The Multiquip EM14818 Ball 4" is a genuine OEM replacement designed for the C30HD series cycloidal concrete pumps, including the C30HD, C30HDG, C30HDGA, C30HDN, C30HDNI, and C30HDZ models. As an authorized Multiquip parts source, DHS Equipment supplies this component direct from the OEM supply chain, so you receive the exact part engineered for your machine. The EM14818 matches the original dimensional and material specifications required by the C30HD pump family, ensuring a correct installation without modification. If your concrete pump is showing flow inconsistency or valve-related wear, replacing the 4" ball with the correct OEM part is the reliable path back to full operation.
Key Features
- OEM-Grade Material and Dimensional Accuracy — Manufactured to the precise diameter and surface finish tolerances required for proper sealing and valve function inside a cycloidal concrete pump.
- Direct-Fit Replacement for C30HD Series Pumps — Engineered to drop into the existing valve assembly on C30HD, C30HDNI, C30HDGA, C30HDG, C30HDN, and C30HDZ concrete pumps without reworking the housing or seat.
- Genuine Multiquip OEM Part — Sourced through the authorized Multiquip supply chain; part number EM14818 is the factory-designated ball component for these pump models.
- Maintains Consistent Concrete Flow — A properly seated 4" ball controls the direction and pressure of concrete through the pump circuit; wear or failure causes pressure loss, backflow, or erratic discharge.
- Pressure-Rated for Concrete Pump Duty — Built to withstand the cyclic hydraulic pressure loads and abrasive slurry conditions specific to cycloidal concrete pump valve assemblies.
The 4" ball in a cycloidal concrete pump serves as the primary check-valve element, controlling the one-directional flow of concrete through the pump's suction and discharge circuit. As the pump cycles, the ball seats and unseats against a machined valve seat to prevent backflow and maintain pumping pressure. When the ball wears, becomes pitted from abrasive aggregate, or fails to seat properly, the pump loses prime, output pressure drops, and concrete delivery becomes inconsistent — all of which interrupt the pour and add time to the job. Replacing the ball with the correct OEM-spec EM14818 restores proper valve action and gets the pump back to rated output.
