The electrically driven eccentric screw pump HelixDrive, which is ideal for stationary use in agriculture and industry, is the optimal solution for customers with high demands. The possible application spectrum of this pump ranges from liquid manure and sewage sludge to molasses.

The heart of the HelixDrive is the lightweight hollow rotor manufactured in a unique process in the BAUER factory. It is absolutely unbreakable and guarantees the smoothest possible running. Thanks to the 100 millimeter rotor, optimal performance can be achieved even at relatively low speeds and consequently low wear rates.

Unique rotor

The heart of the HelixDrive is the low friction hollow rotor the key component of every eccentric screw pump. This rotor is manufactured in a unique special process at BSA, a BAUER Group company, and is absolutely break-proof.

Longer durability

Longer durability

Tough tool steel and a consistent wall thickness of 8 mm prevent heat accumulation and stress cracks. The special coating applied makes for a tough and smooth surface. This process also ensures a longer life of the stator rubber, as the smooth rotor surface causes considerably less abrasion.
