The Multiquip EM981121 Return Filter Element is a genuine OEM component designed for LS-series hydraulic concrete pumps, including the LS400, LS500, LS600, LS60TD, LS40D, LS40TD, and LS50TD. As a direct OEM replacement, this element meets the original engineering specifications for the hydraulic return circuit, ensuring consistent filtration performance across every pumping cycle. Sourced directly through Multiquip's authorized parts network, the EM981121 is the correct service part for scheduled hydraulic maintenance on these machines.
Key Features
- Genuine OEM Filtration Media — Manufactured to the original micron rating and flow capacity specified for the LS-series hydraulic return circuit, not a generalized substitute.
- Direct-Fit Replacement — Engineered to seat and seal in the existing filter housing with no rework, matching the original element's dimensions and end-cap configuration.
- Broad LS-Series Compatibility — Confirmed fitment across LS400, LS500, LS600, LS60TD, LS40D, LS40TD, and LS50TD hydraulic concrete pump models.
- Protects Hydraulic System Integrity — A clean return line keeps bypassed contamination out of the reservoir, preventing abrasive wear on pumping cylinders, valves, and seals downstream.
- Hydraulic System Safety — A clogged or failed return filter can cause pressure spikes and uncontrolled fluid bypass in the hydraulic circuit; replacing on schedule with the correct OEM element is a critical safety and reliability practice on concrete pump equipment.
The return filter element sits in the hydraulic return line between the actuating components and the fluid reservoir. Its job is to capture contaminants, metal particles, and debris before they re-enter the tank and circulate back through the pump's hydraulic system. When this element becomes saturated or bypassed, unfiltered fluid degrades valves, seals, and cylinder bores — leading to erratic pump output, increased heat, and accelerated wear throughout the entire hydraulic circuit. Regular replacement with a correctly rated element like the Multiquip EM981121 is one of the most effective ways to extend the service life of an LS-series concrete pump.
