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.

Excep­tion­al performance


  •  Abra­sion resis­tant, hard­ened smooth-running cupped rotors made of tough tool­steel – man­u­fac­tured by BAUER with a special tech­nol­o­gy and absolute­ly break-proof
  • Ther­mal­ly opti­mized bearing for con­tin­u­ous operation
  • Mechan­i­cal seal running in oil bath
  • Large dimen­sioned intake and pres­sure con­nec­tions to reduce plugging
  • Access eye in intake housing
  • Robust, per­ma­nent­ly lubri­cat­ed cardan joints
  • Compact foot­print
  • Chassis designed for quick and safe mounting
  • Quiet oper­a­tion


  • Easy to main­tain


  • Self priming


  • Per­ma­nent­ly lubri­cat­ed cardan joints beneath wear free, highly tear-resis­tant Elastopal sleeves
Compact design

Flex­i­ble and easy installation

Thanks to the extreme­ly compact design, the Helix­Drive can be easily inte­grat­ed into exist­ing systems The Helix fits com­fort­ably into exist­ing pump sumps. Instal­la­tion is par­tic­u­lar­ly easy: the entire unit is mounted on a sub­frame. There is no longer any need to screw or fix cast parts separately.

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.

Excep­tion­al smoothness

Excep­tion­al smoothness 

The light weight of the low fric­tion hollow rotor guar­an­tees con­sis­tent running smooth­ness in all speed ranges.
