The Wacker Neuson 5200020225 Cup is a genuine OEM component designed for APT4S and APT4T series trailer-mounted pumps. As a direct Wacker Neuson OEM part, the 5200020225 is manufactured to the same standards as the original, ensuring it installs correctly and performs as intended. This Cup is compatible across the APT4S and APT4T pump lineup, including standard, cold weather, surge brake, and electric brake configurations.
Key Features
- Genuine OEM Material Grade — Manufactured to Wacker Neuson's original material specification, so the cup maintains its sealing and retention properties under the operating pressures typical of trailer pump service.
- Drop-In Replacement — Matches the original mounting dimensions and interface points, allowing straightforward installation without rework or adaptation.
- Broad APT Series Coverage — A single part number covers the APT4S with skid, APT4S cold weather, APT4T surge brake, and APT4T electric brake variants, including their cold weather configurations.
- Supports Consistent Pump Output — A correctly seated cup maintains proper fluid containment and pressure integrity within the pump assembly; a worn or cracked cup can lead to leaks and loss of pumping performance.
- Verified OEM Part Number — Sourced directly from Wacker Neuson, so the part number 5200020225 matches your machine's parts documentation exactly.
A cup in a trailer pump assembly functions as a sealing or retaining component within the fluid circuit or bearing region of the pump. It creates a barrier that holds fluid in place and maintains pressure where it is needed, preventing bypass or leakage that would reduce pump efficiency. When a cup wears, cracks, or deforms, the result is typically fluid loss, pressure drop, or contamination ingress — all of which compromise pump output and can accelerate wear on surrounding components.
