Water system

Always be on the safe side – with products from our range of sprinkling system parts: our reliable filters, high-quality pumps, spray nozzles, seals and couplings guarantee you trouble-free operations on hot asphalt .

Components

  • Spray nozzles:
    Each of the extremely water-efficient spray nozzles is fitted with fine sieves and is installed in a configuration that ensures complete wetting of the drums or tyres as required in all possible situations. Due to their positioning, they are protected against wind and can be watched by the operator during every job.
  • Water pump:
    Electric pressure sprinkling is taken care of by one or two alternately operating water pumps. While one pump is in use, the other is held in reserve as a backup.
  • Sprinkler bars:
    The sprinkler bars are designed as a quick-change system to make adjustment and maintenance work even more efficient. And, if frost is expected, the bars can simply be removed.
  • Antifreeze injection:
    The antifreeze injection option ensures that work can continue without interruption even at extremely low temperatures.
  • Plastic water tanks:
    The system’s plastic water tanks are integrated in the frame.
  • Driver Kits:
    The Driver Kits with genuine HAMM parts are particularly compact and take up very little space. This means that they can always be carried onboard the machine and allow, for example, the replacement of worn spray nozzles within just a couple of minutes.
  • Additive sprinkling:
    Optimised additive sprinkling for pneumatic tyre rollers enables an additive to be sprinkled onto the rubber tyres: The additive concentrate is simply poured into the additive tank of the machine without any need for pre-mixing. The dosage from the large additive tank with fill-level monitoring can be controlled from the operator's platform in a range of addition levels. The roller then automatically doses and mixes the additive during compaction in accordance with the specification. As the principle developed by HAMM avoids separation of the additive-water mixture, it also brings increases compaction quality. And last but not least, switching from water to additive can easily be done at any time directly from the operator's platform.

    WIRTGEN GROUP Asphalt Anti Stick additive is available in 5-litre and 20-litre canisters.

Adjustments and maintenance

When using the water pump, it is advisable to switch to the back-up pump every now and again to prevent pump failures caused by internal corrosion. If there is a risk of frost, you mustn’t forget to drain the pump at the end of the day’s work. Whenever necessary, the complete sprinkler bar assembly can be removed quickly and easily with the help of the quick-change system.

Check whether the water nozzles are working properly every day. In the case of blocked nozzles or nozzles with an irregular spray pattern, it is advisable to replace them as soon as you have the time.

Driver & Service Kits

HAMM offers a number of kits designed to make maintenance and the replacement of parts much easier. These kits contain all the most important replacement parts.

Kits with genuine HAMM parts are particularly compact and take up very little space. This means that they can always be carried onboard the machine and allow, for example, the replacement of worn spray nozzles within just a couple of minutes.

How to prevent wear affecting the sprinkling system

Use only clean water – this prevents clogging of water filters and unnecessary wear on pump and nozzles and ensures correct functioning of the sprinkling system at all times. Clean the filters in the sprinkling system at regular intervals to prevent premature pump failure. Nozzles blocked with asphalt residues should be cleaned or replaced as soon as possible.

Example of wear:

Intact nozzle

Blocked nozzle

Please note that unapproved water additives and / or separating agents can cause irreparable damage to the pump membrane and nozzles.
