Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original design specifications, ensuring the waterbox housing and groove pin interface match the tolerances required for leak-free diaphragm pump operation.
- Complete Assembly — Supplied as a matched waterbox and groove pin unit, eliminating the need to source components separately and simplifying the replacement process.
- Confirmed Fitment for MQ Diaphragm Pumps — Engineered specifically for MQ Diaphragm Pump models, so part number 2023351 installs correctly without modification to surrounding pump components.
- Restores Pump Integrity — A worn or damaged waterbox allows fluid intrusion into areas of the pump not designed to handle it, leading to accelerated diaphragm failure and loss of prime. This assembly restores the correct fluid boundary within the pump.
- Fluid-Seal Critical Component — In diaphragm pump applications, the waterbox plays a direct role in separating fluid chambers and protecting internal drive components — making correct replacement essential to safe and effective pump operation.
The waterbox in a diaphragm pump serves as the fluid-side housing that channels the pumped medium through the pump body while keeping it separated from the mechanical drive components. The groove pin secures key internal elements in proper alignment, preventing movement that would disrupt the diaphragm's stroke and reduce pumping efficiency. When either component is cracked, corroded, or missing, the pump loses its ability to maintain chamber separation, resulting in fluid bypass, loss of output pressure, and potential damage to the drive mechanism.
