Productum Overview

This heavy-duty replacement cup- diaphragma peculiariter est constructus pro Sandvik HE119 and HE122 hydraulic rock drifters. It serves as the core accumulator sealing component for impact energy buffering. The product adopts high-strength fabric-reinforced FKM composite rubber material, delivering outstanding anti-fatigue, impact-resistant, oil-resistant and wear-resistant performance. It perfectly replaces original Sandvik OEM diafragmata , solves common failures such as accumulator pressure loss, diaphragm rupture and internal leakage, stabilizes drilling impact performance and extends service life under continuous high-intensity rock-drilling working conditions 。

Claves Venditionis Puncta

1. 100% Exact OEM Replacement.

Fully dimensionally compatible with original Sandvik HE119 / HE122 rock drifters, matches OEM part numbers 14079818 and 14080178. No extra machining required for direct field installation 。

2. High-Strength Fabric-Reinforced Diaphragm Material.

Core sealing body uses fabric-reinforced high-performance FKM composite rubber. Excellent fatigue-resistance against frequent impact pulsation, oil-proof and aging-resistant, stable operation within -25°C ~ 110°C working range 。

3. Anti-Burst & Stable Pressure Holding Performance.

Omnis diafragma subicitur testibus fatigationis pulsantis et pressionis rupturae usque ad 28 MPa. Efficebat praeventionem decrementi pressionis accumulatoris et rupturae subitae, servat potestatem stabilis impactus perforatoris petrae, evitat decrementum potestatis perforationis et cessationem anormalem machinae.

4. Pars reservata nucleus unius unitatis, formata cum praecisione.

Sequere stricte designum originale contorni cavitatis. Arcus transitus optimizatus minuit concentrationem stress sub oneribus impactus repetitis. Facilis substitutio in loco, breviat tempus inactivitatis pro manutenentia apparatus et minuit impensas operationis in mine.

5. Strictum controllem qualitatis in fabrica.

Omnis cup‑diafragma transit testes fatigationis pulsantis, retentionis pressionis et aetatis ante expeditionem. Convenit normis OEM dimensionum et performance, garantit operationem fidelem longi temporis in ambientes mineralium asperos.

6. Orbis Applicationis.
