The Wacker Neuson 5200021719 Impeller is a genuine OEM component designed for APT4T and APT4S series submersible pumps. This includes Electric Brake, Surge Brake, standard, and Cold Weather configurations across both series. As a factory-sourced part, the 5200021719 is manufactured to the same specifications as the original, ensuring consistent hydraulic performance and correct dimensional fit within the pump housing. Whether you're servicing an APT4S pump with skid or an APT4T Cold Weather model, this is the correct OEM replacement to restore your pump to full working order.
Key Features
- OEM Hydraulic Geometry: — Manufactured to original vane and bore specifications, maintaining rated flow output and head pressure across APT4T and APT4S pump configurations.
- Drop-In Housing Fit: — Dimensionally identical to the factory impeller, seating correctly within the pump volute without modification to the shaft, housing, or wear plate.
- Broad APT Series Coverage: — Fits APT4T (Electric Brake and Surge Brake) and APT4S (standard w/Skid) models, including all corresponding Cold Weather variants.
- Restored Flow Performance: — A worn or damaged impeller causes loss of discharge pressure and reduced flow rate; replacing with a genuine OEM part brings the pump back to its rated pumping capacity.
- Genuine Wacker Neuson OEM Quality: — Sourced directly from Wacker Neuson, this part meets the exact material and manufacturing standards of the original component installed at the factory.
The impeller is the rotating core of a centrifugal pump — it spins at high speed to impart velocity to the water or fluid being pumped, converting that motion into flow and pressure through the volute housing. In submersible pump applications like the APT4T and APT4S, the impeller works continuously in direct contact with the pumped medium, making it one of the highest-wear components in the system. When an impeller becomes eroded, cracked, or clogged, the pump loses suction and discharge efficiency, often presenting as reduced output volume or complete loss of prime. Replacing the impeller with a correct OEM part restores the pump's hydraulic balance and ensures the motor is not overloaded compensating for the efficiency loss.
