Two-compartment system

The two-compartment system consists of an extra slosh plate that is welded in the front section of the tanker. Over the extra plate a pipe is placed with a blanking plate that connects the two compartments. The front compartment can be closed off from the rear compartment by means of a ball. When the tank is being filled, the ball will go up, as a result of which the entire tank will be filled. When it is being empties, the ball will come up through the hole, closing off the front compartment. This ensures an increase of the load pressure and traction while spreading the slurry. If the level is too low, however, the slurry will gradually flow from the front to the rear compartment, and the tanker can be emptied entirely.

A two-compartment system can only be supplied ex-factory.

Filler hole top of tanker with a hydraulic slide

Through a filler hole at the top of the tank it can easily be filled via an external pump system. The filler hole has a 600mm diameter and is operated by means of a double-acting cylinder. Thanks to the four bearings and the special cams on the filler valve it is pressed tightly into the rubber seal at the end of its cycle. This prevent any leakage.

A hydraulic filler hole can always be installed on PROFI I and PROFI II tankers. In other models a choice must be made between preparation or ex-factory assembly.

Top pressure cylinder

In addition to increasing the traction on the front wheels of the tractor, a top pressure cylinder also ensures more stable road-holding during transport. By placing the pivot of the cylinder close to the tractor it will always work in the direction of the tractor. This prevents extra sideways pressure on the traction when it takes a corner. It the tank is equipped with load-sensing hydraulics a special valve will ensure that the pressure in the top pressure cylinder will always stay around the predefined value.

A modified top pressure cylinder can be supplied for PROFI II tankers. In other models a choice must be made between preparation or ex-factory assembly.

KAWECO Rotocut stone trap

A stone trap will prevent clogging and protects the rotary lobe pump against foreign objects. Thanks to the large contents of the cutter, the slurry flow is slowed down, as a result of which heavy objects will be left at the bottom. Any feed or straw residue is cut up so small by the hydraulic cutter that it will pass effortlessly through the pump and the macerators. Every time the cutter is operated, it will change its rotary direction, so that the rotor plate will always remain spotlessly clean. The cutter blades have been preloaded by means of a spring and a nut on the hardox rotor plate. This way, they will be continuously sharpened, which guarantees their cutting capacity. For fast and easy emptying of the stone trap it is possible to manually open the cutter door, as an option.

A cutter can be supplied for the PROFI I and PROFI II. All PROFI III and DOUBLE TWIN shift tankers come equipped with 8" cutter. For the other models, you can choose for it to be prepared for the add-on or for an ex-factory assembly.

Additional 3-way valve for pumping

By installing an extra, manually operated 3-way valve in the pressure line immediately behind the pump, the slurry pump can be used externally and the tank can be emptied easily. The 3-way valve is mechanically operated and it is supplied with a side connection and quick coupling.

An additional 3-way valve is not available for PROFI I tankers.

Docking arm

A docking arm makes it possible to easily fill the tank without having to leave the tractor. For this you will need a docking funnel, which is placed stationery next to a slurry silo or pit. The benefit of a docking funnel is its limited weight and easy operation. The standard version of the docking arm has a range of approx. 1.5 meter outside of the tanker. At the end of the docking arm a hydraulic seal and a ventilation valve have been installed to prevent leakage.

For the PROFI I and PROFI II a docking arm can be supplied. For other models a choice must be made between preparation or ex-factory assembly.

Lateral slurry arm

To unburden the driver, KAWECO offers an ample choice of slurry arms. Every slurry arm is preferably placed on the right-hand side of the tanker, to create the shortest possible slurry route. The lateral slurry arm is available in a diameter of 8" or 10" and both with and without a Maxifiller (see Maxifiller description below). With the 8" lateral slurry arm, both pivots are operated by means of a cylinder, yet if extra coverage is desired, the top pivot can be fitted out with a hydraulic pivot. In all of these options a valve is installed to ventilate the slurry arm directly after filling. This allows the slurry to flow back from the pipe faster. As an option a guillotine shutter can be installed right below the maxifiller, which will seal of the slurry arm entirely, meaning it will not drip.

For the PROFI II a lateral suction arm can be supplied. For other models a choice must be made between preparation or ex-factory assembly.

Unloading via slurry arm

If the slurry, in combination with an ample pump capacity results in frothing, this is resolved by letting the spillage flow back into the slurry pit via the slurry arm. This ensures a better filling of the tanker, a larger capacity and less contamination of the farm yard. .

