Multiquip EM517649 Manifold with Motorized Flow Control - OEM Replacement Part

The manifold with motorized flow control regulates hydraulic fluid distribution throughout the concrete pump's hydraulic system, enabling precise control of pumping speed and concrete flow volume. This critical hydraulic component integrates with the LS400/LS500 series control system, working in conjunction with the volume control switches (flow increase/decrease) visible on the operator control panel to adjust pumping rates in real-time during concrete placement operations.

This manifold assembly routes pressurized hydraulic oil from the pump through designated circuits (STA-1 and STA-2 positions) to the main concrete cylinders, shuttle tube hydraulics, and optional agitator/outrigger systems. The motorized flow control responds to operator input from the control panel, modulating flow to achieve the desired strokes per minute (displayed as STROKES/MIN and YDS/HR on the LCD screen). Proper manifold function is essential for maintaining system pressure regulation (working alongside 1000 PSI and 4400 PSI relief valves) and ensuring synchronized operation of the hydraulic cylinders that drive concrete displacement.

Compatible with the following Multiquip concrete pump models:

• LS400/LS500
• LS450
