Understanding the Hydraulic Seal Kit

A Seal Kit, such as the 55201997 for Sandvik machinery, is fundamental to the function of hydraulic systems. These kits contain various seals (O-rings, rod seals, piston seals, etc.) made from materials like Nitrile (NBR), Polyurethane (PU), or PTFE, selected for their resistance to high pressure, temperature, and hydraulic fluids. The primary role of these seals is to prevent internal and external fluid leakage, maintain the necessary pressure for hydraulic actuation, and protect critical moving parts from contaminants. Regular replacement of the hydraulic seal kit is a key part of preventative maintenance for drilling equipment and rock drilling machinery to avoid costly system failure. Our Hugeminer OEM replacement parts are designed for a perfect fit and reliable performance in demanding mining environments.

Drilling Equipment Troubleshooting: Sandvik DD321

Fault: Loss of Hydraulic Pressure in the boom or feed system of a Sandvik DD321 face drilling jumbo. This often leads to sluggish movement, drifting, or an inability to hold a load.

Cause: One of the most common causes is **internal leakage** within hydraulic cylinders, typically due to **worn or damaged seals**. This breakdown allows hydraulic fluid to bypass the piston or rod, directly impacting the system's ability to maintain pressure. The degradation of components like the Seal Kit, 55201997, is a key factor.

Solution:

1. Identify the leaking cylinder through visual inspection or pressure testing.

2. Safely depressurize and remove the affected cylinder.

3. Disassemble the cylinder and thoroughly clean all components.

4. Install a high-quality replacement Seal Kit, such as our 55201997, ensuring all seals are correctly seated.

5. Reinstall, bleed the system of air, and test the cylinder's function. Using genuine quality Epiroc Parts or Atlas Parts is also recommended for related components.
