Pneum. conveying technology - Pressure vessel conveyor Type T

The proven conveyor to transport dry, granular and free-flowing bulk material in a current of air under pressure.

KLEIN pressure vessel conveyors type T are used in the following industries: foundry and steel, chemical and pharmaceutical, glass and ceramics, food and animal feeds, quarry and earth shifting, and sand feeding systems for rail vehicles.

Flow takes place in cycles, alternating between filling, and conveying from, the pressure vessel. Compressed air pushes the granular or bulk material out of the pressure vessel through a conveying pipe. In this process the end of the pipe immediately after the pressure vessel, is filled over the full cross section. Depending on the adjustment of the system and the properties of the conveyed product, a series of plugs is formed, and the distance between these will increase as the conveying distance increases. There is, however, no dispersal effect.

During each conveying cycle, solely the content of the pressure vessel is released into the conveying pipeline. The conveying pipe remains filled so that each conveying cycle is started against a full pipe. Thus, wear and material abrasion are considerably reduced.

Conveying plants equipped with a KLEIN pressure vessel conveyor type T make up a closed system and operate almost free of abrasion, wear and similar undesirable interaction. They are compact, easy to maintain, and generate little noise.


  • Dust tight coupling of inlet tube with axial and angular adjustment: no dust can escape; easy to install
  • Large cross section of the inlet with conical closure; short filling time
  • Block design: the pneumatic control unit can also be separated from the conveyor
  • All electrical connections wired to one terminal strip for easy installation
  • Robust valves for the control
  • 3 point mounting for easy, safe positioning, avoiding the need for a complex support structure
  • Can be operated automatically or manually to match operational requirements
  • Low wear and maintenance: no moving parts to come into contact with the material to be conveyed
  • Easy to maintain
  • Low air consumption for the conveying function: economical; only small filters are required at the receiving tanks
