Blue-White’s new TFD Plus system (Tube Failure Detection) is built-in to every FLEXFLO^® Peristaltic Metering Pump. There is no additional cost. The breakthrough technology of the TFD Plus detects the presence of oil and water-based polymers in the pumps’ head; which would indicate there has been tube failure. When the TFD Plus senses tube failure the pump automatically shuts off and will energize a relay; permitting communications with external equipment, such as a backup pump, an alarm or a SCADA system. There are no false warnings caused by condensation or washdown procedures. The peristaltic pump will not resume operation until the problem is resolved. The exclusive TFD Plus system is designed to eliminate costly polymer spills and down-time required for cleanup.  Blue-White is the only polymer pump manufacturer who can offer the genuine TFD Plus. Blue-White’s FLEXFLO^® Polymer Metering Pump is the only peristaltic pump that includes the TFD Plus. The peristaltic design of this pump uses rollers to compress the tube in a progressive squeezing action. This method of chemical delivery decreases regularly required maintenance because there are no valves that can clog.  The FLEXFLO^® Polymer Pump is self-priming even against maximum pressure. It will not vapor lock or lose prime.  The FLEXFLO has feed output up to 19.56 LPH and working pressures to 4.5 bar. The output volume is not affected by changes in back pressure. The Polymer Pump is designed with durable housing made of durable Valox (PBT) thermoplastic.  The easy to use digital touchpad has an LCD Display with service and alarm indicator icons. The LCD also displays motor speed and input signals.  There is a prime mode for easy priming without changing programming. (An analog display is optional.) Additional pump features include: easy to reorder pump tube replacements; the pump accepts 4-20 mA, 0-10Vdc, and Pulse inputs for manual and external speed control. Blue-White is ISO 9001:2015.
