Slurry tank PRONAR TG221
PRONAR TG221 slurry tank on a tandem chassis with a capacity of 21,000 litres. The plastic tank lowers the centre of gravity of the entire vehicle, which significantly increases driving stability. It is also lighter and, thanks to its special design and the use of a worm (cavitation) pump, no deposits form in this type of tank.
Pronar slurry tanks are fitted with worm pumps, which are characterised by high performance at practically no pressure, preventing the formation of so-called foam and, in the event of an uncontrolled increase in pressure, damage to the tank. The advantage of this type of pump, compared to traditional vacuum pumps used in steel tanks, is the efficient suction of sludge (even of high density) from lower tanks.
The excellent properties of the composite from which the tanks are manufactured result from the industrial-scale application of innovative vacuum infusion technology. It guarantees the very high resistance of the laminate, the reproducibility of the production and, at the same time, the creation of a product with high aesthetic qualities and very good strength parameters.
Composite tanks are also much more resistant to corrosion, which is extremely important when working in highly acidic environments. In addition, internal baffles have been built into the large composite tanks of Pronar’s slurry tanks to limit the simultaneous movement of too much liquid, thus guaranteeing stability and safety of transport, especially on public roads.

Standard equipment:
• European approval (according to European Parliament
and Council Regulation (EU) No. 167/2013)
• Composite tank reinforced with glass mats with internal transverse
partitions,
• Single-rotor auger pump with high suction and spreading capacity
driven from the tractor’s universal joint shaft,
• Suction valve 6″ (Perrot quick couplings and gate valve with hydraulic cylinder)
placed on the left side of the tank
• Two 6″ suction pipes (Perrot quick-release couplings), each 5 metres long (one pipe with a
basket to prevent stones from being sucked in)
• 6″ 3-way valve for switching mixing and spilling functions (with
hydraulic actuator)
• 6″ vent pipe
• Impact spreader (jet is directed downwards to reduce nitrogen losses)
• Barrel fill level indicator (on the front wall of the tank)
• Upper hatches (screwed on, with rubber seal)
• Central hydraulic system with electro-hydraulic protection system, electrically controlled (via console), wired from the tractor cab, performing the following functions:
– filling
– mixing
– pouring
– raising/lowering of the articulated suction arm of the docking mechanism (optional equipment)
– switching on/off the work lights
– luminous information on the dashboard about the activated functions of the hydraulic central system;
• Additional external control panel to operate suction/mixing functions
• The trailer requires a tractor with one pair of external hydraulic outputs to supply the central hydraulic system
• Telescopic PTO shaft (normal), for connecting the worm pump from the tractor universal joint shaft
• Reinforced chassis frame welded from 300x100mm rectangular closed sections, in high-strength structural steel, (frame suitable for mounting optional spreader attachments, suspended from 3- or 4-point suspension system or rigidly mounted)
• Hydraulically suspended drawbar with infinitely variable height adjustment for coupling to the tractor’s lower links (the system requires a permanent connection to one pair of the tractor’s hydraulic outputs)
