Durable. Sturdy. Valuable.

Vacuum Tankers by Bauer

What is impor­tant to the farmer is a man­age­able tech­nol­o­gy, robust over many years and which meets the require­ments of the live­stock regard­ing cost-benefit ratio and the correct and proper dis­tri­b­u­tion of liquid manure.

BAUER slurry tankers have been a guar­an­tee of dura­bil­i­ty and lasting value for decades. Their reli­a­bil­i­ty and models adapted to the geo­graph­i­cal con­di­tions of use, give the Bauer slurry tankers their well-known image. A low centre of gravity qual­i­fies the vacuum tankers for moun­tain­ous regions and also results in incom­pa­ra­ble trail­ing behaviour.

All from one source

Bauer Group — the synergy advan­tage Thanks to its high level of in-house design and pro­duc­tion, BAUER offers per­fect­ly matched tanker com­po­nents. For this reason, the pro­duc­tion of com­po­nents within the Bauer Group offers a high level of tech­no­log­i­cal advancement.

  • BAUER com­pres­sors “Made in Austria”
  • Steel tanker pro­duc­tion from 1,100 — 28,000 litres
  • Control units devel­oped in-house, con­fig­ured for the Bauer tanker

BAUER Com­pres­sors

For decades, the BAUER com­pres­sor has been syn­ony­mous with reli­a­bil­i­ty and dura­bil­i­ty. High-quality lamel­lar graphite cast and the very precise machin­ing on CNC-con­trolled machin­ing centres enable a high degree of effi­cien­cy, which is reflect­ed in the world-famous suction and pres­sure char­ac­ter­is­tics. Every com­pres­sor has to prove its high per­for­mance require­ments for vacuum and pres­sure on the factory’s own test bench — only then is it deliv­ered to you.

  • Made in Austria
  • Silent, low power requirement
  • Low-speed engine — increas­es the already long service life even further
  • Envi­ron­ment-friend­ly thanks to low oil consumption
  • Durable through lubri­ca­tion both during vacuum and pres­sure operation
  • Forced lubri­ca­tion via piston oil pump

Devel­op­ment and Design

Our expe­ri­enced con­struc­tion engi­neers develop new com­po­nents and equip­ment focus­ing on well proven tech­nol­o­gy. BAUER slurry tankers are drawn in full 3D on CAD design work­sta­tions, ensur­ing that spare parts are avail­able even after many years. Test runs and load tests make sure that every pro­to­type is ready for series production.

Your con­fi­dence is based on our experience.

BAUER Vacuum Tankers

In a special process, the single parts of the tanker (rings of steel) are beaded and later put togeth­er with hydraulic presses to obtain a per­fect­ly round shape. Later on, the joints are auto­mat­i­cal­ly welded which ensures an opti­cal­ly perfect weld seam of high quality. The stan­dard hot-dip gal­va­niza­tion accord­ing to DIN EN ISO 1461 ensures long-term cor­ro­sion pro­tec­tion. The high-gloss gal­va­niza­tion with the typical “zinc flower” gives our tankers an amazing appear­ance. In order to pre­serve the appear­ance over many years, all gal­va­nized tankers are fin­ished with a special passivation.

Big wheels

No loss of volume

Wheel recess­es or wheel boxes reduce the volume. Not at BAUER! Due to the in-house pro­duc­tion of our tankers, the length of tanker is again enlarged approx­i­mate­ly to the nominal volume. The advan­tages of a recess in the tanker are:

  • The outer track can be reduced.
  • The steer­ing angle for tandem tankers can be enlarged.
  • The tanker volume can be iden­ti­fied simply from the BAUER type designation.

Depend­ing on the tanker type, the tractor and appli­ca­tion, the types of draw­bars offer dif­fer­ent advan­tages. There­fore, we are offer­ing the com­plete range:

  • Linkage above PTO
  • Linkage below PTO
  • Central drawbar

An option­al drawbar adjust­ment is avail­able for all draw­bars to adjust the tanker incli­na­tion or hitch height of dif­fer­ent trac­tors. An addi­tion­al exten­sion as a drawbar sus­pen­sion via nitro­gen accu­mu­la­tors is available.


Anti-surge Baffles
For your safety

Anti-surge Baffles

Big volume tankers require more road safety which is ensured by one or more anti-surge baffles, depend­ing on the tanker size. Anti-surge baffles are a stan­dard in all models from size 55 up.



