Piercing & ramming



Why Hercu tool is the best choice?

READY FOR HARD WORK CONDITIONS: Hercu Pneumatic's tools work in difficult conditions like mud , contaminants, water, etc.

  • Every Hercu model has a rubber lift valve (mudguard), which opens with machine's exhaust, and shuts-off afterwards. It makes difficult getting the dirt and other pollution into the machine. 
  • We have eliminated soft and sensitive Teflon®* seals and replaced them with hard steel surfaces achieved in special process. Hhardness of these surfaces is even 100 better than  Teflon®* seals. It makes our tools tight through for a long time of use.

HIGH EFFICIENCY: Hercu tools have high power to weight coefficent. Light weight tools can be used for higher profile works. The main profit of efficiency is saving time – very important in pipe ramming.

NON-SEALS TECHNOLOGY: All of the Hercu tools are  manufactured in NON-SEALS TECHNOLOGY. Susceptible Teflon®* seals have been eliminated and replaced by hardened steel surfaces. The benefit is that Hercu internal parts invariably keep their tightness. Our expearience says, that properly exploiting machines get worn minimally even after 2-3 years of operating.  Worn out internal parts may be sealed-up again as a result of low cost procedures. That process restores full power of the tool.

USE OF EXPANDERS: Hercu tools great asset is effective work with expanders - fast and convenient. We have eliminated unconvenient pulling using steel line. Easy on-off expanders fix system has not influenced degree of tool's wear.

PRICE: You can purchase an exellent quality tool with lower price.  Save 20-50% comparing to competitive products.

WIDE RANGE OF EQUIPMENT: Additional equipment is necessary to execute most of operations. Wide range of expanders, stretchers, ramming cones and other accesories gives you an opportunity to fully use the tool.

WARRANTY: Regardless of working conditions and run of tool, Hercu Pneumatic grants special tightness guarantee (for internal parts wear).