Swivel arm

By means of a swivel arm the range of the slurry arm is increased and allows you fill up both from a slurry pit and from a truck. The swivel arm is available in an 8" a 10" variant, which both have a swivelling range of 170⁰. For both variants, an option drip tray can be installed at the rear of the tanker. .

Overhead swivel docking arm 10" right-hand side

Especially for tankers that get slurry supplied to them, KAWECO developed an overhead 10" swivel docking arm. This arm makes the emptying of a transport easy as pie. Thanks to the broad horizontal range it is possible to reach next to the tractor's cabin. to make the arm even more flexible it can be extended up to approx. 5 meter beyond the tanker. To be able to guarantee a high pump capacity with this considerable range, the docking arm comes with a Maxifiller.

An overhead swivel docking arm can only be prepared or assembled ex-factory.

Overhead crane arm

Especially for sucking from slurry silo's or basins, KAWECO has developed an overhead crane arm. Thanks to the broad swivel range, this crane arm has a large degree of flexibility and manoeuvrability. Thanks to the standard double kink, the arm can also be used for sucking up slurry from slurry pits. To increase the range in depth, it is possible, as an option, to install a pivot in between the suction pipe and the Maxifiller. This makes it easier to guide the slurry arm into deep slurry pits.

For an overhead slurry arm a choice must be made between preparation or ex-factory assembly.


KAWECO advises to install a maxifiller to make the most of the pump capacity of your KAWECO tanker. This maxifiller consists of a hydraulic driven vane wheel that presses the slurry into the suction pipe, which decreases the negative pressure at the pump side (in PTW versions). The extra pump support offers many benefits that can be earned back fast. 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 life, because parts that will wear, i.e. bearings, rotor and seals will not be used as intensely. In vacuum tankers (VC variant) the maxifiller, in addition to increasing the filling capacity, also provides an increased filling degree of the tanker. This because the slurry is pressed into the tanker, so that it contains less air, thus filling the tanker better.

A maxifiller can be supplied for all KAWECO tankers.

Front axle can be extended by 750mm

As a sophisticated manufacturer when it comes to soil pressure, KAWECO offers a solution for lowering and improving the soil pressure for all of its slurry tankers. As a result, KAWECO has vast experience with extending axles. For all single, tandem and tridem tankers, KAWECO offers the option of incorporating one extendible axle. This extendible axle can be provided in two types, both with a 75cm extension. Depending on the type of tanker, the slurry and the working conditions, your KAWECO factory representative will be able to determine which axle is suited for your KAWECO tanker.

An extendible axle can be installed with all axle suspensions.

Electronic rigid steering

If your KAWECO tanker has been equipped with large tyres of if you opt for a larger tank volume in tandem, we strongly recommend that you have electronic rigid steering installed. This steering function by means of a potentiometer on the drawbar and an electro-hydraulic valve in the Load-Sensing system. This way, no additional power is transferred to the drawbar, and you can choose from various operating programmes.

Electronic steering can only be installed ex-factory, in combination with Load-Sensing hydraulics.

Axle lift front axle

For tandem and tridem tankers KAWECO offers the option to first relief the first axle. The axle relief is provided through an additional hydraulic cylinder that is connected to the hydraulic axle suspension of the other axles. This system does not allow for the overloading of the other axles.

An axle lift can only be in tandem or tridem tankers.

Automatic lubrication

To reduce maintenance and extended the life of the machine, we recommend fitting out your KAWECO tanker with automatic lubrication. KAWECO uses professional systems that are installed with great accuracy.

An automatic lubrication system can be supplied for all KAWECO tankers.

PTG air pressure exchange

If your KAWECO tanker is not only used in the field, we recommend that you opt for an air pressure exchange system. For this, KAWECO offers a complete, intelligent system that is suited for all tankers and applications. Depending on the desired working speed and the air chamber of the tyres, a 1000l/min or 3300l/min compressor can be opted for. As regards the air supply, it will be preferred, of possible, to drill the axles.This will provide air supply from the inner rim and will provide operational reliability under any circumstances.

An air exchange system can be supplied for all KAWECO tankers. We recommend opting for ex-factory for a preparation and drilled axles.

On-board hydraulics system

For special conditions or if the client desires, your KAWECO tanker can be equipped with an on-board hydraulics system. For this, a PTO from the tractor will drive a load-sensing pump, which in turn drives the slurry pump. The dosage of the slurry to the slurry spreader is based on a change of the pump speed, which will cancel the standard by-pass system.

On on-board hydraulics system can only be supplied ex-factory.
