The Multiquip EM97004 Heavy Duty Coil ST40 is a genuine OEM component designed for the ST40 swing tube concrete pump. As a direct OEM replacement, this coil is manufactured to the same specifications as the original, ensuring correct electrical output and a drop-in installation on ST40 equipment. Sourced directly through Multiquip's authorized parts channel, the part is the right call when you need a coil that performs exactly as the machine demands.
Key Features
- OEM-Matched Coil Winding Spec — Built to the same winding resistance and output rating as the original ST40 coil, ensuring proper voltage and magnetic force characteristics.
- Direct-Fit Installation — Engineered to mount directly to the ST40 solenoid valve assembly with no rework or adaptation to existing connectors or hardware.
- ST40 Concrete Pump Fitment — Specifically validated for the Multiquip ST40 swing tube concrete pump series.
- Heavy Duty Construction — Wound and encapsulated to withstand the demanding duty cycles and environmental conditions common to concrete pumping operations.
- Consistent Solenoid Valve Actuation — A correctly functioning coil ensures the solenoid valve responds precisely, maintaining proper hydraulic or pneumatic cycling in the pump circuit. A failed coil leads to erratic valve behavior or complete loss of actuation.
A solenoid coil generates the electromagnetic field that opens or closes a solenoid valve by pulling in a plunger when energized. In a concrete pump like the ST40, this valve controls the flow of hydraulic fluid or air that drives key operational functions within the pumping circuit. When a coil fails — through burnout, a broken winding, or moisture ingress — the valve it controls stops responding, which can halt pump operation entirely or cause unpredictable cycling. Replacing a worn coil with the correct OEM part restores precise, consistent valve actuation and gets the machine back to full output.
