The Wacker Neuson is a genuine OEM Output Flange Gasket designed for MDP3 and PT3c series diaphragm and trash pumps. As a factory-authorized Wacker Neuson part, is produced to the exact material and dimensional standards required for a proper seal at the pump's output flange connection. This gasket is confirmed to fit the MDP3, MDP3X, MDP3-CN, PT3G-c CE, and PT3G-c CN pump models, covering both CE and CN variants across the lineup. Keeping the correct OEM gasket in place is a straightforward way to maintain pump integrity and avoid fluid bypass at the discharge point.
Key Features
- OEM Sealing Material Grade — Manufactured by Wacker Neuson to the exact compression and material specification required at the output flange, ensuring a consistent, leak-free seal under pump operating pressures.
- Direct-Fit Flange Replacement — Matches the original gasket profile and bolt-pattern footprint, so it seats correctly between the output flange faces without trimming or reworking mating surfaces.
- Broad MDP3 and PT3c Series Coverage — A single part number covers MDP3, MDP3X, MDP3-CN, PT3G-c CE, and PT3G-c CN models, making it the correct choice across both the 75mm/3-inch diaphragm trash pump and water pump variants.
- Protects Pump Output Flow — A healthy output flange gasket keeps pressurized flow directed through the discharge port; a cracked or compressed-out gasket allows bypass leakage that reduces output performance and can escalate to seal damage on surrounding components.
- Fluid-System Integrity — On pumps handling debris-laden or contaminated water, a correctly sealed output flange prevents backflow contamination at the discharge joint, supporting safe and compliant operation on sensitive job sites.
The output flange gasket forms the static seal between the pump body's discharge port and the output flange fitting, preventing water or slurry from escaping the pressurized flow path at that joint. When the gasket degrades — through compression set, chemical exposure, or physical damage — the seal breaks down and flow leaks externally rather than being directed through the discharge hose, reducing pump efficiency and potentially damaging connected components. Replacing this gasket with the correct OEM part restores the integrity of the discharge connection and returns the pump to full working condition.
