ALLIFT® Series
Elevating You to Pump Technology Excellence
The ALLIFT® series of high-performance three-screw pumps is primarily utilized in elevator technology, playing a vital role in driving hydraulic machines and elevators. The lightweight rotor housings are structurally optimized for minimal vibrations, made of an aluminum alloy. These three-screw pumps operate virtually pulsation-free and do not require a shaft seal, allowing them to be submerged directly in hydraulic fluid with a suitable motor. Tribologically optimized spindles provide extended service life.

This extensive range of flow rates enables you to choose the most suitable performance to satisfy your unique elevator and hydraulic needs.
Whether operating elevators, lifting platforms, theater stages, or other hydraulic machinery, ALLIFT® pumps bring you to the top.
