Peristaltic Metering — Tube Failure Detection (TFD+)
The A-100N is a peristaltic metering pump that is self-priming even against maximum line pressure, cannot vapor lock or lose prime, and has no valves that can clog; its output volume is not affected by changes in back pressure. A variable-speed DC motor provides up to 20:1 turndown (model-dependent), and the patented Tube Failure Detection (TFD+) sensor senses tube failure and signals it through an alarm output. Tube choice sets the pressure rating and output range.
