The Multiquip CD101517 Diaphragm is a genuine OEM component designed for CDM1H series core drill equipment. As a direct OEM replacement, it meets the original design specifications used during factory assembly, ensuring compatibility and correct function within the fluid or air transfer system. This diaphragm is confirmed to fit the CDM1H, making it a straightforward service part for technicians and operators maintaining their core drill units. Sourced from Multiquip's authorized parts supply, the CD101517 gives you confidence that you're installing the right part the first time.
Key Features
- Genuine OEM Material Grade — Manufactured to the original diaphragm compound specification, delivering the correct flex characteristics and chemical resistance required for sustained fluid transfer performance.
- Direct-Fit Installation — Engineered to seat and seal exactly as the factory component did, with matching port dimensions and mounting geometry for the CDM1H assembly.
- CDM1H Core Drill Compatibility — Verified fitment for the Multiquip CDM1H core drill series; always cross-reference your model and part number before ordering.
- Sustained Transfer Efficiency — A correctly functioning diaphragm maintains consistent fluid or air delivery; a cracked or fatigued diaphragm results in pressure loss and erratic operation.
- Fuel System Integrity — Diaphragms in fuel and primer circuits directly affect engine starting and running reliability; using an OEM-spec part preserves that integrity.
A diaphragm is a flexible membrane used in fuel pumps, primer bulbs, or carburetor circuits to create the pressure differential needed to move fuel or air through a system. On equipment like the CDM1H core drill, the diaphragm flexes repeatedly with each engine cycle, making it a wear item that degrades over time from heat, fuel exposure, and mechanical fatigue. When a diaphragm fails, the result is typically hard starting, fuel starvation, or complete loss of prime — replacing it promptly with a correct OEM-spec part restores normal operation.
