The Multiquip 100KDO7522 Suction Cover ST-4125 is a genuine OEM component designed for the ST-4125 concrete pump. Sourced directly from Multiquip, this cover is manufactured to the same specifications as the original part, ensuring a correct, trouble-free installation. Verified compatibility with the ST-4125 means you can order with confidence, knowing this part is the right match for your machine.
Key Features
- Genuine OEM Construction — Manufactured to original Multiquip specifications, ensuring the correct material thickness and sealing geometry for concrete pump suction-side service.
- Direct-Fit for ST-4125 — Engineered to mount directly to the suction inlet of the ST-4125 concrete pump with no rework or modification to the existing port assembly.
- Confirmed Fitment — Verified OEM fitment for the ST-4125 swing-tube concrete pump series.
- Suction Integrity Maintained — A properly seated suction cover keeps the inlet sealed and primed, supporting consistent pump prime and steady concrete flow through the delivery line.
- Durable for Demanding Pours — Built to withstand the abrasive, high-pressure environment of concrete pumping, resisting wear at the suction inlet where aggregate contact is constant.
The suction cover seals the inlet port on the concrete pump's hopper side, maintaining the negative pressure needed for the pump to draw material into the cylinders or swing-tube mechanism on each stroke. Without a properly functioning cover, the suction side loses its seal, causing prime loss, inconsistent material flow, and potential air entrainment in the concrete line. Replacing a worn or damaged cover promptly keeps the pump operating at full output and prevents downstream delivery issues on the pour.
