The Multiquip 171700200 is a genuine OEM Dowel Pin 1/4" x 1" designed for MQD2HA, MQD3HA, MQD2H, and MQD3H diaphragm pumps. As a factory-sourced component, this pin is manufactured to the exact dimensional tolerances required for proper alignment and secure assembly within the pump. Sourcing the correct OEM dowel pin ensures the mating components seat precisely as intended, maintaining the structural integrity of the pump assembly. Confirm your model code against the fitment list before ordering to ensure a correct match.
Key Features
- Exact OEM Dimensional Tolerancing — Manufactured to the precise 1/4" x 1" specification required for correct component alignment in Multiquip diaphragm pump assemblies.
- Drop-In Assembly Fit — Engineered to seat directly into existing bores without reworking or resizing the receiving holes in the pump housing.
- Compatible with MQD Series Diaphragm Pumps — Verified fitment for MQD2H, MQD2HA, MQD3H, and MQD3HA pump models.
- Maintains Pump Alignment Under Load — A properly installed dowel pin keeps mating components correctly positioned during operation, preventing lateral movement that leads to accelerated wear or leaks.
- Genuine Multiquip OEM Part — Sourced directly from Multiquip, ensuring the material grade and dimensional accuracy match what was originally built into the pump.
A dowel pin is a precision fastening component used to align and locate two or more mating parts within an assembly. In a diaphragm pump, dowel pins keep housings, plates, and covers in exact registration so that internal fluid passages, seals, and moving components remain correctly positioned during operation. When a dowel pin is worn, sheared, or missing, the mating surfaces can shift out of alignment, causing uneven loading on seals, accelerated wear on adjacent components, and potential fluid leakage from the pump body.
