The Wacker Neuson 5100031955 Pump Case Housing is a genuine OEM component designed for the PG1 dewatering pump. Sourced directly from Wacker Neuson, this is the same housing supplied on the original machine — no guesswork on fitment or compatibility. It installs as a direct replacement for the original, maintaining the precise internal geometry that the pump depends on to move water efficiently. If your PG1 is losing prime, showing signs of casing wear, or has sustained impact damage to the pump body, the 5100031955 is the correct part to restore it to working condition.
Key Features
- Genuine OEM Structural Integrity — Cast and machined to the original dimensional tolerances, ensuring the internal volute profile directs flow correctly and seals seat flush without gaps.
- Direct-Fit Replacement — Matches the original mounting bolt pattern and port configuration on the PG1, so it drops in without reworking surrounding components.
- Confirmed Fitment — Verified for the Wacker Neuson PG1 dewatering pump (machine number 5100031509).
- Preserves Pump Output — A damaged or worn case housing causes pressure loss and reduced flow rate; replacing it with 5100031955 restores the pump's rated discharge performance.
- Fluid-Tight Construction — The housing forms the primary pressure boundary of the pump; OEM material and finish standards ensure it withstands continuous operating pressures without seepage or cracking.
The pump case housing forms the outer shell of the pump's wet end, enclosing the impeller and directing water from the inlet through the volute and out the discharge port. It maintains the internal pressure necessary for the pump to draw water in and push it out at the rated flow and head. When the housing is cracked, corroded, or worn — particularly around the volute or seal face — the pump loses the ability to build pressure, resulting in reduced output, loss of prime, or complete failure to move water. Replacing a damaged housing with the correct OEM part is the most direct way to return the pump to full operating capacity.
