High-Pressure Fluid Containment Matrix for 26-to-40-Ton Carrier Excavators

The Hydraulic Breaker Seal Kit (locally known in the Adriatic region as Brtve za pikhamer, Garnitura brtvi, or Set brtvila) is the critical fluid-containment and pressure-isolation matrix custom-compounded for heavy-duty Rammer 3288, 3288E, and Sandvik BR3288 large-range hydraulic rock breakers. Tasked with managing severe hydraulic operating pressure variations inside a massive 2.4-ton hammer assembly, this premium sealing group acts as a high-performance equivalent to the original equipment manufacturing standards.

Positioned across the main distributor valve block, high-pressure accumulator mounting faces, and the central reciprocating piston cylinder sleeve, these seals prevent critical oil bypass. This ensures that 100% of the carrier excavator’s oil flow is efficiently directed into driving the striking piston, maximizing impact velocity in hard limestone, concrete demolition, and infrastructure trenching.

MERIT manufactures this elite replacement seal group using a multi-material configuration engineered to withstand sustained operational oil temperatures up to 110°C and intense continuous friction cycles without cracking, hardening, or tearing.

Technical Features and Material Engineering of MERIT BR3288 Sealing Kits

Surviving continuous exposure to intense high-frequency hydraulic shockwaves and preventing external oil leaks in demanding heavy-quarry environments requires absolute chemical and dimensional precision. MERIT ensures field reliability through:

1. Bronze-Filled PTFE Dynamic Step Seals

The primary dynamic piston rod seals are composed of premium PTFE (Teflon) filled with Bronze paired with high-elasticity Fluorocarbon (FKM/Viton) square energy expanders. This advanced engineering design limits stick-slip friction on the reciprocating piston shank, eliminating cold scuffing while maintaining an absolute fluid barrier under high pressures.

2. Heavy-Duty Polyurethane (PU) U-Cups & Wipers

Our specialized dual-lip polyurethane dust wipers and rod seals form a strict protective barrier at the front head tool interface. They aggressively reject abrasive rock dust, concrete slurry, and environmental moisture ingress while securely containing the internal oil circuit to eliminate high-pressure blow-by.

3. High-Durometer Anti-Extrusion O-Rings

Static sealing surfaces utilize 90 Shore A hardness Nitrile (NBR) O-rings reinforced with contoured thermoplastic back-up rings. This multi-layered defense prevents seal extrusion, flattening, or clipping across structural block gaps, valve housings, and main pressure points during intense hydraulic rebound peaks.

Primary Overhaul Applications

• Complete Power Cell Rebuilds: Restoring factory-standard pressure isolation during comprehensive mid-life hammer servicing and cylinder refurnishing.
• Preventative Leak Mitigation: Replacing degraded, heat-hardened elastomer groups before external fluid loss causes excessive oil consumption or environmental site contamination.
• Volumetric Efficiency Restoration: Swapping worn dynamic rings to correct low impact frequency, tool drifting, or sudden drops in rock-breaking velocity.
