The Multiquip 336030000 2-Inch Diaphragm is a genuine OEM replacement designed for MQD2H and MQD3H diaphragm pumps. As an authorized Multiquip parts source, DHS Equipment supplies this component direct — so you get the exact part engineered for your machine, not a guess. The 336030000 is the correct diaphragm for these pump models, ensuring a proper seal and full fluid displacement with every stroke.
Key Features
- Genuine OEM Diaphragm Material: — Manufactured to Multiquip's original material and thickness specification, delivering the flex life and chemical resistance required in demanding pump service.
- Drop-In Replacement: — Matches the original mounting bolt pattern and seat geometry of the MQD2H and MQD3H pump housings for a straightforward swap during scheduled maintenance or emergency repair.
- Confirmed Fitment: — Verified for MQD2H and MQD3H Multiquip diaphragm pumps; part number 336030000 cross-references directly to these models.
- Restored Pumping Efficiency: — A worn or cracked diaphragm causes loss of prime, reduced flow, and fluid bypass. Replacing it with this OEM part restores full volumetric output and self-priming capability.
- Fluid Containment Integrity: — In diaphragm pump applications, a compromised diaphragm can allow pumped fluid to enter the air chamber, contaminating the pump and creating a potential hazard. This OEM diaphragm maintains the critical barrier between fluid and air sides of the pump.
The diaphragm is the core pumping element in a diaphragm-style pump. It flexes back and forth — driven by compressed air — to draw fluid in through the inlet valve and push it out through the discharge valve on each stroke. Because the diaphragm is in constant contact with the pumped material, it is a wear item that degrades over time, especially when handling abrasive slurries, chemicals, or debris-laden water. A failed diaphragm results in loss of prime, reduced output, or complete pump failure, making timely replacement essential to keeping operations on schedule.
