Due to its special function of, it can operates in the harsh conditions more reliable, superior, more economical and more efficient. Most important is no destroy to the media. Suitable for conveying different viscosity of the medium and high viscosity of the medium, particles containing particles which need to be protected from destruction and media that should be soft transported and not fit for high impact. Application: Suitable for conveying different viscosity of the medium and high viscosity of the medium. Containing Solid particles as much as 75% (Can be designed to the requirement of 3 0-80MM particles) and the media need to protect against particle from destroyed medium that containing gas or air as 68%. Cotton pulp, wood pulp containing various Fiber. Media should be soft transport and the media should not fit for high impact and Sewage waste.
