The Multiquip 100KDO7520 Pump Housing ST-4125 is a genuine OEM component designed for the ST-4125 concrete pump. Sourced directly from Multiquip, this pump housing delivers the exact fit and structural integrity required to keep the ST-4125 operating at full capacity. As a genuine OEM part, it meets the original design specifications for the ST-4125 swing tube concrete pump platform, giving you confidence that this is the correct replacement for your machine.
Key Features
- Genuine OEM Construction — Manufactured to the original design tolerances for the ST-4125 pump housing, ensuring proper sealing surfaces and structural integrity under high-pressure pumping conditions.
- Direct-Fit Replacement — Engineered to bolt into the existing pump assembly on the ST-4125 without modification, aligning correctly with all mating components including seals, wear plates, and the swing tube.
- ST-4125 Specific Fitment — Confirmed fitment for the Multiquip ST-4125 concrete pump, so you can order with confidence knowing this housing matches your machine's configuration.
- Structural Integrity Under Load — The pump housing forms the primary pressure-bearing envelope of the concrete pump; a correctly fitted OEM housing maintains consistent output pressure and prevents concrete bypass or leakage at the housing joints.
- Critical Pressure-Containment Component — On a concrete pump, a cracked or compromised housing can result in sudden pressure loss or uncontrolled material discharge; replacing with a genuine OEM housing restores safe, controlled operation.
The pump housing is the main structural body of the concrete pump unit, enclosing the pumping mechanism and containing the hydraulic pressure generated during concrete delivery. It provides the mounting points for wear components such as the swing tube, spectacle plate, and cutting ring, while maintaining a sealed chamber that directs material flow through the outlet. When the pump housing becomes cracked, worn, or damaged, the pump loses the ability to maintain consistent pressure, resulting in reduced output, material leakage, and potential safety hazards on the jobsite. Replacing it with a genuine OEM part restores the correct pressure envelope and ensures all internal components seat and function as originally designed.
