Multiquip 16030ZM3004 Pump Spring

The Multiquip 16030ZM3004 Pump Spring is a genuine OEM component designed for the DSGPULW Duo Screed and MTX-series rammers including the MTX50HD, MTX60HD, MTX70HD, MTX70HDR, and MTX80HDR. As a direct OEM replacement sourced through Multiquip's authorized parts network, it meets the same specifications as the spring installed at the factory. DHS Equipment stocks this part to keep your screed and rammer equipment running without extended wait times.

Key Features

• Genuine OEM Tension Spec: — Manufactured to exact load and rate tolerances, ensuring the pump operates within its intended pressure range rather than under- or over-springing.
• Direct Drop-In Replacement: — Engineered to seat and retain exactly as the original, with no re-engineering of the pump assembly required during installation.
• Broad Multiquip Fitment: — Compatible with the DSGPULW Duo Screed and MTX50HD, MTX60HD, MTX70HD, MTX70HDR, and MTX80HDR rammers — one part number covering multiple machines in your fleet.
• Consistent Pump Actuation: — A properly tensioned pump spring maintains the correct stroke and fuel or fluid delivery cycle; a fatigued spring causes inconsistent output and hard starts.
• Corrosion-Resistant Construction: — Built to withstand the vibration-intensive environment of rammer and screed operation without premature fatigue or deformation.

The pump spring plays a critical role in the return stroke of the fuel or fluid pump on your equipment. It maintains consistent tension so the pump can draw and discharge at the correct rate with every cycle. When a pump spring weakens, stretches, or breaks, the pump loses its ability to deliver a reliable stroke — leading to hard starts, uneven engine performance, or complete pump failure. Replacing a worn spring promptly restores proper pump function and protects the surrounding pump components from additional wear.
