Productum Overview

This heavy-duty accumulator leather cup and diaphragma assembly is specially developed for Etc. DNB50-HIGH hydraulic rock breakers, widely matched on 5–8 ton excavators for construction demolition, rock crushing and mining operations. It integrates integrated leather cup and high-strength rubber diaphragm as one core energy storage sealing part, fully replacing original OEM spare parts.

Adopted imported reinforced PPDI composite rubber + high tensile leather composite material, the product features outstanding nitrogen isolation, high-frequency fatigue resistance, oil resistance and wide temperature adaptability. It effectively solves common failures including nitrogen leakage, weak impact force, frequent energy loss and diaphragm rupture, greatly extending continuous working hours of the breaker under heavy-duty high-frequency impact conditions.

Claves Venditionis Puncta

1. 100% OEM Precise Replacement. Fully dimensional matched with original Etc. DNB50-HIGH breaker accumulator, corresponds to OEM part numbers DNB50-HIGH-ACC01 and 320061198. Direct plug-and-play installation without cutting or modification.

2. Premium Composite Wear-resistant Material. Core diaphragm adopts high-performance PPDI fluororubber compound with thickened leather reinforcement layer, ultra-high tear resistance and anti-fatigue performance. Stable operation under -30°C ~ 150°C continuous high-temperature hydraulic oil soaking, no hardening, cracking or elastic attenuation.

3. Zero Nitrogen Leakage & Stable Impact Output. Omnes coniunctiones strictissimum 18 MPa nitrogenii alti pressionis testem hermeticitatis superant. Perfecte separat oleum hydraulicum et cameram nitrogenii, conservat constantem pressionem accumulatoris, vitat impactionem debilem et intermissam, servat potentiam constans frangendi pro operatione diuturna.

4. Integrum Omnium-in-Unum Reparationis Coniunctionem. Completa congruentia inter cypellam coriaceam + diafragmam + accessoria sigillandi auxiliaria in uno set, substitutio unica pro reparatione completa accumulatoris, multum breviatur tempus manutenctionis in loco et minuuntur impensae pro temporibus non operativis machinae.

5. Stricta Inspectio Plurium Rotarum in Fabrica. Quisque productus finitus subicitur testibus: aeris hermeticitatis, fatigationis cyclicae altae frequentiae, aetationis altae temperaturae et rupturae pressionis antequam admittatur, plene satisfacit normis productionis OEM, usus industrialis diuturnus stabilis et fidelis.

6. Lata Sphera Applicationum. Congruit cum frangendis hydraulicis DNB50-HIGH, quae montantur in variis machinis technicis:

• Excavatores minores 5–8 ton (Sany 55/60, XCMG 60, Lovol 60, Liugong 60) • Onusti retroexcavatores parvi • Apparatus demolitorius municipalis • Machinae frangendae petrarum secundariae in lapidicinis et mineis • Apparatus frangendi concreti in restructione viarum • Machinae fracturae hydraulicae mobilis robustae
