Grundfos Unilift AP 12 Range

Introducing the Grundfos UNILIFT AP 12: a sturdy, submersible stainless steel pump, purposefully engineered for managing residential and light industrial rainwater and wastewater applications, including drainage and flood mitigation.

This rust and corrosion-resistant pump, constructed from top-quality, industrial-grade materials, offers unrivalled durability. With all key components made from 304 stainless steel, it guarantees longevity, even in challenging water conditions.

The Grundfos UNILIFT AP 12 is capable of operating while fully or partially submerged, thanks to a unique cooling jacket encasing the motor. This extends the pump’s operating time, ensuring it functions effectively even when it’s not entirely under water.

As a versatile solution for drainage and flood prevention, this pump can be set up as a permanent fixture or used as a portable unit to cater to changing needs. Whether you need to address regular drainage issues or manage unexpected flooding, this pump has got you covered.

The Grundfos AP 12 models we offer are equipped with a float switch, an invaluable feature for automatic water level detection and flood control, contributing to efficient operation in a variety of setups.

Installation is straightforward. Simply connect the pump to your drainage system, plug it into an electrical outlet, and you’re prepared for any water management tasks, including tackling flood risks.



The Grundfos Unilift AP 12’s Maximum particle size it can handle is 12 mm.
