Productum Overview

Hoc accumulatōrium robustum diaphragma & leather cup assembly is specially developed for D&A 252B hydraulic rock breakers, widely matched on medium excavator demolition machinery. It is the core energy storage sealing part of the breaker nitrogen accumulator, isolating high-pressure nitrogen and hydraulic oil completely. Manufactured with imported reinforced FKM fluororubber + high-toughness fabric-reinforced leather composite material, it features outstanding fatigue resistance, high pressure resistance and oil aging resistance. It directly replaces original D&A spare parts, solves common faults such as nitrogen leakage, insufficient impact force and rapid pressure attenuation, and greatly extends continuous working life of the breaker under frequent high-frequency impact operations.

Claves Venditionis Puncta

1. 100% OEM Direct Replacement. Perfect dimensional matching for original D&A 252B breaker, consistent with OEM part numbers DA-252B and 3072116892. No cutting, grinding or modification required for quick on-site installation.
2. High-strength Composite Sealing Material. Core diaphragm adopts thickened FKM fluororubber with fabric reinforcement layer; leather cup uses wear-resistant oil-proof composite leather. Anti-fatigue stretching, resistant to hydraulic oil corrosion and high-temperature aging, stable performance between -25°C and 115°C.
3. Zero Nitrogen Leakage & Stable Impact Output. Omnes producta perfecta transirent testum cycli faticae hermeticitatis sub alta pressione 22,0 MPa. Evitant efficaciter perditum nitrogenii et decrementum pressionis, servant energiam impactus constans frangentis, eliminant ictus infirmos et molestias frequentis replectionis nitrogenii.
4. Integra Assemblage Reparationis Completa. Continet omnes accessoria hermetica congruentia ad revisionem accumulantis. Set integrum unius partis breviat tempus inactivitatis pro manutenzione et minuit costum operationis & manutenctionis totius apparatus.
5. Stricta Inspectio Qualitatis Fabricae Multistadium. Omnis diaphragma & copula corii subicitur testis fatigationis tractionis, hermeticitatis sub alta pressione, et aetationis thermalis antequam tradatur; plene satisfacit normis productionis OEM, stabilis et fidabilis ad usum constructionis gravis longo tempore.
6. Latus Campum Applicationis. Idoneus pro frangentibus petrarum hydraulicis D&A 252B montatis in variis machinis ingeniariis gravibus:
