Multiquip EM20731 Control Chain

The Multiquip EM20731 is a genuine OEM Control Chain designed for the C30HD concrete pump. As a factory-original component, this chain is manufactured to the same specifications as the part it replaces, ensuring a consistent, dependable fit within the pump's control mechanism. Verify your model code against C30HD equipment before ordering to confirm compatibility.

Key Features

• OEM-Grade Chain Construction — Manufactured to the original link pitch, tensile strength, and material spec required by the C30HD control system, not a generic chain adapted to fit.
• Direct-Fit Replacement — Connects to existing anchor points and sprocket interfaces on C30HD units without modification to mounting hardware or chain length.
• Confirmed C30HD Fitment — Sourced and verified for the Multiquip C30HD concrete pump; use your model code to confirm before ordering.
• Control System Integrity — A worn or stretched control chain leads to imprecise valve timing and inconsistent pump output; replacing it restores accurate mechanical control over pump cycling.
• Genuine Multiquip OEM Part — Supplied by DHS Equipment as an authorized Multiquip OEM part, backed by traceability to the original manufacturer's part number EM20731.

The control chain on a cycloidal concrete pump like the C30HD transmits mechanical movement to regulate the timing and sequencing of the pump's valve or piston action. It acts as the link between the drive mechanism and the control components that govern how concrete is pushed through the system. When this chain stretches, wears, or fails, pump output becomes erratic and the machine loses the precise cycling needed to move concrete efficiently — making timely replacement essential to keeping pours on schedule.
