Multiquip EM98256 Pump Piston LS50TD - OEM Replacement Part

The pump piston is the primary concrete displacement component in structural concrete pumps, responsible for creating the pressure needed to move concrete through delivery lines. This genuine OEM piston assembly is engineered specifically for Mayco LS-series trailer-mounted concrete pumps and is critical for maintaining consistent pumping performance, especially when handling stiff mixes or pumping over long distances.

As detailed in Multiquip operating manuals, the LS-40D/LS-40TD/LS-50TD structural concrete pumps are designed to handle a wide variety of concrete mixes, but maintaining proper piston seal integrity is essential to prevent cavitation and maintain valve efficiency. Worn or damaged pistons can lead to reduced pumping volume, separation issues, and jamming—particularly problematic when pumping long distances or working with admixtures and faster-setting concrete.

This piston assembly is compatible with the following Multiquip Mayco concrete pump models:

• LS-40/LS-40D
• LS-40TD
• LS-50TD
• LS400
• LS450
• LS500
