The Multiquip EM98049 Heat Exchanger is a genuine OEM component designed for the ST-45HRM concrete pump. As a direct Multiquip OEM part, it is manufactured to the exact specifications of the original unit, ensuring a correct fit and consistent thermal performance. This part is sourced directly through authorized Multiquip supply channels and sold by DHS Equipment, giving you confidence in what you are installing.
Key Features
- OEM Thermal Specification: — Engineered to match the original heat transfer capacity of the ST-45HRM, maintaining the hydraulic and fluid system temperatures the pump was designed to operate within.
- Direct Drop-In Replacement: — Matches the original mounting configuration and connection points of the ST-45HRM, allowing straightforward installation without adaptation.
- Confirmed Fitment: — Verified for use on the Multiquip ST-45HRM concrete pump with hopper remixer.
- Prevents Overheating Damage: — A properly functioning heat exchanger keeps hydraulic fluid temperatures in check, protecting internal pump components from heat-related wear and premature failure.
- Critical Hydraulic System Protection: — Thermal runaway in a hydraulic concrete pump can cause seal degradation and fluid breakdown; replacing a worn exchanger restores the system's ability to dissipate heat safely during continuous operation.
A heat exchanger in a hydraulic concrete pump is responsible for cooling the hydraulic fluid as it circulates through the system. During sustained pumping cycles, hydraulic fluid generates significant heat, and without effective cooling, fluid viscosity breaks down and internal components — including seals, valves, and the pump drive — are exposed to damaging temperatures. When the heat exchanger becomes blocked, corroded, or fails, the machine will overheat, leading to fluid degradation, potential seal failure, and unplanned shutdowns. Replacing it with a genuine OEM unit like the Multiquip EM98049 restores proper thermal regulation and protects the full hydraulic circuit.
