The Multiquip 2023354 Suction Connection and Groove Pin Assembly is a genuine OEM part designed for MQ Diaphragm Pump series equipment. Sourced directly from Multiquip, this assembly ensures the suction inlet connects and seals exactly as the original design intended, with no guesswork on fitment for MQ diaphragm pump models. Keeping this assembly in proper working condition is essential to maintaining consistent pump performance and suction efficiency on the job.
Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original design specifications, ensuring the connection geometry and groove pin dimensions match the pump's factory assembly exactly.
- Direct-Fit Installation — Designed to drop into place on MQ Diaphragm Pump models, aligning with existing inlet ports and retaining hardware without modification.
- MQ Diaphragm Pump Compatibility — Confirmed fitment for MQ Diaphragm Pump series equipment, so you can order with confidence knowing this is the correct assembly for your machine.
- Maintains Suction Integrity — A correctly seated suction connection and groove pin assembly holds inlet pressure and prevents air ingestion that would rob the pump of prime and flow capacity.
- Complete Assembly — Supplied as a full connection and groove pin assembly, so both the suction connector and retaining pin are replaced together for a thorough, lasting repair.
The suction connection is the entry point where fluid is drawn into the pump body, and the groove pin locks the connection securely in position to prevent movement or separation under operating pressure. Together, they form a critical seal and retention point at the inlet side of the pump — if the connection becomes loose, cracked, or the pin fails, the pump will lose prime, draw in air, and deliver reduced or no flow. Replacing this assembly restores a sound, leak-free suction path and allows the diaphragm pump to maintain the consistent priming and discharge performance it was built to deliver.
