This heavy-duty accumulator diaphragm cup is specially developed for DAEMOS1800V hydraulic rock breakers, widely matched on medium & large excavator-mounted crushing equipment. It is the core energy storage sealing part of the breaker nitrogen accumulator, isolating hydraulic oil and high-pressure nitrogen completely.
Adopted imported modified HNBR + high-strength fiber composite material, the diaphragm cup features outstanding fatigue resistance, high pressure resistance, oil resistance and high temperature resistance. It thoroughly solves common faults including nitrogen leakage, striking force attenuation, abnormal impact and frequent failure of original diaphragm, greatly extending continuous working hours of breakers under high-frequency heavy impact conditions.

Fully fit DAEMOS1800V breaker accumulator cavity, consistent with OEM part numbers DAEMOS-1800V and DH18000071. No cutting, padding or modification required, direct replacement installation.
Core diaphragm body adopts imported modified HNBR with internal fiber reinforcement layer, excellent anti-fatigue performance. Resists hydraulic oil corrosion, high temperature aging and high-frequency stretching, keeps stable elasticity within -30°C ~ 135°C working environment.
All finished products pass 32MPa ultra-high pressure nitrogen sealing test. Effectively block nitrogen and hydraulic oil mutual leakage, maintain stable accumulator pressure, guarantee continuous and powerful striking force without power drop during long-time crushing operation.
Thickened curved transition edge and outer anti-tear reinforced ring design, avoid edge cracking, bulge and early damage under continuous high-frequency impact, effectively reduce maintenance frequency and equipment downtime cost.
Each diaphragm cup undergoes high-pressure air tightness, fatigue stretching, high temperature aging and dimensional calibration tests before delivery, fully meets OEM industrial standards for long-term stable heavy construction work.
Suitable for DAEMOS1800V hydraulic breakers equipped on various heavy-duty construction machinery:
