Key Features
- Genuine OEM Construction — Manufactured to Multiquip's exact hydraulic tolerances, ensuring the cartridge seats, seals, and cycles precisely as the original unit did.
- Direct Cartridge Replacement — Designed as a drop-in assembly for the accumulator housing on compatible LS-series concrete pumps, allowing straightforward installation without custom fitting.
- Broad LS-Series Fitment — Confirmed for LS40D, LS40TD, LS50TD, LS60TD, LS400, LS500, and LS600 hydraulic concrete pump models.
- Maintains Consistent Output Pressure — A correctly functioning accumulator unloader cartridge keeps hydraulic pressure regulated and delivery strokes smooth, protecting the pump circuit from pressure spikes.
- Hydraulic System Safety — The unloader function is critical for safe depressurization of the hydraulic circuit during servicing; a worn or failed cartridge can result in uncontrolled pressure buildup.
The accumulator unloader cartridge assembly is a precision hydraulic component that regulates and relieves pressure within the accumulator circuit of a hydraulic-driven concrete pump. Its primary job is to maintain a stable working pressure and allow the system to safely unload when demand drops or the pump is shut down — without this component functioning correctly, the hydraulic circuit can experience pressure surges that accelerate wear on seals, hoses, and valves throughout the pump. When the cartridge wears or fails, operators typically notice erratic pumping strokes, pressure fluctuations, or an inability to safely depressurize the system for maintenance.
