Description
The Micro Matic MM-3362-2 is a precision-engineered drive key (or coupling) designed specifically for Procon rotary vane pump assemblies. This critical component acts as the mechanical bridge between the electric motor and the pump, transferring torque to facilitate the circulation of glycol or water in draft beer power packs and carbonation systems. Manufactured from high-specification, glass-filled nylon, the MM-3362-2 is built to handle high-torque start-ups and continuous operation. Because it is designed as a sacrificial wear item, it protects the more expensive motor and pump shafts by shearing in the event of a mechanical jam, preventing a total system failure.
- Model Number: MM-3362-2
- Compatibility: Fits Procon Series 1 through 5 pumps and 5/8″ Y48 carbonator-style motors
- Application: Essential for Micro Matic Pro-Line Remote Power Packs (Models PP4301, PP4302, PP4303, MMPP4301, etc.)
- Material: Premium high-strength glass-filled Nylon for durability and heat resistance
- Function: Connects the motor shaft to the pump’s internal rotary vane mechanism
- Maintenance: A common replacement part for glycol chillers that are cooling but not circulating liquid
- Dimensions: Cylindrical-double flat coupling design for secure mechanical engagement
- Reliability: Engineered for extreme service shifts in stadiums, arenas, and high-volume commercial bars
Technician’s Note: If your glycol chiller displays cold temperatures but your beer lines are warm and foamy, the MM-3362-2 is the most likely culprit. Over time, these keys can round off or shear due to the constant stress of 24/7 circulation. Pro Tip: Always keep a spare MM-3362-2 in your maintenance kit. Replacing this $20 part can restore your entire draft system’s cooling in minutes, saving you from a costly service call or keg waste during a busy shift.
