UNILIFT AP 35 & 50 is available for automatic as well as manual operation and can be used in a permanent installation or as a portable pump. The pump is easily installed, as it is fitted with a carry handle and 10m mains cable.

The stainless steel pump sleeve is made in one piece, with a clipped on suction strainer, for easy removal, in case of maintenance.


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.

Handy and easily transportable
The carry handle mounted on the pump housing makes it handy and easily transportable.

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