Kaweco - Model PROFI III-Series -Slurry Tanker

Undercarriage and tanker construction
Not just the weight of the applicator but also the distance behind the tanker determines how heavy the burden on the chassis will be. With more than 50 years of experience in manufacturing and engineering, KAWECO knows how to solve these aspects. The chassis of a PROFI III tanker is the only one who’s specially constructed to transfer the lifting-power to the tractor. Because of the six twist locks the tanker is mounted to the chassis tension free. Whether the chassis undergoes traction or pressure forces, the tanker is mainly used for carrying the slurry. This is why the tanker can have a lighter construction, which will benefit the total weight of the machine.

Hitch
All tankers from the PROFI III series are equipped with the heavy KAWECO Premium hitch. The hitch is fully mounted to the chassis so that there will be no force on the tanker. The lifting cylinders are adjustable in terms of pressuring and relieving pressure. Thanks to the standard control of the hitch at the back of the tanker and the link hooks to the lift bars, the attaching of an applicator is very simple.

Undercarriage
All PROFI III tankers are equipped with a hydraulic axle suspension and a load-independent suspension system. This suspension system has two large spring accumulators that always ensure optimum suspension, whatever the weight of the machine. As an option, the front axle can relieved of pressure, both in tandems and three-axle machines. If load is taken off the axle, the other axles can never be overloaded. All PROFI III tandem tankers have hydraulic forced steering of the rear axle and the PROFI III tridem tankers are steered on the front and the rear axle (all three axles optional). The hydraulic forced steering is controlled via a cylinder on the drawbar or, as an option, via an electronic potentiometer and the standard Load sensing hydraulics.

Pump and slurry piping PTW tanker
Advantages of the PTW-tanker are: precise dosing and high filling capacity. The filling of the tank remains guaranteed, regardless of the thickness of the slurry. In addition, the filling capacity is better maintained with greater suction depth. Possible limitations of the PTW-tanker are: relatively high maintenance costs and more wear and tear. The weight of the machine is also increased by the required piping.

Slurry route and stonecatcher
Every tank of slurry that is transported or unloaded will have to be filled first. Throughout the entire process, the filling capacity mostly depends on the slurry route and on the position of the pump, the pipes and the stonecatcher. The position of a KAWECO pump is always central. In the middle, underneath the tanker. This results in the shortest possible slurry route with fewer unnecessary bends and a central distribution of the weight. With an adjustment of the pipes you can work with maximal capacity if wanted. KAWECO always uses 8″ pipes to the suction side and maximum two times 6″ to the pressure side. If the pump capacity is increased, the pipes will be larger too. Therefore, a 9,000 l/min pump always comes with a 10″ filling piping and two 8″ pipes on the pressure side. The tank gets filled by the double pipes at the pressure side because of the automatic opening of the By-Pass.

Pumps and filling arms
To unburden the driver, KAWECO offers a broad selection of filling arms for the PROFI III series. Every filling arm is preferably placed on the right-hand side of the tanker to create the shortest possible slurry route. In addition to a side filling-arm, KAWECO also provide many crane of swivel arm options. In most cases, KAWECO advises to mount a maxifiller to be able to use the highest capacity possible. This maxifiller contains a hydraulic driven vane wheel that presses the slurry into the suction pipe, which decreases the negative pressure at the pump side. The extra pump support offers many benefits. For example: the negative pressure is strongly reduced, meaning that the pump does not have to suck up the slurry as intensely. This will improve the machine’s lifespan, because parts that will wear, i.e. bearings, rotor and seals, will not be used as 

KAWECO ISO-BUS control
All PROFI III tankers are operated via KAWECO premium control. This control terminal offers many, conveniently arranged options. All systems are equipped with a multifunctional joystick with 24 functions and a 5,7″ Basic Terminal. As an option, we offer an 8″ or an 11″ Touch Terminal, and the PRO joystick.

Weighing and sampling
Thanks to the unique, independent construction of the chassis and tanker all PROFI III tankers can be equipped with a weighing and sampling cabinet. The robust weighing cells are placed in between the chassis and the tanker, using a special assembly process. This way, the height of the tanker and the construction method of the slurry route will not be influenced.

Tyres, wheels and soil pressure
Thanks to the unique construction method the KAWECO PROFI III tankers are very soil-friendly. If so desired, you can opt for a tyre with a 1,800 mm diameter and a width of 800 mm (optionally up to 900 mm). These tyres ensure a larger ‘footprint’, which means the soil won’t be pressured much. To be able to make optimum use of these types, your KAWECO PROFI III can be fitted out with a tire inflation system. This system can be combined with the control computer to simplify operations.

Options for Profi III
Despite the very complete standard set-up of the Profi III tankers there are many options for equipping your KAWECO PROFI III as you like it. Think about traction-increasing options like a Top pressure cylinder or a two-compartment system. See the most common options below.
