The Wacker Neuson 5100031956 Suction Flange is a genuine OEM component designed for the PG1 Dewatering Pump. As a direct factory replacement, it meets the original engineering specifications and installs exactly as the original part, ensuring a proper, leak-free inlet connection. This is the same part supplied by Wacker Neuson during initial assembly, so you can be confident it will seat and seal correctly the first time.

Key Features

  • Genuine OEM Inlet Integrity — Manufactured to the exact dimensional tolerances required for a secure, leak-free seal at the pump intake port.
  • Direct Factory Replacement — Mounts to the PG1 Dewatering Pump inlet using the original bolt pattern and connection interface, requiring no adaptation.
  • PG1 Dewatering Pump Fitment — Confirmed compatibility with the Wacker Neuson PG1 Dewatering Pump (part number 5100031509).
  • Sustained Flow Performance — A properly sealed suction flange maintains full inlet vacuum, allowing the pump to draw and move water at its rated capacity without cavitation or flow loss.
  • Fuel and Fluid System Safety — A correctly fitted suction flange prevents air ingestion at the inlet, which can cause pump damage, irregular priming, and unsafe operation in dewatering applications.

The suction flange is the inlet fitting that connects the intake hose or pipe to the pump body, forming the entry point through which water is drawn into the pump. It creates the sealed pathway needed for the pump to generate suction and maintain consistent flow. When the suction flange is cracked, warped, or improperly sealed, air enters the system, disrupting priming and causing the pump to run dry — which can rapidly damage the pump internals and halt the dewatering operation entirely.
