The Wacker Neuson Negative Pressure Flange is a genuine OEM component designed for MDP3 and PT3c series pumps. Sourced directly from Wacker Neuson, this part meets the exact engineering specifications of the original, ensuring a direct drop-in fit with no guesswork. It is confirmed compatible with the MDP3 and PT3c model lines, covering both CE and CN variants. When you need to restore proper pump performance, this is the correct part for the job.
Key Features
- Genuine OEM Sealing Integrity — Manufactured to Wacker Neuson's exact dimensional tolerances, ensuring the flange maintains the negative pressure differential critical to consistent pump operation.
- Direct Drop-In Installation — Matches the original mounting interface and port geometry, so the flange seats and seals correctly without rework or shimming.
- Broad Pump Series Coverage — Fits MDP3 and PT3c series pumps across CE and CN variants, making this a practical stock item for fleets running multiple Wacker Neuson pump configurations.
- Sustained Suction Performance — A correctly seated negative pressure flange maintains the vacuum integrity the pump depends on to prime and move fluid efficiently; a worn or cracked flange leads to air ingestion and loss of prime.
- Verified Part Number — Part number 5100061605 is confirmed against Wacker Neuson OEM documentation for the listed models, giving you confidence before the part ships.
The negative pressure flange is a structural sealing component located at the suction side of the pump assembly. It creates and maintains the low-pressure zone that allows the pump to draw fluid in, and it forms a critical seal between the pump housing and the intake path. If this flange becomes cracked, warped, or improperly seated, air is drawn into the system, the pump loses its prime, and fluid delivery drops off or stops entirely — making prompt replacement essential to keeping the pump operational.
