Seal Material: Oil-resistant Nitrile Butadiene Rubber (NBR), resistant to hydraulic oil corrosion
4. Operating Conditions & Replacement Standard
Function: Trap metal wear debris, rock dust and sludge in hydraulic oil to protect main pumps, multi-way valves and drilling impactors
Replacement Interval
Normal mining conditions: 2000 ~ 3000 operating hours
Heavy dust tunnel/quarry conditions: 1000 ~ 1500 operating hours, or replace immediately when differential pressure hits 0.35MPa
Structural Advantages: Multi-layer folded glass fiber, outer perforated protective screen and built-in support frame to resist hydraulic impact and prevent deformation or damage
