The Wacker Neuson Temperature Sender is a genuine OEM component designed for the APT6S, APT6T, APT8S, and APT8T pump series, including standard, surge brake, electric brake, and cold weather configurations. As a direct OEM replacement, this part is built to the same specification as the original, ensuring the machine's temperature monitoring system reads accurately and reliably. It fits across the full range of APT6 and APT8 platform variants, making it a straightforward swap for technicians servicing any model in these families. Verify your model number against the fitment list before ordering to confirm compatibility.
Key Features
- OEM-Calibrated Signal Output — Manufactured to the exact electrical resistance and thermal response specification of the original sender, so the pump's temperature gauge or control system receives an accurate reading across the full operating range.
- Direct Plug-In Replacement — Matches the original connector, thread pitch, and mounting configuration, allowing a clean installation without adapters or modifications to existing wiring or ports.
- Broad APT Series Coverage — A single part number covers APT6S, APT6T, APT8S, and APT8T variants, including surge brake, electric brake, and cold weather models, spanning both skid-mount and trailer-mount configurations.
- Protects Against Overheating Damage — An accurate temperature sender keeps the operator informed of fluid temperature in real time; a failed or drifting sender can mask dangerous overheating conditions and lead to costly pump damage.
- Genuine Wacker Neuson OEM Part — Sourced directly from Wacker Neuson, part number 5200021777 carries the same quality assurance as the component installed at the factory.
A temperature sender monitors fluid or engine temperature within the pump system and converts that reading into an electrical signal sent to the gauge or control module. This signal tells the operator whether the machine is running within a safe thermal range. When a temperature sender fails or becomes inaccurate, the gauge may read low or not at all, leaving overheating conditions undetected and putting the pump at risk of heat-related damage. Replacing a faulty sender restores the visibility operators depend on to run the machine safely and confidently.
