31E3-3187 Accumulator for Hyundai excavators R140W-9 R170W-7 R180W-9 R210W-9 and Case E18C CX37C
The 31E3-3187 Hydraulic Accumulator is a premium diaphragm-type accumulator engineered for Hyundai wheeled excavators (R140W-9/R170W-7/R180W-9/R210W-9) and Case mini-excavators (E18C/CX37C). It stabilizes hydraulic system pressure, absorbs shock waves, and stores energy for peak-demand operations, preventing component fatigue and extending service life in high-vibration construction environments.
Key Features
· OEM-Matched Precision: 0.35L volume, 31.5MPa max working pressure, and diaphragm design for consistent pressure regulation and energy storage.
· High-Strength Construction: Carbon steel body with anti-corrosion coating and reinforced crimped end caps for 10,000+ hours service in harsh conditions.
· Leak-Proof & Shock-Absorbent: Nitrile rubber diaphragm and O-ring seals eliminate fluid leakage; absorbs pressure spikes up to 42MPa to protect valves/pumps.
· Plug-and-Play Fit: Direct bolt-on mounting with 3/4" NPT port; no modification needed for Hyundai/Case excavator installation.
Compatible Equipment
· Excavators: Hyundai R140W-9, R170W-7, R180W-9, R210W-9; Case E18C, CX37C; also fits Hyundai R200W-7, R170W-9.