The insen­si­tiv­i­ty to foreign matters in the slurry is one of the strengths of the vacuum tanker. However, this requires good acces­si­bil­i­ty to the tank. For this reason, we man­u­fac­ture a tanker lid which can be opened com­plete­ly up to a tanker diam­e­ter of Ø1250mm and a recessed manhole from a tanker diam­e­ter of Ø1400mm. The manhole with Ø750mm com­bines the advan­tages of good acces­si­bil­i­ty and low effort with only a few screws to open. Easy maintenance.

  • From model 55 manhole cover Ø 750mm

For com­pres­sor and tanker

Bauer vacuum tankers are pro­vid­ed with a double over­pres­sure pro­tec­tion in stan­dard exe­cu­tion. A sealed pres­sure relief valve with blow-off hose reg­u­lates the pres­sure and the spring-loaded dome lid pro­vides double pres­sure pro­tec­tion in the tank.

Ball valves in the dome and in the siphon provide double safety against slurry enter­ing the com­pres­sor.  The under- and over­pres­sure can be read from the glyc­er­ine manovacuumeter.

  • Double pres­sure pro­tec­tion as standard
  • Double ball valves as standard

Prepa­ra­tion for ground-level spread­ing technology

With the option­al prepa­ra­tion for hose appli­ca­tor, Bauer vacuum tankers can be equipped for hose appli­ca­tors or trail­ing shoe appli­ca­tors. The pos­si­ble para­me­ters are already taken into con­sid­er­a­tion in the design and the tanker is equipped accordingly.

The effec­tive filling aid


The flow-opti­mised cast pump housing, adopted from BAUER pumping tech­nol­o­gy in which an impeller insen­si­tive to foreign bodies runs at high speed, con­sid­er­ably sup­ports the normal suction process. The com­pres­sor can be run at low speed. This makes the vacuum tanker almost com­plete­ly full again and reduces the filling time.

Air power
Air power

Air Mixing Device

The slurry is agi­tat­ed in this area by air flowing in via sleeves. Check valves protect the com­pres­sor. Tankers with a com­pres­sor size of B33 to B83 are equipped with one mixing tube. As from com­pres­sor type Star, two mixing tubes are installed.

Down­hill Spreader
Com­plete emptying

Down­hill Spreader

When driving down­hill, a vacuum tanker cannot be emptied com­plete­ly for reasons of the system. The down­hill spread­er allows to select the spread­ing sit­u­a­tion and to empty the tanker completely.

Auto­mat­ic Suction
Fast. Effec­tive. Clean.

Auto­mat­ic Suction

And without getting off the tractor. With a suction arm (auto­mat­ic suction), you hydrauli­cal­ly dock the suction line into a suction funnel placed on the slurry pit/lagoon. You start/stop the filling process direct­ly from the tractor via hydrauli­cal­ly con­trolled suction slides. Dif­fer­ent types of suction arms are available.

SLE System
For ver­ti­cal load upholding

SLE System

The system based on two tank cham­bers auto­mat­i­cal­ly empties the rear chamber first whereby the first one always receives the full ver­ti­cal load. This allows for better trac­tion on the tractor wheel and for safe driving off-road. Avail­able as from type V77.

Hose Appli­ca­tor & Trail­ing Shoe Applicator
Pre­pared for

Hose Appli­ca­tor & Trail­ing Shoe Applicator

This allows a sub­se­quent attach­ment of a spread­ing boom at any time. In this case, the tanker is equipped with a flat manhole so that the spread­ing device can be attached as closely as pos­si­ble to the tanker body. Fur­ther­more, an addi­tion­al outlet flange for the feed line of the spread­ing boom is placed at the top rear of the tanker.

Our vacuum tankers are also avail­able in tandem execution.

V100 4-Federtandem (6)
Four-Spring Tandem

Tandem Chassis Technology

Vacuum tandem tankers from 10,000 litres have been equipped with the proven 4‑spring tandem group for many years now. Sturdy sus­pend­ed par­a­bol­ic springs com­bined with the com­pen­sat­ing rocker and, on large series, with addi­tion­al lon­gi­tu­di­nal sta­bilis­ers provide driving safety and high load-bearing capac­i­ty. From size V100TL, a self-steer­ing on the second axle is includ­ed as stan­dard. This ensures low tyre wear and soil pro­tec­tion in the field.

Axle Groups

Type series V63T to V81TL are equipped with spring-loaded bogie axle groups.

Star Com­pres­sors

Pumping Tech­nol­o­gy

In tandem vacuum tankers from 12m³, the first-class Star com­pres­sors used are opti­mal­ly matched to the tanker volumes and ensure the maximum tech­ni­cal vacuum for effec­tive suction.
