The Wacker Neuson 5200021607 Cap is a genuine OEM component designed for APT4T and APT4S series submersible pumps. This includes Cold Weather, Surge Brake, and Electric Brake variants across both the APT4T and APT4S Pump with Skid configurations. As a direct OEM replacement, the 5200021607 is manufactured to the same specifications as the original part, ensuring a correct, trouble-free installation without guesswork. Keeping this cap in good condition is essential for maintaining the integrity of the pump system across all covered configurations.
Key Features
- Genuine OEM Construction — Manufactured by Wacker Neuson to original production tolerances, ensuring the cap seats and seals exactly as intended on APT4T and APT4S pump assemblies.
- Direct-Fit Replacement — Designed to drop into the same position as the original, with no trimming, adapting, or rework needed during installation.
- Broad APT Series Coverage — Fits multiple APT4T and APT4S variants, including Cold Weather, Surge Brake, Electric Brake, and Pump with Skid configurations.
- Maintains Pump System Integrity — A properly fitted cap keeps internal pump components protected from contamination and moisture ingress, which can lead to premature wear or pump failure if left unchecked.
- Verified Part Number — Part number 5200021607 is confirmed against Wacker Neuson OEM documentation for all listed APT4T and APT4S models, giving you confidence in your order before it ships.
The cap on an APT series submersible pump serves as a protective closure over an access point or port within the pump assembly, shielding internal components from water, debris, and environmental exposure during operation and storage. When this cap is cracked, missing, or improperly seated, it can allow contaminants to enter the pump housing, leading to accelerated wear on internal parts and potential pump failure. Replacing a damaged or worn cap promptly with the correct OEM part helps keep the pump operating as designed across its full service life.
