Grundfos Unilift AP12.40 SS Submersible Drainage Pump

Grundfos Unilift AP12.40 SS Submersible Drainage Pump

Reliable stainless steel dewatering for NZ wineries, cellars and vineyards

The Grundfos Unilift AP12.40 is a fully stainless steel submersible pump built for clean water and slightly dirty (grey) wastewater. It suits the daily demands of a New Zealand winery, from vintage wash-down and cellar floor drainage to tank farm sumps and irrigation dam transfer.

Choose your model from the variant selector:

  • AP12.40.04.A1 – The lighter-duty model. Good for barrel halls, cellar door and bottling hall sumps, and general wash-down water removal.
  • AP12.40.08.A1 – The higher-output model. Suited to busy crush pads, tank farm drains, larger sumps and higher lift requirements.

Both models have an integrated float switch (the "A" version), so pumping starts and stops automatically as the water level rises and falls. Use them as a portable pump or fixed in a permanent installation.
