Pumps & Conveying System Components Chapter 2: Functional Description 12
Basic System Types
Time-Fill Systems
A time-fill system conveys material to an on-line vacuum receiver for a pre-set time period.
When this interval elapses, the controller conveys material to the next on-line vacuum
receiver.
Volume-Fill Systems
A volume-fill system conveys material to an on-line vacuum receiver until the material level
activates the proximity switch in the vacuum receiver, or a preset time elapses. When either
of these conditions occur, the controller conveys material to the next on-line vacuum receiver.
Equipment Cycle
Our bulk material conveying systems are used for automatic pneumatic handling of most
free-flowing, dry, pelletized, powder granular materials.
Material characteristics determine the type of equipment needed to properly convey the
material.
See Figures 7 and 11 on Pages 25 and 28 for typical system configurations.
