The Multiquip EM98275 Return Oil Element is a genuine OEM hydraulic filtration component designed for LS400, LS500, LS600, and LS600P concrete pumps with serial number 281101 and above. As a factory-sourced part, the EM98275 meets the exact specifications required to maintain proper hydraulic system performance across the LS-series pump lineup. Sourced directly through Multiquip's OEM supply chain, this element ensures the correct media grade, flow rating, and dimensional fit for a direct drop-in installation. DHS Equipment stocks this part to keep your Mayco concrete pump operating at peak hydraulic efficiency.
Key Features
- Genuine OEM Filtration Media — Factory-specified filter media grade ensures consistent particle capture efficiency for the LS-series hydraulic return circuit, protecting sensitive pump components from contamination.
- Serial Number-Specific Fitment — Engineered for LS400, LS500, LS600, and LS600P units with serial number 281101 and above, confirming compatibility with the correct filter housing and port dimensions on these production builds.
- Direct Housing Replacement — Installs directly into the existing return oil filter housing with no adaptation, maintaining correct bypass valve engagement and sealing integrity.
- Protects Hydraulic System Integrity — A fresh return oil element keeps metal particles, wear debris, and contamination out of the hydraulic circuit, preventing premature valve and cylinder wear that leads to costly pump repairs.
- Scheduled Maintenance Compliance — Replacing this element at manufacturer-recommended service intervals is critical for sustaining hydraulic pressure consistency and extending pump service life on demanding concrete placement jobs.
The return oil element filters hydraulic fluid as it cycles back from the pump's actuators and cylinders into the reservoir. By capturing wear particles and contaminants before they re-enter the system, this element prevents abrasive buildup in control valves, cylinders, and seals. When the element becomes clogged or degraded, back pressure can rise, bypass valves may open unintentionally, and unfiltered fluid can circulate through the hydraulic circuit — accelerating wear on every downstream component and compromising the pump's output consistency.
