The Multiquip EM98005SK Seal Kit ST45 is a genuine OEM Seal Kit ST45 designed for the ST45 concrete pump. As a direct OEM part, EM98005SK is sourced and validated by Multiquip to meet the original engineering specifications of the ST45, ensuring every seal in the kit fits and performs exactly as intended. This kit is the correct service solution when addressing fluid integrity issues on ST45 series concrete pumps.
Key Features
- OEM-Grade Seal Materials — Each seal in this kit is manufactured to the original compound and durometer specification required for ST45 concrete pump hydraulic and fluid circuits, delivering consistent compression and resistance to pressure cycling.
- Complete Kit Configuration — Supplies all required seals for the service interval in a single package, so technicians can complete the rebuild without sourcing individual components separately.
- Confirmed ST45 Fitment — Engineered specifically for the Multiquip ST45 swing-tube concrete pump; verify your model code before installation.
- Prevents Fluid Bypass and Leakage — Worn or hardened seals in a concrete pump allow hydraulic fluid or slurry to bypass, causing pressure loss, contamination, and accelerated wear on pump components — a fresh seal kit restores proper containment and output pressure.
- Critical for Pressure-Side Safety — Concrete pumps operate under significant hydraulic pressure; maintaining seal integrity is essential to safe operation and preventing uncontrolled fluid discharge at the pump head or cylinder.
A seal kit contains the full set of elastomeric and composite seals used throughout a concrete pump's hydraulic cylinders, piston assemblies, and fluid passages. These seals maintain the pressure boundaries that allow the pump to move concrete efficiently through the delivery line. When seals degrade — due to heat cycles, abrasive slurry contact, or age — the pump loses output pressure, develops external leaks, or suffers internal bypass that reduces throughput. Replacing the full kit at the recommended service interval restores hydraulic efficiency and protects the pump's internal components from secondary damage.
