Key Features
- Genuine OEM Construction — Manufactured to Multiquip's exact material and dimensional specifications for the ST30 auto compensation system, ensuring the tube performs as intended within the pumping circuit.
- Direct ST30 Fitment — Engineered specifically for the ST30 swing tube concrete pump; installs into the auto compensation assembly without modification to surrounding components.
- Maintains Pumping Pressure Integrity — A correctly functioning auto comp tube keeps the concrete pumping circuit sealed and pressurized, supporting consistent output stroke performance.
- Prevents Circuit Bypass and Output Loss — A worn or damaged tube can allow hydraulic or material bypass within the compensation system, leading to inconsistent pump output and potential damage to adjacent components.
- Sourced Through Authorized Distribution — Supplied by DHS Equipment as an authorized Multiquip parts distributor, backed by proper part number traceability for the ST30 platform.
The auto comp tube on the ST30 concrete pump is part of the automatic compensation assembly that manages pressure balance within the swing tube pumping system. It helps maintain consistent sealing and flow control as the swing tube cycles between the pump cylinders, which is critical to delivering steady concrete output at the discharge point. When this tube degrades or fails, the compensation system loses its ability to maintain proper circuit pressure, which can result in reduced pump efficiency, erratic output, or accelerated wear on surrounding hydraulic and pumping components.
