The Multiquip EM20711 Solenoid Spring is a genuine OEM component designed for the C30HD concrete pump. As a direct OEM part sourced through Multiquip's authorized supply chain, it is manufactured to the exact specifications of the original, ensuring proper solenoid operation and system reliability. This spring is a critical small component that supports correct solenoid function in the hydraulic or fuel control circuit of the C30HD, making it an important part to replace at the first sign of wear or failure. DHS Equipment supplies this part as a verified OEM replacement so you can get your machine back to work with confidence.
Key Features
- OEM Spring Tension Specification — Manufactured to the exact tension and dimensional spec of the original, ensuring the solenoid engages and releases with the correct force every cycle.
- Drop-In Installation — Designed to seat directly into the solenoid assembly on the C30HD without modification, maintaining correct spring travel and seating depth.
- C30HD Concrete Pump Fitment — Confirmed fitment for the Multiquip C30HD cycloidal-drive concrete pump series.
- Sustained Solenoid Response — A correctly tensioned spring maintains consistent solenoid actuation, preventing erratic on/off behavior that can disrupt concrete pump output and flow control.
- Fuel and Hydraulic System Safety — In solenoid-controlled fuel shutoff or hydraulic valve applications, a fatigued or broken spring can prevent proper shutoff — replacing it with an OEM-spec part restores safe, predictable system control.
The solenoid spring is a small but essential component within the solenoid assembly, providing the return force that snaps the solenoid plunger back to its resting position once the electrical signal is removed. Without adequate spring tension, the solenoid may stick open or fail to fully close, leading to loss of control over fuel flow, hydraulic pressure, or electrical switching — depending on the circuit it serves. On a concrete pump like the C30HD, where consistent output and controlled shutoff are critical, a worn or broken solenoid spring can cause unpredictable operation or prevent the machine from shutting down cleanly.
