The Wacker Neuson Flange is a genuine OEM component designed for the PDT2, PDT2A, PDT2B, PDI2, and PDI2A series 50mm/2-inch diaphragm trash pumps. Sourced directly from Wacker Neuson, this flange is built to the same specification as the original part fitted at the factory. It is a direct-fit replacement across multiple pump configurations in the PDT2 and PDI2 families, covering both standard and inline diaphragm models. If your pump is showing signs of leakage, connection failure, or port wear, replacing the Flange restores a proper, sealed interface at the pump connection point.
Key Features
- Genuine OEM Construction: — Manufactured to Wacker Neuson's exact dimensional and material tolerances, ensuring a flush, leak-free seating surface at the pump port.
- Drop-In Replacement: — Matches the original bolt pattern and port geometry of the PDT2 and PDI2 pump families, so installation aligns without rework or modification.
- Broad PDT2 and PDI2 Fitment: — Verified compatible with PDT2, PDT2A, PDT2B, PDI2, and PDI2A 50mm/2-inch diaphragm trash pumps across multiple serial configurations.
- Maintains Pump Flow Integrity: — A sound flange keeps suction and discharge connections sealed and properly aligned; a cracked or warped flange causes pressure loss and can allow air ingestion that disrupts pump prime.
- Backed by OEM Part Numbering: — Ordering by part number 5000074401 confirms you are receiving the correct flange for your specific pump model, eliminating guesswork at the parts counter.
The flange on a diaphragm trash pump serves as the structural connection point between the pump body and its suction or discharge piping. It provides a flat, machined mating surface that, when bolted and sealed, maintains the pressure differential the pump relies on to move water and debris efficiently. When a flange becomes cracked, eroded, or warped — common results of abrasive slurry passing through the pump — the connection can no longer hold a proper seal, leading to air leaks on the suction side, flow loss, or outright connection failure. Replacing a damaged flange with the correct OEM part restores the pump's ability to maintain prime and deliver consistent flow on the job.
