The Wacker Neuson Suction Cover is a genuine OEM component designed for the PS3 and PS4 series submersible pumps, including the PS4-3703, PS4-5503, PS4-7503HH, PS4-7503HF, PS4-11003HH, PS4-11003HF, and PS3 5503 models across a wide range of voltage configurations. As a direct OEM replacement, this cover is produced to the exact tolerances and material specifications called out in the original Wacker Neuson design, ensuring a correct, secure fit every time. Fitment spans 220V, 440V, 575V, and 400V/50Hz variants within the PS series lineup, making a widely applicable service part for fleet operators and service shops alike. Keep a verified part number on hand to avoid the delays that come with sourcing incompatible covers in the field.
Key Features
- OEM-Matched Housing Geometry — Manufactured to the original Wacker Neuson dimensional spec, so the cover seats flush and seals correctly against the pump intake housing without rework.
- Broad PS Series Compatibility — Fits PS4-3703, PS4-5503, PS4-7503HH, PS4-7503HF, PS4-11003HH, PS4-11003HF, and PS3 5503 models across 220V, 440V, 575V, and 400V/50Hz configurations.
- Protects Intake Flow Path — A damaged or missing suction cover allows debris to bypass the intake screen, accelerating impeller wear and reducing pump output; this OEM replacement restores full intake protection.
- Genuine OEM Part — Sourced directly from Wacker Neuson, part number 5000150491 carries the same quality oversight as the original component installed at the factory.
- Multi-Voltage Fleet Coverage — A single part number covers an extensive range of PS series voltage variants, simplifying parts inventory management for operations running mixed-voltage pump fleets.
The suction cover on a submersible pump sits at the base of the unit and governs how water enters the pump intake. It works in conjunction with the intake screen to direct flow toward the impeller while blocking coarse debris that could cause internal damage. When the suction cover is cracked, warped, or missing, the pump loses controlled intake flow — resulting in cavitation, reduced discharge pressure, and accelerated wear on the impeller and volute. Replacing a damaged cover promptly restores proper hydraulic efficiency and protects the more costly internal components of the pump.
