The Wacker Neuson Volute is a genuine OEM Volute designed for the PT2A and PT2A(I) series trash pumps. As a direct OEM replacement, this part is manufactured to the same specifications as the original component that left the factory, ensuring a correct fit within the pump housing without guesswork or modification. If your pump is losing prime, delivering reduced flow, or showing visible damage to the pump casing, replacing the Volute with the correct is the right call. Sourced directly through authorized Wacker Neuson supply channels, this is the same part used in original equipment production.
Key Features
- OEM Casing Integrity — Manufactured to original Wacker Neuson tolerances, ensuring the internal flow geometry of the Volute matches the pump's designed hydraulic path exactly.
- Direct Housing Replacement — Drops into the PT2A and PT2A(I) pump assembly using the original mounting points and sealing surfaces, requiring no reworking of adjacent components.
- Confirmed PT2A and PT2A(I) Fitment — Verified for compatibility across the PT2A and PT2A(I) model series, covering both standard and variant configurations.
- Restores Full Pump Output — A worn or cracked Volute disrupts the fluid velocity conversion that drives discharge pressure; replacing it with part 5100042630 brings flow and head pressure back to spec.
- Genuine OEM Part — Backed by Wacker Neuson's OEM supply chain, giving you confidence that material grade and dimensional accuracy match the original component.
The Volute is the spiral-shaped casing that surrounds the pump impeller and converts the high-velocity fluid generated by the spinning impeller into usable discharge pressure. As water or slurry exits the impeller, the gradually widening chamber of the Volute slows the fluid and increases its pressure, directing it toward the pump outlet. When the Volute cracks, erodes, or becomes damaged — common in trash pump applications handling abrasive materials — the pump loses the ability to build adequate pressure, resulting in poor flow rates and an inability to prime or lift fluid effectively.
