Multiquip EM517649 Motorized Flow Control Manifold Assembly

The Multiquip EM517649 Motorized Flow Control Manifold Assembly is a genuine OEM component designed for LS400, LS500, and LS600 series hydraulic-driven concrete pumps. Sourced directly through Multiquip's authorized parts program, EM517649 meets the exact specifications required by these Mayco pump models. This assembly integrates directly into the hydraulic control circuit of the pump, ensuring proper metering and directional regulation of hydraulic fluid to the pumping system. DHS Equipment stocks this part to help contractors get their concrete pump back up and running with a confirmed-fit OEM replacement.

Key Features

• Genuine OEM Hydraulic Precision — Built to Multiquip's exact tolerancing for motorized flow control in hydraulic concrete pump circuits, ensuring correct actuation response and fluid regulation.
• Direct-Fit Assembly — Designed to integrate into the existing hydraulic manifold circuit of LS400, LS500, and LS600 pumps without modification to surrounding hardware.
• Confirmed Fitment — Verified compatible with LS400, LS500, and LS600 Mayco hydraulic-driven concrete pump models.
• Sustained Output Consistency — A properly functioning flow control manifold maintains steady concrete output pressure and volume; a failed or worn unit can cause erratic pumping, pressure loss, or complete pump stoppage.
• Hydraulic System Integrity — As a critical component in the pump's hydraulic circuit, using a correctly rated OEM assembly helps prevent pressure imbalances that could stress downstream hydraulic components.

The motorized flow control manifold assembly regulates the flow and direction of hydraulic fluid within the concrete pump's drive circuit, allowing the machine to maintain consistent pumping pressure and output volume. An electrically actuated motor within the assembly adjusts the manifold valve position in response to operator commands or automatic system signals, giving precise control over the pump's delivery rate. When this assembly fails or degrades, operators typically experience inconsistent concrete output, loss of pressure control, or an inability to adjust pump speed — all of which can halt a pour mid-job.
