VARIJECTOR® Jet Pumps, Blowers and Injectors

Varijector® jet pumps are ejectors driven by an interior ring nozzle, with free unblocked passage between the vacuum inlet and the blowing air outlet of the ejector pump. The pumps are driven by compressed air or other gases (e.g. Nitrogen). The compressed air is blown through a ring gab an directed diagonally inward in vacuum-flow direction. High turbulences of the blowing air catch surrounding air, both are blown into a internal diffuser nozzle.

Varijectors are available with inner diameters from Ø 5 to 50 mm and reach a maximum vacuum from -10 to -70 kPa.

They are generally suitable for injecting bulk materials and gases, for low positive pressure blow conveying, for mixing gases, for the textile fabric handling (threads), for wire and tubing drying process and for producing high volumes of blowing air, as they multiply the used compressed medium (e.g. for blowing of sheets, papers, cooling and process technique).

The ring-nozzle inside Varijector jet pumps is freely adjustable. So vacuum, air consumption and mixing ratio can be adjusted in a wide range freely.

VOLKMANN Varijectors are available in different materials e.g. in aluminium, stainless steel, high temperature steel, PE, PP.

Individual designs with special diameters and materials can be manufactured upon request.
