Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original pressure and flexibility ratings for hydraulic accumulator circuits, not a generic substitute.
- Direct-Fit Replacement — Engineered to match the original hose routing, end fittings, and length of the ST-45HRM and ST-70 accumulator system for a straightforward swap.
- Confirmed Fitment — Verified for ST-45HRM and ST-70 swing tube concrete pump models; always cross-reference your part number before ordering.
- Sustained Pumping Pressure — A correctly functioning accumulator hose maintains consistent hydraulic pressure in the system, supporting smooth, uninterrupted concrete delivery cycles.
- Hydraulic System Integrity — A cracked or degraded accumulator hose can cause pressure loss, erratic pump cycling, and potential hydraulic fluid leakage — replacing it promptly protects the broader hydraulic circuit.
The accumulator hose connects the hydraulic accumulator to the pump's hydraulic circuit, allowing the accumulator to absorb and release pressure during each stroke cycle. This dampens pressure spikes and keeps the pumping action smooth and consistent. When the hose deteriorates — through cracking, swelling, or fitting failure — the accumulator can no longer regulate pressure effectively, leading to uneven output, increased wear on hydraulic components, and potential fluid loss.
