Productum Overview

This heavy-duty accumulator piston cup diaphragma is specially engineered for Etc. DNB30-L hydraulic rock breakers widely fitted on medium excavators and engineering demolition machinery. It serves as the core energy storage sealing component, isolating high-pressure nitrogen and hydraulic oil inside the accumulator. Made of imported high-performance modified PPDI reinforced elastomer, it delivers outstanding fatigue resistance, oil resistance and high-low temperature stability. It fully replaces original Etc. OEM diaphragm parts, solves common faults such as nitrogen leakage, impact force attenuation and abnormal hammering, and extends the continuous working life of the breaker under long-term heavy crushing operations.

Claves Venditionis Puncta

1. 100% OEM Exact Replacement. Fully matched with original Etc. DNB30-L hydraulic breakers, consistent with OEM part numbers ETC-DNB30-L and DH3008612. Standard dimensional tolerance, no cutting or modification required for direct replacement installation.

2. Premium Imported Reinforced PPDI Material. Core diaphragm body adopts high-strength modified PPDI composite material with built-in fiber reinforcement layer. Excellent anti-fatigue stretching performance, resistant to hydraulic oil corrosion, aging and high-frequency cyclic deformation, stable operation at -30°C to 130°C harsh working environment.

3. Zero Nitrogen Leakage & Stable Impact Power. Every finished diaphragm undergoes 22.0 MPa high-pressure air tightness cycling test. Effectively blocks nitrogen-oil mixing leakage, maintains stable accumulator energy storage efficiency, guarantees consistent breaker impact force and avoids weak hammer, intermittent striking failure.

4. Set completus accessoriorum ad reparationem integratam. Equipatus omnibus partibus de sigillando congruentibus quae ad totam renovationem accumulatoris requiruntur, solutio unica pro manutenentia, breviorem tempus in quo machinae in loco non operantur facit et pretium totale manutenentiae machinarum minuit.

5. Strictissima inspectio fabricae completa. Unaquaeque copia cinguli pistonicis diafragmata testibus fatigationis tractionis, testibus aetationis ad temperaturas altas et bassas, et testibus sigillationis ad pressionem altam antequam mittatur, plene normas fabricatoris originalis (OEM) implet, praebens operationem constructionis stabilem et fidedignam per tempus longum.

6. Lata applicatio. Idoneus pro frangibribus hydraulicis DNB30-L, qui in variis machinis constructionis gravioribus installantur:

• Excavatoribus mediis (Sany 135, XCMG 150, Lovol 140, Liugong 130) • Onibus cum frangibribus • Machinis municipalibus demolitionis • Machinis frangendis in lapidicis et in metalliferis • Machinis frangendis concreti in restructione viarum • Machinis frangibilibus hydraulicis mobilibus gravioribus
