The Wacker Neuson Volute Insert is a genuine OEM component designed for the PT6LT, PT6LS, PT6Y, PT6YT, and PTK6 series 6-inch centrifugal trash pumps. As a direct OEM replacement, this part is manufactured to the same specifications as the original, ensuring a correct, trouble-free installation with no guesswork on fit or function. It is compatible across a wide range of PT6 configurations including trailer-mounted, skid-mounted, and EPA T4-compliant variants. Keep your high-volume pump performing at full capacity with this verified replacement part sourced straight from Wacker Neuson.
Key Features
- Genuine OEM Casting Integrity — Manufactured to the original material and dimensional spec, ensuring the volute chamber maintains the hydraulic profile needed for full pump efficiency.
- Drop-In Housing Fit — Engineered to seat directly into the pump casing of PT6 series units with no machining or adjustment required during installation.
- Broad PT6 Series Coverage — Fits PT6LT, PT6LS, PT6Y, PT6YT, PTK6, and their EPA T4 and international variants, including trailer-mounted and skid-mounted configurations.
- Sustained Flow Performance — A correctly fitted volute insert preserves the pump's discharge pressure and volume output; a worn or damaged insert causes cavitation, flow loss, and accelerated impeller wear.
- Verified OEM Part Number — Part number 5000072349 is the current Wacker Neuson OEM reference for this insert across all listed PT6 models, so you can order with confidence.
The volute insert is the shaped inner liner seated inside the pump's casing that forms the curved flow passage surrounding the impeller. Its geometry converts the high-velocity fluid thrown outward by the spinning impeller into pressure, directing the water or slurry efficiently toward the discharge port. When the volute insert becomes worn, cracked, or eroded — common in trash pump applications handling abrasive debris — the hydraulic seal between the insert and impeller degrades, causing the pump to lose prime, drop discharge pressure, and work harder to move the same volume of fluid. Replacing it with a correctly dimensioned OEM insert restores the pump's rated performance and protects the impeller from further damage.
