Desilter Van Pack with radio control

The Harben® desilting system is based on the Harben® ‘P’ type radial piston pump.  Because the Harben® pump uses a high pressure diaphragm design it has the unique ability to pulse the high pressure water outlet and still withstand high shock loads created by the pressure wave.  We call this system the ‘Jump Jet’ and no other high pressure pump can produce the same results.

This pulse vibrates the desilting hose up to 20 times a second and in doing so reduces the friction of the hose against the wall of the cable duct.  The result is a desilting nozzle that can travel long distances into the duct, cleaning and unblocking as it goes, but which requires remarkably little energy to drive it.

The ability to desilt the duct with low flow and pressure has major advantages for telecoms contractors:

  • Distances up to 150m can be desilted from a single entry point
  • Low water usage means maximum operational time and maximum cleaning rate
  • Low water pressure removes the risk of damaging existing cables
  • Ducts can be roped ready for additional cables to be installed

The Harben® desilting system can clean ducts in up to 150m long and as a result hoses and hose reels have increased capacity to make the most of this extraordinary machine.

Flowplant engineers have worked with high pressure hose manufacturers to perfect a desilting hose that has great resilience, light weight, low friction and superb abrasion resistance and desilting nozzles with highly efficient ceramic inserts squeeze every last drop of power from the water jet.

The Harben® cable duct desilting system can be incorporated into some of our standard designs or used as the basis for a completely bespoke solution.
