roduct ID: 05045497 – Hydraulic Pressure Gauge (SL-IV & SL-V Series)

Description:
This component is a hydraulic pressure gauge, specifically designed for use on SL-IV and SL-V series waterjet intensifier pumps . It is a precision measurement instrument that displays the hydraulic system pressure, which is used to monitor the low-pressure hydraulic oil side of the intensifier. The gauge features a stainless steel case, safety glass, and glycerine filling, which dampens pointer vibration caused by pressure fluctuations in the hydraulic circuit .

The dial plate displays pressure in both bar and psi units, allowing operators to monitor system pressure in either measurement standard . This is an OEM replacement part for waterjet cutting systems.

Applications:

• Used on SL-IV and SL-V series waterjet intensifier pumps to monitor hydraulic oil pressure 

• Installed on the hydraulic power unit or intensifier manifold, typically in line with the hydraulic pump outlet or control valve block

• Enables operators to verify proper hydraulic system pressure for optimal intensifier performance

• Assists in troubleshooting pressure-related issues, including pump cycling abnormalities and insufficient cutting pressure

Features:

• Dual Scale Display: Dial plate calibrated in both bar and psi units for convenient pressure reading in either measurement standard 

• Stainless Steel Case: Corrosion-resistant housing suitable for harsh waterjet operating environments 

• Glycerine Filled: Dampens pointer vibration and pulsation from hydraulic pressure fluctuations, providing stable, readable gauge indications 

• Safety Glass: Protective window that withstands pressure spikes and provides operator protection in case of internal gauge failure 

• OEM Specification: Direct replacement part for SL-IV and SL-V series intensifier pumps 

Maintenance:

• Visual Inspection: Periodically inspect the gauge case and lens for signs of corrosion, cracking, or fluid leakage (glycerine seepage indicates seal failure)

• Zero Check: With the hydraulic pump off and system pressure fully bled, verify the gauge needle returns to zero. A gauge that does not zero accurately requires replacement

• Cleaning: Wipe the gauge exterior with a soft, damp cloth to remove hydraulic oil residue or abrasive dust; avoid using solvents that may damage the lens or case finish

• Replacement Criteria: Replace the gauge if the lens is cracked, the case is corroded or damaged, the needle is bent or sticking, or if pressure readings are inconsistent with known system behavior

• Pressure Verification: If gauge readings are suspect, verify against a calibrated master gauge during scheduled maintenance to ensure accuracy

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

• Thread Sealant: When installing a replacement gauge, apply appropriate thread sealant to the connection threads to prevent hydraulic fluid leaks

• Cross-Reference Information: This is an OEM replacement part for SL-IV and SL-V series pumps . Verify compatibility with your specific intensifier model before installation
