Circulation pump ZPE 800

Advantages of the BRAWO® circulation pumps

  • Increased safety during liner installation, thanks to faster and more-uniform distribution of heat
  • High efficiency thanks to short curing time
  • More reliable installation

During the hot cure process, the BRAWO® HotBox is connected to the inversion drum and warm water is then passed into the liner. Once the curing water is at the correct temperature a special pump, designed for use with hot water, is used to re-circulate the water through the liner and the circulation pump.
