The Multiquip 49290 Mechanical Pump Clutch is a genuine OEM component designed for the WSC55 Chemical Spray System. Sourced directly from Multiquip, part 49290 ensures an exact match to the original specification — no guesswork on fitment or compatibility. As a genuine OEM part, it is manufactured to the same standards as the original component installed at the factory, giving you confidence that it will perform correctly in your WSC55 unit. DHS Equipment stocks this part to keep your spray system operational and ready for work.
Key Features
- Genuine OEM Construction — Built to the same mechanical tolerances as the original clutch, ensuring correct engagement force and consistent pump actuation in the WSC55.
- Direct-Swap Replacement — Matches the original mounting configuration of the WSC55 pump drive assembly, allowing straightforward installation without modification.
- Confirmed WSC55 Fitment — Validated for use on the Multiquip WSC55 Chemical Spray System; verify your model before ordering.
- Sustained Pump Output — A properly functioning mechanical clutch maintains full engagement between the drive and pump, preserving consistent spray pressure and flow rate throughout operation.
- Wear Resistance — OEM-grade materials resist the friction and heat generated during repeated clutch engagement cycles, extending service life between replacements.
The mechanical pump clutch connects and disconnects drive power to the spray pump, giving the operator control over pump engagement without stopping the engine. When the clutch is functioning correctly, it transfers rotational force smoothly and fully to the pump, maintaining steady output pressure. A worn or failing clutch can result in slipping engagement, reduced spray volume, or complete loss of pump drive — making timely replacement essential to keeping the system performing as intended.
