The Wacker Neuson Volute Insert Kit is a genuine OEM component designed for PTS4V and PTK4 series self-priming centrifugal trash pumps. As a direct factory replacement, this kit ensures the internal volute geometry is restored to original specification, maintaining proper fluid dynamics and pump output. It is confirmed compatible with the PTS4V, PTS4V(I), and PTK4 pump models, making it a straightforward service solution for these 4-inch discharge units.
Key Features
- Genuine OEM Integrity — Manufactured to Wacker Neuson's original design tolerances, ensuring the volute insert seats correctly and maintains the pump housing's internal flow path without gaps or misalignment.
- Drop-In Service Replacement — Engineered to fit directly into the existing pump housing, matching all mounting points and sealing surfaces of the original volute insert.
- Broad PTS4V and PTK4 Compatibility — Fits multiple PTS4V configurations as well as the PTK4(I) pump kit variant, covering a wide range of 100mm/4-inch Wacker Neuson trash pump builds.
- Restored Pump Efficiency — A worn or damaged volute insert causes turbulence, pressure loss, and reduced flow rate; replacing it restores the tight clearances needed for consistent, high-volume fluid transfer.
- Complete Kit Format — Supplied as a full kit so all necessary insert components are on hand for a single service event, avoiding partial repairs and repeat strip-downs.
The volute is the spiral-shaped casing inside a centrifugal pump that collects fluid from the impeller and converts its velocity into pressure as it moves toward the discharge outlet. The volute insert sits within this housing and defines the precise clearances around the impeller — tight tolerances here are critical to generating the pump's rated flow and lift. When the insert wears, erodes from abrasive debris, or becomes damaged, those clearances open up, fluid recirculates internally, and the pump loses both prime and output capacity. Replacing the 5000076822 Volute Insert Kit returns the pump's internal geometry to spec and brings discharge performance back in line.
