The Multiquip EM97008 is a genuine OEM Unloading Valve Cartridge designed for the ST-45HRM and ST-70 concrete pump models. As a direct OEM replacement, EM97008 is built to the same specifications as the original component, ensuring correct fitment and consistent hydraulic performance in the field. Sourced directly through Multiquip's authorized parts network, this cartridge is the right call when your ST-series pump needs a hydraulic system service or repair.
Key Features
- Genuine OEM Hydraulic Specification — Manufactured to exact flow and pressure ratings for the unloading valve circuit, ensuring the hydraulic system operates within its designed parameters.
- Direct Cartridge Replacement — Drops into the existing valve body on ST-series concrete pumps without additional machining or adaptation to the housing.
- Confirmed ST-Series Fitment — Verified for the ST-45HRM and ST-70 swing-tube concrete pumps, so you can order with confidence.
- Sustained Pumping Output — A properly functioning unloading valve cartridge maintains consistent concrete delivery pressure; a worn or stuck cartridge leads to erratic output or complete loss of pumping force.
- Hydraulic System Integrity — Correct valve cartridge seating prevents uncontrolled pressure release in the hydraulic circuit, protecting downstream components and operator safety during operation.
The unloading valve cartridge controls the release of hydraulic pressure within the pump's valve circuit, allowing the system to cycle correctly between the pressure and return stages of each pumping stroke. When this cartridge is worn, damaged, or sticking, the pump may lose output pressure, cycle inconsistently, or fail to move concrete altogether. Replacing it with the correct OEM cartridge restores proper hydraulic flow and keeps the ST-series pump delivering concrete at the rate and pressure the job demands.
