Sizing tanks for PVC, PE, PP pipes CV, CV-2C, CV-D

Dual or single vacuum chamber sizing tanks for pipes with a diameter range of between 10 and 1000 mm.

The tanks are made of stainless steel, fixed to a steel base, equipped with independent automatic or manual devices for longitudinal and transversal position adjustment on the extrusion line.

The machines are equipped with a water system with thermostatic and valve controls which reduces the amount of water in circulation and keeps the cooling temperature constant.

Water is pressure-sprayed onto the pipe by spray sprinklers assembled on stainless steel bars; the spray angle is adjustable. Spray water is recycled and cleaned through a filter thus preventing clogging of the sprinklers.

An electrical motor, connected to a rail fixed to the floor, controls longitudinal movements.

Advantages of tanks with two chambers

  • Facilitate the extrusion process start-up.
  • Reduce initial waste and downtime.
  • Allow non-circular profiles to be sized.


  • Inspection hatches with toughened glass
  • Inlet and outlet watertight seal around the pipe
  • Low water consumption


  • Simple height adjustment
  • Strong, sturdy frame
  • Top quality materials used in construction
  • Filter with bypass keeps water clean
  • Special devices for longitudinal and transversal position adjustment
