The Multiquip 34490 Wave Washer is a genuine OEM Wave Washer designed for MQ600 series trash pumps, including the MQ600TD80-TLRB, MQ600TD80-TLRP, MQ600H, MQ600HTB, and MQ600HTP. As a direct OEM replacement, this wave washer meets the exact specifications set by Multiquip, ensuring it seats and functions correctly within the pump assembly. Sourced through DHS Equipment's authorized Multiquip parts supply, part number 34490 is the correct service component for these machines.
Key Features
- Genuine OEM Spring Tension Accuracy — Manufactured to Multiquip's exact load and deflection specification, maintaining the correct clamping force this washer is engineered to deliver in the pump assembly.
- Drop-In Installation — Matches the original mounting profile and diameter, seating directly into the same position as the factory-installed component without modification.
- Confirmed Fitment for MQ600 Trash Pumps — Verified for MQ600TD80-TLRB, MQ600TD80-TLRP, MQ600H, MQ600HTB, and MQ600HTP models.
- Sustained Clamping Integrity — A properly functioning wave washer maintains consistent axial preload on fastened components; a worn or flattened washer can allow loosening under vibration, leading to leaks or mechanical failure in a high-cycle pump environment.
- Authorized Multiquip Replacement — Supplied as a genuine OEM part, carrying the same part number 34490 used in Multiquip's own service documentation.
A wave washer is a thin, corrugated spring washer used to apply controlled axial load between fastened components. In a trash pump assembly, it absorbs vibration and maintains preload tension on bolted connections, preventing fasteners from backing off during operation. When a wave washer loses its spring tension — through fatigue, corrosion, or over-compression — it can no longer hold the assembly properly, which may result in loosened hardware, misalignment, or fluid leaks over time.
