Grundfos Unilift AP12 Series Submersible Drainage Pumps with Semi-Open Impeller

The Grundfos Unilift AP12 Series is a durable range of stainless steel submersible drainage pumps designed for pumping non-aggressive water, greywater, and lightly contaminated wastewater. Featuring a semi-open impeller, the AP12 handles solids and particles up to 12 mm, making it ideal for domestic and light commercial applications where efficient greywater removal is required.

This versatile pump can be used in both portable and stationary installations, making it perfect for applications such as basement drainage, sump pits, laundry water, or greywater systems in homes and small buildings. Built with high-quality stainless steel components, the AP12 delivers long service life, low maintenance, and reliable operation — even under frequent or prolonged use.

Applications include:

  • Greywater removal from showers, sinks, and laundry systems
  • Drainage of flooded basements or utility areas
  • Dewatering pits and tanks
  • Light commercial or residential use

Every Unilift AP12 pump is backed by Grundfos reliability and ships free Australia-wide from Land & Water Technology.
