Confirmed fitment for ST30 series equipment makes this the dependable choice when restoring your concrete pump to proper working condition.
Key Features
- Genuine OEM Construction — Manufactured to the precise material and dimensional tolerances required for hydraulic loop integrity in the ST30 pump system.
- Direct ST30 Application — Engineered specifically for the ST30 swing-tube concrete pump, ensuring correct routing and connection within the lost motion hydraulic circuit.
- ST30 Series Fitment — Confirmed compatibility with ST30 concrete pump models; use part number EM27416 to verify fit before ordering.
- Cycle Timing Integrity — A correctly functioning lost motion loop maintains precise hydraulic sequencing between the swing tube and pumping cylinders, keeping output consistent and pressure balanced.
- OEM-Matched Durability — Built to withstand the high-pressure, high-cycle demands of continuous concrete pumping operations without premature wear or failure.
The lost motion loop is a hydraulic circuit component within swing-tube concrete pumps that controls the timing and sequencing of the swing tube as it alternates between the two pumping cylinders. It acts as a pressure buffer, allowing the swing tube to complete its arc at the correct moment in the pumping cycle so concrete flows smoothly and consistently through the outlet. When this loop becomes worn, cracked, or fails, the pump can experience erratic swing timing, pressure surges, or a loss of output — all of which interrupt concrete placement and can place added stress on surrounding hydraulic components.
