The Wacker Neuson Limiter Cap is a genuine OEM component designed for PT3 series 75mm/3-inch centrifugal trash pumps.

Verify your model number before ordering to confirm compatibility with your specific unit.
Key Features
- Genuine OEM Construction: — Manufactured to the original material and dimensional specifications for the Limiter Cap, ensuring the cap seats and retains correctly within the pump assembly.
- Direct Replacement: — Designed to install in place of the original cap without modification, using the same mounting interface as the factory-installed component.
- PT3 Series Fitment: — Compatible with PT3 series 75mm/3-inch centrifugal trash pumps, including multiple PT3 build configurations.
- Preserves Adjustment Range: — A correctly functioning Limiter Cap keeps operator-accessible settings within their intended range, preventing over-adjustment that can affect pump performance or engine operation.
- Fuel System Safety Relevance: — On fuel-related limiter applications, maintaining the cap in good condition is important for keeping adjustments within safe and compliant operating limits.
A Limiter Cap is a small but important restriction device fitted over an adjustment screw — typically on a carburetor or fuel system component — to cap the range of motion available to the operator. Its role is to prevent settings from being moved beyond the manufacturer's intended limits, which helps maintain consistent engine performance and keeps the equipment operating within its designed parameters. When the cap is missing, cracked, or damaged, adjustments can drift out of range, leading to rough running, fuel mixture issues, or non-compliance with emissions or operational standards.
