The Wacker Neuson Screw is a genuine OEM component designed for the PS2, PS3, and PS4 series submersible pumps, spanning models from the PS2-1503 through the PS4-11003HH and PS4-11003HF. Sourced directly from Wacker Neuson, this is the same screw specified in the original factory build — not an approximation. It fits an extensive range of PS-series pump configurations, including 50Hz and 60Hz variants across 2-inch, 3-inch, and 4-inch discharge sizes, making it a go-to stocking part for fleets running multiple pump models.
Key Features
- Genuine OEM Thread Integrity — Manufactured to the exact thread form, drive type, and tensile specification called out in the Wacker Neuson parts schematic, so fastener engagement is correct from the first turn.
- Direct Drop-In Replacement — Installs in the same position and orientation as the original hardware with no reworking of mounting holes or mating surfaces.
- Broad PS-Series Compatibility — Fits PS2, PS3, and PS4 submersible pump models from the PS2-1503 up through the PS4-11003HH and PS4-11003HF, covering both 50Hz and 60Hz electrical configurations.
- Maintains Structural Clamping Load — A correctly torqued screw keeps pump housing panels, covers, and internal assemblies seated under continuous submersed operation; a worn or incorrect fastener can allow ingress or component movement that leads to pump failure.
- Part Number Confidence — Part number 5100028211 is the active Wacker Neuson OEM reference, so you can cross-check it directly against your pump's parts manual before ordering.
A screw in a submersible pump assembly does more than hold panels together — it maintains the clamping force that keeps sealing surfaces compressed and internal components properly aligned during continuous operation under water. When a screw stretches, strips, or corrodes, it can allow housing sections to shift or separate, breaking the seal integrity and exposing motor and impeller components to water ingress. Replacing a damaged or missing fastener promptly with the correct OEM-spec part is one of the simplest ways to protect the broader pump assembly and keep discharge performance where it needs to be.
