Magredi & Piave

Heavy duty sewer cleaning for sand, mud and rocks in flat pipes 

Heavy duty nozzle, sledge shape. Each of the 9 rear jets is bottom oriented with a different inclination, so that the water can reach the lateral parts of the pipe and give high traction to the nozzle. The sledge profile helps in overtaking obstacles and sedimentations with minor risks to get stuck. The nozzle has been specifically designed to be used with 200-300 lpm high pressure pumps. An additional weight is available for more stability. To be used with rotating swivel.

Magredi is ideal for

  • Heavy duty cleaning jobs: sand, mud, rocks
  • Round profile (DN>400) and flat pipes

Piave is ideal for

  • Suitable for portable jetters and low flow HP pumps
  • To be used for sand and sediments removal in small flat pipes
