The Multiquip EM14419 Piston Cup is a genuine OEM replacement designed for the C30HD concrete pump. Sourced directly from Multiquip, this piston cup meets the original engineering specifications for the C30HD, ensuring a correct, reliable fit in the pumping cylinder. Whether you're performing scheduled maintenance or replacing a worn seal, the part is the factory-correct choice to restore full pumping performance.
Key Features
- OEM-Grade Seal Material — Manufactured to the original compound and durometer specification, delivering the compression performance and chemical resistance required in concrete pump cylinder applications.
- Drop-In Cylinder Fit — Engineered to the exact bore diameter and lip profile of the C30HD pumping cylinder, seating correctly without machining or shimming.
- Confirmed C30HD Fitment — Verified OEM replacement for Mayco C30HD concrete pump models.
- Consistent Output Pressure — A correctly seated piston cup maintains the seal between the piston and cylinder wall, allowing the pump to build and sustain the pressure needed for continuous concrete delivery.
- Genuine OEM Part — Carries the Multiquip part number EM14419, ensuring you receive the correct specification part with full OEM traceability.
The piston cup is a flexible sealing element that fits around the piston head inside the pump cylinder. It forms a pressure-tight seal against the cylinder wall, allowing the piston's back-and-forth stroke to draw concrete in and push it through the discharge line under consistent pressure. When a piston cup wears, cracks, or loses its sealing lip, the pump loses prime, output pressure drops, and concrete delivery becomes inconsistent or stops altogether — making timely replacement essential to keeping production on schedule.
