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.

Extensive accessories

Extensive accessories

The BAUER helix eccentric screw pumps can be equipped with a range of attractive accessories such as:
