The Multiquip EM16512 Return Filter Assembly is a genuine OEM component designed for ST-45HRM and ST-70 series concrete pumps. As an OEM part sourced directly through Multiquip, EM16512 is manufactured to the same specifications as the original, ensuring a direct, correct-fit installation with no guesswork. DHS Equipment supplies this part to contractors and service technicians who need verified fitment and dependable hydraulic system performance on their concrete pump equipment.
Key Features
- Genuine OEM Construction: — Manufactured to original Multiquip specifications, meaning the filter media grade, housing dimensions, and flow capacity match exactly what left the factory in your ST-series pump.
- Direct-Fit Replacement: — Engineered to install into the hydraulic return line circuit of compatible ST-series machines, connecting to existing ports and mounting points without alteration.
- Confirmed Fitment: — Verified compatible with Multiquip ST-45HRM and ST-70 concrete pump models.
- Hydraulic System Protection: — A properly functioning return filter keeps particulate contamination out of the hydraulic reservoir, protecting pumps, valves, and cylinders from accelerated wear caused by circulating debris.
- Prevents Costly Hydraulic Damage: — A clogged or failed return filter allows bypass of contaminated fluid back into the system, which can lead to control valve erosion, cylinder scoring, and full hydraulic circuit failure if left unaddressed.
The return filter assembly sits in the hydraulic return line of the concrete pump, capturing contaminants as fluid cycles back to the reservoir after driving the pump's hydraulic components. It plays a critical role in maintaining clean hydraulic fluid, which directly affects the responsiveness and service life of every downstream hydraulic component in the machine. When the filter becomes blocked or compromised, contaminated oil re-enters the system, accelerating wear on seals, valves, and the hydraulic pump itself — making timely replacement essential to uninterrupted pump operation.
