Multiquip EM518993 Heat Exchanger LS - OEM Replacement Part

The heat exchanger is a critical cooling system component that regulates hydraulic oil temperature in Multiquip LS-series concrete pumps, preventing overheating during high-demand pumping operations. By dissipating heat generated by the hydraulic system—which operates at pressures up to 4400 PSI in the main circuit and 1750 PSI in auxiliary circuits—this heat exchanger maintains optimal oil viscosity and system performance. Excessive hydraulic oil temperatures can cause seal failure, reduced pump efficiency, and potential system shutdown, making the heat exchanger essential for reliable operation in concrete placement applications.

This OEM heat exchanger is engineered specifically for the LS-series pump design, ensuring proper fitment and thermal management capacity for the demanding hydraulic circuits that power the concrete cylinders, shuttle tube mechanism, and optional agitator systems. Regular inspection of the heat exchanger for debris buildup, fin damage, or leaks is critical to maintaining cooling efficiency.

Compatible with the following Multiquip concrete pump models:

• LS400/LS500
• LS450
• LS600
• LS600P
