The Wacker Neuson 5200021609 is a genuine OEM Band Clamp designed for the APT4S and APT4T series submersible pumps. As a direct factory replacement, this clamp is built to the same specifications as the original, ensuring a secure and stable connection where it counts. It is confirmed to fit multiple APT4S and APT4T configurations, including cold weather, surge brake, and electric brake variants. Keep a spare on hand — this is the kind of small component that can halt pump operation when it fails.
Key Features
- Genuine OEM Construction — Manufactured to Wacker Neuson's original clamping load and material specs, so the clamp delivers consistent holding force without creep or loosening over time.
- Drop-In Replacement — Matches the original Band Clamp profile and fastener interface exactly, allowing straightforward installation without rework or modification.
- Broad APT4 Series Coverage — Fits APT4S Pump with Skid, APT4S Cold Weather, APT4T Surge Brake, APT4T Surge Brake Cold Weather, APT4T Electric Brake, and APT4T Electric Brake Cold Weather variants.
- Secure Pump Assembly Integrity — A properly functioning band clamp keeps critical pump housing joints sealed and aligned; a failed or over-stretched clamp can allow misalignment that leads to leaks or component separation.
- Part Number Confidence — Order by Wacker Neuson part number 5200021609 to ensure you receive the correct clamp for your specific APT4 pump configuration.
A band clamp is a tensioned fastening ring used to secure joints between housings, hose connections, or structural sections of a pump assembly. It applies even radial clamping pressure around the joint to prevent separation, leakage, or unwanted movement during operation. When a band clamp stretches, corrodes, or loses tension, the joint it holds can loosen — leading to fluid leaks, loss of suction, or accelerated wear on surrounding components.
