High-Pressure Fluid Retention and Contamination Barriers for Demolition Hammers
The Hydraulic Breaker Seal Kit (precision-manufactured under OEM specification reference 3361 1400 11) is a critical fluid-power maintenance assembly engineered specifically for the Atlas Copco PB 310 series hydraulic hammer. Operating under relentless structural vibration and rapid pressure fluctuations, a rock breaker relies entirely on its sealing matrix to maintain maximum strike velocity and prevent internal pressure drops. This comprehensive repair kit replaces worn internal elastomeric elements, ensuring tight fluid containment between the high-speed piston and cylinder walls, which directly translates to sustained kinetic hitting force during intense concrete breaking and trenching operations.
MERIT seals are produced from high-performance polyurethane (PU), Hydrogenated Nitrile Butadiene Rubber (HNBR), and fluorocarbon compounds. These specialized materials are selected for their low compression set, exceptional resistance to high-frequency tearing, and outstanding thermal stability when subjected to high-temperature hydraulic fluids under continuous mechanical loads.
Technical Features and Material Excellence of MERIT Repair Kits
Surviving the aggressive hydraulic pressure spikes and preventing abrasive stone dust entry into the Atlas Copco PB 310cylinder requires engineered tolerances. MERIT delivers field reliability through:
1. Advanced Dual-Lip Dust Wiper Seals
The lower front head environment is constantly saturated with highly abrasive particulate matter. Our heavy-duty wiper profiles are designed to scrape the moving tool piston clean on every return stroke, preventing microscopic dust ingress that would otherwise score the cylinder walls and damage internal valve components.
2. High-Hardness PTFE Back-Up Rings
To counter extreme hydraulic spikes that occur during heavy breaking or accidental blank firing, our kits include premium polytetrafluoroethylene (PTFE) back-up rings. These rings provide vital anti-extrusion support to the primary rubber O-rings, ensuring they maintain their shape and sealing integrity under high operating pressures.
3. Thermal-Resistant Fluid Dynamic Seals
Continuous hammering generates localized thermal buildup in the hydraulic circuit. MERIT dynamic piston seals resist thermal degradation and hardening up to 120°C, maintaining their flexibility and preventing internal oil bypass, which ensures your breaker operates at peak structural efficiency all day long.
Primary Maintenance Applications
- Scheduled Interval Rebuilds: Complete replacement of vulnerable wear seals during standard 250 to 500-hour preventative maintenance cycles to prevent catastrophic field failures.
- Hydraulic Cylinder Resealing: Eliminating external oil leakage around the front head and restoring factory-standard hitting pressures in struggling or low-impact hammers.
- Emergency Fleet Repair: Rapid on-site servicing of plant hire equipment to resolve internal pressure drops and avoid expensive downtime on urban infrastructure projects.
