Lubrication: Apply manufacturer-recommended anti-seize compound or thread lubricant to all threads during reassembly to prevent galling and ensure accurate torque application.

• Surface Preparation: Before installation, ensure the cylinder head sealing surfaces and mating cylinder body surfaces are clean, dry, and free from debris, old sealant, or corrosion.

• Full Depressurization: Always fully depressurize both the hydraulic system and the high-pressure water system before removing or installing the hydraulic cylinder head. Follow lockout/tagout procedures.

• Replacement Criteria: Replace the cylinder head if cracks, severe corrosion, thread damage, or sealing surface damage is detected. Do not attempt to repair a cracked or severely damaged cylinder head.

• Professional Assistance: If leakage persists after seal replacement, consult a qualified waterjet service technician to inspect for cylinder head warpage or damage .
