Multiquip EM16811 Shuttle Cylinder

The Multiquip EM16811 Shuttle Cylinder is a genuine OEM component designed for hydraulic-driven concrete pumps in the LS series, including the LS300, LS300P, LS300GK, LS300G, LS400, LS500, LS50TD, LS600, LS600P, LS40D, LS40TD, and LS60TD. As an authentic Multiquip replacement part, it meets the original build specification for your machine — ensuring the hydraulic pumping circuit operates exactly as intended. Sourced direct from Multiquip, the EM16811 is the correct part for operators and service technicians who need a dependable, drop-in solution for their LS series concrete pump.

Key Features

• Genuine OEM Hydraulic Integrity — Built to the same specification as the original, ensuring the shuttle cylinder delivers consistent hydraulic pressure cycling without bypass or pressure loss.
• Direct Replacement for LS Series Pumps — Installs in the same hydraulic circuit position as the original unit, with matching port sizing and mounting configuration for the LS series platform.
• Broad LS Series Compatibility — Confirmed fitment across LS300, LS300P, LS300GK, LS300G, LS400, LS500, LS50TD, LS600, LS600P, LS40D, LS40TD, and LS60TD concrete pumps.
• Sustained Pumping Output — A correctly functioning shuttle cylinder maintains the alternating hydraulic stroke that keeps concrete moving through the line; a worn or failed cylinder causes erratic output or complete pump stoppage.
• Hydraulic System Safety — Proper shuttle cylinder function is critical to maintaining controlled pressure within the hydraulic circuit — a failed unit can cause uncontrolled pressure fluctuation that stresses downstream components.

The shuttle cylinder is the hydraulic component responsible for directing fluid flow to alternate between the two concrete pumping pistons inside an LS series concrete pump. It acts as a directional control valve within the hydraulic circuit, triggering each piston stroke in sequence to produce a steady, continuous flow of concrete through the delivery line. When the shuttle cylinder wears or fails, the pump loses the ability to alternate strokes correctly — resulting in pulsating output, reduced throughput, or a complete loss of pumping function until the part is replaced.
