Sigma Tanker

The Slootsmid Sigma is a compactly designed slurry tanker mounted on a double-suspended axle. The large wheel arches allow for tires up to 2 meters in height to be fitted, significantly reducing soil pressure. Thanks to the steered rear axle and compact design, this tank, with a capacity ranging from 16,500 to 20,500 liters, remains highly maneuverable. The Sigma can be equipped with a vacuum pump or a lobe pump. It features load-dependent air brakes and European type approval for a road speed of up to 40 km/h.

Built on the Success of the Solid Series

The Solid slurry tankers have gained many satisfied users due to their high quality and excellent performance. The Sigma is designed based on the same principles and features a compact and robust design. The slurry tanker and chassis are constructed from 6-millimeter thick steel plates and fully galvanized. Thanks to the steered rear axle, the tank remains highly maneuverable, while the suspended axles ensure a comfortable driving experience. For enhanced comfort, the axles can also be equipped with hydraulic suspension, and a hydraulic drawbar suspension is available as an option.

Innovative Design for Low Soil Pressure

With its innovative design and large wheel arches, the tankers can be fitted with tires up to 930 millimeters wide. The large contact surface can be further increased with an optional tire pressure control system. The balanced weight distribution allows for high capacity while minimizing soil pressure.

Extensive Configuration Options

The new slurry tanker is available in capacities of 16,500, 18,500, or 20,500 liters, with all variants configurable with a MEC vacuum pump or a Börger rotary lobe pump. The chassis is prepared for the integrated Slootsmid lifting system, enabling easy mounting of virtually any injector. For precise application, a flow meter can be installed, and the slurry tanker can be equipped for fully automatic dosing. If desired, all functions can be controlled via ISOBUS. Additionally, provisions have been made for an 8″ suction arm, turbo filler, and macerator.

Options:

  • Hydraulic drawbar suspension
  • Hydraulic parabolic suspension on both axles
  • Hydraulically forced steering axle
  • Top link cylinder
  • 8” macerator
  • 8” turbo filler
  • 8” suction arm
  • Electric/hydraulic control
  • Flow meter
  • Fully automatic dosing
  • ISOBUS control
  • LED work lights
  • Tire pressure control system

Frequently asked questions

What are the main differences between the Solid and Sigma slurry tankers?

The Solid and Sigma slurry tankers are both robust and compact but differ in capacity and design.

Solid: Single axle, 10,000–14,000 litres. Lightweight, manoeuvrable and ideal for smaller fields.
Sigma: Tandem axle, 16,500–20,500 litres. More comfort and stability thanks to a steered rear axle and suspension. Perfect for more intensive use.

Both models are available as vacuum or pump tanks and can be equipped with a range of options.

Solid = agile and light. Sigma = powerful and comfortable.

Which slurry tankers best fits my operation?

That depends on the way you work.

The Solid is ideal if you mainly operate on smaller fields, cover shorter distances, and value manoeuvrability. It’s lightweight, easy to use, and requires little power.
The Sigma is better suited for more intensive use: longer distances, larger volumes, and contracting work. Thanks to its extra comfort and stability, it performs well even under tougher conditions.

This way, you choose not just based on technical specifications, but on what best fits your daily operation.
