The Multiquip EM518993 Heat Exchanger Assembly is a genuine OEM component designed for LS400, LS500, LS600, and LS600P hydraulic-driven concrete pumps. As a factory-sourced replacement, this assembly matches the original equipment specification and installs directly into the hydraulic cooling circuit without modification to surrounding components. Sourced through Multiquip's authorized parts network, the EM518993 ensures your pump's thermal management system is restored to its intended operating condition. Confirm your model code against the fitment list before ordering to ensure a direct application match.
Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original design tolerances, ensuring the correct flow capacity, port sizing, and thermal transfer performance for the LS-series hydraulic system.
- Direct Application Fit — Engineered to replace the original assembly on LS400, LS500, LS600, and LS600P concrete pumps with matching mounting points and hydraulic connections.
- Hydraulic Heat Management — Maintains hydraulic fluid temperature within the operating range required to protect seals, valves, and pump internals during continuous concrete pumping cycles.
- Protects Downstream Components — A functioning heat exchanger prevents thermal breakdown of hydraulic fluid, which can lead to accelerated wear of the hydraulic pump, control valves, and cylinders.
- Verified OEM Part Number — EM518993 is the exact Multiquip part number for this assembly, giving you confidence you are ordering the correct replacement for your LS-series machine.
The heat exchanger assembly in a hydraulic-driven concrete pump is responsible for dissipating heat generated by the hydraulic system during operation. As hydraulic fluid circulates under pressure to drive the pumping cylinders and valves, it accumulates heat that must be removed to prevent fluid degradation and component damage. When the heat exchanger becomes blocked, corroded, or develops a leak, hydraulic fluid temperatures rise unchecked — leading to seal failure, reduced pumping output, and potential shutdown of the machine mid-pour. Replacing a failed unit with the correct OEM assembly restores the thermal regulation the system depends on.
