Grundfos Unilift AP35B/AP50B


UNILIFT AP Basic pumps are single-stage pumps with a vortex impeller. The pumps are designed for pumping dirty water, untreated waste water containing particles up to a size of Ø50 mm, depending on the pump size. All UNILIFT AP Basic pumps are made of stainless steel with a composite base plate. The UNILIFT AP Basic range is designed for submerged operation, either free-standing or on the base plate. In addition the pumps are suitable for installations on auto couplings, which allows easy access to the pump for maintenance and other purposes. All UNILIFT AP Basic pumps can be supplied with or without float switch, for automatic or manual operation.



Robust design

The materials of the pump ensure excellent corrosion resistance. The pump housing and impeller are made of high quality stainless steel. Furthermore, the mechanical shaft seal offers high-wear resistance and a long operating life.


Thermal overload protection

The single-phase version is effectively protected against any accidental overload by built-in thermal protection.
This means that no additional motor protection is required.


Option for automatic operation

The pumps are available with float switches for automatic on/off operation.


Auto coupling

UNILIFT AP Basic pumps are suitable for installation on an auto coupling at the bottom of a collecting tank with guide rails going to the top. A guide rail system is available from Grundfos as an accessory.
