The HNBR Difference
Our SAGA series diaphragms are manufactured using Hydrogenated Nitrile Butadiene Rubber (HNBR). Standard NBR membranes often become brittle and crack due to the nitrogen heat spikes and oil pulsation. Our HNBR formula maintains its tensile elasticity at temperatures up to 210°C, ensuring zero nitrogen migration into the hydraulic oil, which maintains the consistent impact energy of your SAGA breaker.
| Model | Compatible Breaker | Outer Diameter (Approx) | Material Grade | Application |
|---|---|---|---|---|
| SAGA 200 | MSB SAGA 200 / 210 | ~125 mm | HNBR Premium | 18-22 Ton Excavators |
| SAGA 300 | MSB SAGA 300 / 310 | ~145 mm | HNBR Premium | 25-30 Ton Excavators |
| SAGA 350 | MSB SAGA 350 / 400 | ~165 mm | HNBR + PTFE Coat | 33-40 Ton Excavators |
3 Signs of Diaphragm Failure (Value Hook)
Striking Force Drop: A sudden decrease in impact power often means nitrogen pressure is leaking through a micro-tear in the diaphragm.
Hydraulic Hose Vibration: Unusual “jumping” of high-pressure hoses indicates the accumulator is no longer absorbing pressure spikes.
Oil Foaming: Bubbles in the hydraulic return line often confirm nitrogen is migrating into the oil circuit through the membrane.
As a leading hydraulic breaker diaphragm manufacturer, we supply high-performance, durable replacement diaphragms specifically engineered for SAGA200, SAGA300, and SAGA350 models.
Our diaphragms are manufactured to OEM standards, ensuring perfect fit, superior pressure resistance, and extended service life for your breaking equipment. We understand that downtime costs you money, which is why we focus on reliability and consistent performance.
