The Wacker Neuson 119777 Impeller is a genuine OEM component designed for the PT2 series 50mm/2-inch self-priming centrifugal trash pumps, including the PT2, PT2A, PT2H, and PT2V models. As a direct OEM replacement, part 119777 is manufactured to the same specifications as the original, ensuring proper hydraulic clearances and full pumping efficiency from the first installation. This impeller fits across the PT2 family, making it the correct choice whether you're servicing a PT2A, PT2H, or PT2V unit. Keep your pump performing at full capacity with a part engineered specifically for these machines.
Key Features
- Genuine OEM Hydraulic Integrity — Manufactured to original tolerances, maintaining the precise vane geometry needed for full flow and lift performance in 2-inch trash pump applications.
- Direct-Fit Replacement — Engineered to mount directly onto the pump shaft and match the volute housing of PT2 series units, with no reworking of the pump casing required.
- Broad PT2 Family Coverage — Compatible with the PT2, PT2A, PT2H, and PT2V model lines, consolidating your parts inventory for the full range of Wacker Neuson 50mm/2-inch centrifugal trash pumps.
- Restored Pumping Capacity — A worn or damaged impeller causes loss of prime, reduced flow rate, and weak discharge head; replacing with 119777 restores the pump's rated output and suction performance.
- Fuel and Fluid System Safety — Correct impeller fit prevents internal bypass and cavitation that can overheat the pump casing or damage the mechanical seal, protecting the wider pump assembly.
The impeller is the rotating core of a centrifugal trash pump — it spins at high speed to generate the centrifugal force that draws liquid in through the suction port and pushes it out under pressure through the discharge. In a trash pump like the PT2 series, the impeller must also handle semi-solid debris without clogging, so its geometry and material integrity are critical to sustained performance. When an impeller wears down, chips, or becomes out of balance, the pump loses prime easily, flow rate drops noticeably, and the mechanical seal is placed under additional stress — eventually leading to a full pump failure if left unaddressed.
