HELIX 85, 85–2, 101

The eccen­tric screw pumps Helix 85, 85–2, 101 from BAUER are pow­er­ful rotary dis­place­ment pumps, which – in con­trast to the related, elec­tri­cal­ly oper­at­ed Helix­Drive – are driven by a tractor. The Helix 85, 85–2, 101 ensures a con­tin­u­ous speed-based flow that is nearly free of pul­sa­tion. Pump heads of up to 160 m can be achieved, making it pos­si­ble to spread slurry without dif­fi­cul­ty even in steep terrain. Another advan­tage is the minimal prepa­ra­tion time: set it up, switch it on and get started!

Ideal for steep terrain

With the BAUER eccen­tric screw pumps Helix 85, 85–2 and 101, liquid manure and slurry can be reli­ably spread even in severe terrain: The pumped medium is auto­mat­i­cal­ly drawn in from depth of up to 6 m, depend­ing on the con­sis­ten­cy. A pump head of up to 160 m is pos­si­ble, depend­ing on the pump type.

This pump is ideal for pumping slurry from the pit to a final storage place at a higher level or for umbil­i­cal systems in alpine areas.

The advan­tages of the over­pres­sure valve

For users who are par­tic­u­lar­ly con­cerned about safety, we rec­om­mend the over­pres­sure valve, which is fitted with a second con­nec­tion on the pres­sure side.

This offers utmost  pro­tec­tion in the event of block­ages or pres­sure shocks. The pres­sure line can be drained into the pit via the second con­nec­tion. As pro­tec­tion against dry running during suction or when the pit becomes empty, a build­ing water line can be con­nect­ed to the intake housing. The intake con­nec­tion (DN150) and pres­sure con­nec­tion (DN125) are option­al­ly avail­able with BAUER couplings.

Unique rotor
Rotor Bauer Exzenterschneckenpumpe

Unique rotor

The heart of the Helix 85, 85–2 and 101 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 
Bauer Güllepumpe HelixDrive

Excep­tion­al smoothness 

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

Proven quality

Proven quality

When it comes to quality, we do not com­pro­mise. In House factory pro­duc­tion guar­an­tees a con­sis­tent­ly high stan­dard of quality and the rapid avail­abil­i­ty of spare parts.
