The Wacker Neuson Volute is a genuine OEM component designed for the APT6S and APT6T series submersible trash pumps, including standard and Cold Weather configurations. As a direct OEM replacement, this volute is manufactured to the same specifications as the original part, ensuring a proper fit within the pump housing without guesswork or modification. It is compatible across multiple APT6 variants — covering surge brake, electric brake, and skid-mount models — making it a straightforward solution for restoring pump performance. Keep part number on hand for planned maintenance or unscheduled repairs to minimize pump downtime.
Key Features
- Genuine OEM Hydraulic Geometry: — Manufactured by Wacker Neuson with the correct internal flow profile, ensuring the volute channels fluid at the designed efficiency for APT6 series pumps.
- Drop-In Housing Replacement: — Engineered to seat directly into the APT6S and APT6T pump casing with correct bolt pattern and sealing surfaces, streamlining the repair process.
- Broad APT6 Series Coverage: — Fits APT6S Pump with Skid, APT6T Pump with Surge Brake, APT6T Pump with Electric Brake, and Cold Weather variants of each — one part number across the full lineup.
- Restored Pump Output: — A damaged or worn volute causes loss of discharge pressure and flow rate; replacing it with this OEM part restores the pump's rated performance and protects the impeller from uneven wear.
- Verified OEM Part Number: — Listed under Wacker Neuson part number 5200021732, cross-referenced directly to the APT6S and APT6T parts diagrams for accurate ordering confidence.
The volute is the shaped housing that surrounds the impeller inside a centrifugal pump. As the impeller spins, the volute's gradually widening chamber converts the high-velocity fluid into pressure, directing flow toward the discharge outlet. A cracked, eroded, or worn volute disrupts this conversion, leading to reduced discharge pressure, increased cavitation risk, and accelerated wear on surrounding pump components. Replacing a damaged volute promptly is essential to keeping the pump operating at its rated capacity.
