The Wacker Neuson Retaining Plate is a genuine OEM component designed for the PS2-3703, PS3-3703, PS4-3703, PS3-5503, and PS4-5503 series submersible pumps. Sourced directly from Wacker Neuson, this part meets the exact tolerances and material specifications used in original production. It covers a broad range of voltage configurations — including 220V, 440V, 575V, and 400V models — across both 50Hz and 60Hz variants, making it the correct choice for a wide installation base. When it's time to service your PS-series submersible pump, using the correct OEM retaining plate ensures the internal assembly is secured as intended.
Key Features
- Genuine OEM Retention Integrity — Manufactured to the same dimensional and material standards as the original, ensuring the retaining plate holds internal pump components under continuous submersed operating loads.
- Direct Drop-In Replacement — Mounts in the same position and orientation as the factory part, with no reworking of surrounding hardware or housings required during installation.
- Broad PS-Series Compatibility — Fits PS2-3703, PS3-3703, PS4-3703, PS3-5503, and PS4-5503 submersible pumps across multiple voltage and frequency configurations (220V, 440V, 575V, and 400V / 50Hz and 60Hz).
- Maintains Internal Assembly Alignment — A correctly seated retaining plate keeps rotating and stationary pump internals properly located; a worn or missing plate can allow axial movement that accelerates wear on seals and impellers.
- Verified OEM Part Number — Part number 5000150520 cross-references directly to the PS-series service parts catalog, confirming correct application before you order.
The retaining plate is a structural fastening component within the submersible pump assembly, responsible for securing internal parts — such as the impeller stack or seal cartridge — in their correct axial position during pump operation. When the pump is running submerged, internal hydraulic forces push against rotating components, and the retaining plate provides the fixed reference surface that resists that movement. If the plate becomes damaged, corroded, or loses clamping integrity, internal components can shift, leading to reduced flow efficiency, accelerated seal wear, or mechanical contact between moving and stationary parts.
