Multiquip 3054935 Suction and Discharge Gasket

The Multiquip 3054935 Suction and Discharge Gasket is a genuine OEM replacement designed for D306, MQ-D306HA, and MQ-D305 series diaphragm pumps. Sourced directly from Multiquip, this gasket delivers the correct material grade and sealing profile needed to maintain a leak-free connection at both the suction and discharge ports. Verify your model code against the fitment list to confirm compatibility before ordering. DHS Equipment stocks this part to keep your Multiquip diaphragm pump operating at full capacity.

Key Features

• OEM-Grade Sealing Material — Manufactured to the same material specification as the original, ensuring proper compression and a fluid-tight seal at the suction and discharge interfaces.
• Drop-In Port Compatibility — Engineered to match the exact bolt pattern and port geometry of the D306, MQ-D306HA, and MQ-D305 diaphragm pumps for a direct, hardware-matched installation.
• Confirmed Fitment — Verified for MQ diaphragm pump models D306, MQ-D306HA, and MQ-D305; always cross-reference your model code before ordering.
• Sustained Flow Performance — A properly seated suction and discharge gasket maintains prime, prevents air ingestion, and supports full pump output; a degraded gasket causes pressure loss and erratic flow.
• Fluid System Integrity — Correct gasket sealing at both the suction and discharge ports prevents uncontrolled fluid leakage, an important consideration when pumping hazardous or corrosive media.

The suction and discharge gasket forms a compression seal between the pump body and the suction or discharge manifold, preventing air from entering the fluid path and stopping pumped liquid from escaping at the port joints. On a diaphragm pump, even a minor loss of seal at these points can break prime, reduce flow rate, and cause the pump to cavitate or run dry. When this gasket deteriorates — through chemical exposure, heat cycling, or compression set — replacing it promptly restores full pump efficiency and protects the surrounding components from fluid damage.
