The Wacker Neuson Mechanical Seal is a genuine OEM component designed for MDP3, MDP3X, and PT3G-c series diaphragm and trash pumps. Sourced directly from Wacker Neuson, this seal matches the original part specification so it installs in place of the worn component without guesswork or adaptation. It is confirmed to fit MDP3-CE, MDP3X, MDP3-CN, PT3G-c CE, and PT3G-c CN pump models, making it a versatile service part across the MDP3 and PT3G-c families. When you need to restore pump integrity and keep fluids contained, this is the correct part for the job.
Key Features
- OEM-Grade Sealing Material — Manufactured to Wacker Neuson's original material and compression specifications, ensuring the seal face and elastomer perform as intended in wet pump environments.
- Drop-In Installation — Engineered to seat in the same bore and mounting position as the original, so the seal installs directly without machining or fitting adjustments.
- Broad MDP3 and PT3G-c Fitment — Confirmed for MDP3-CE, MDP3X, MDP3-CN, PT3G-c CE, and PT3G-c CN pump models, covering both the 75mm/3-inch diaphragm and trash pump variants.
- Prevents Fluid Bypass and Leakage — A properly functioning mechanical seal keeps the pumped fluid isolated from the drive shaft, protecting internal components and maintaining pump output pressure.
- Genuine Wacker Neuson OEM Part — Supplied as an authorized Wacker Neuson replacement, verifiable by part number 5100061611, so you can order with confidence that you are receiving the correct factory component.
A mechanical seal creates a dynamic, fluid-tight barrier between the rotating pump shaft and the pump housing, preventing water or fluid from migrating into the drive or engine assembly. It works by pressing two precision-lapped seal faces together — one stationary and one rotating — to contain pressure during pump operation. When the seal wears, becomes scored, or loses its elastomer integrity, fluid begins to leak past the shaft, leading to reduced pump efficiency, wet engine components, and potential bearing damage if left uncorrected.
