Impeller | PT3, PT3A (New Style)

The Wacker Neuson Impeller is a genuine OEM component designed for the PT3 series 75mm/3-inch centrifugal trash pumps, including the PT3, PT3A, PT3H, and PT3V models. As a direct OEM replacement, this impeller is sourced and validated by Wacker Neuson to match the original part in geometry, material, and hydraulic performance across the full PT3 pump family. Whether you're servicing a PT3A, PT3H, or PT3V unit, part number ensures a correct, straight-swap installation with no guesswork. Keep your trash pump moving water at rated capacity by replacing a worn or damaged impeller with the correct OEM-spec component.

Key Features

• OEM Hydraulic Geometry: — Engineered to the original vane profile and diameter specifications, maintaining rated flow and head pressure output for 3-inch trash pump operation.
• Direct-Swap Installation: — Matches the original impeller mounting interface on PT3 series pumps, bolting directly onto the pump shaft without modification to the volute or housing.
• Broad PT3 Family Fitment: — Compatible across PT3, PT3A, PT3H, and PT3V pump variants, covering a wide range of machine numbers within the 75mm/3-inch centrifugal trash pump lineup.
• Sustained Flow Performance: — A correctly seated impeller is the core driver of pump output; a worn or eroded impeller causes loss of prime, reduced discharge volume, and overworked engine load.
• Genuine Wacker Neuson OEM Part: — Supplied as an authorized OEM component under part number 5000117806, ensuring material grade and dimensional accuracy consistent with the original production part.

The impeller is the rotating heart of a centrifugal trash pump. Mounted on the pump shaft and housed inside the volute casing, it spins at high speed to draw fluid in through the suction port and accelerate it outward through the discharge outlet using centrifugal force. In trash pump applications, the impeller must handle water carrying solids, debris, and abrasive particles — making material integrity and vane geometry critical to long service life. When an impeller wears, erodes, or becomes damaged, the pump loses its ability to maintain prime, discharge volume drops noticeably, and the engine may labor under increased load as efficiency falls. Replacing a worn impeller promptly restores full pump capacity and protects the surrounding volute and seal assembly from secondary damage.
