FLEXFLO® Peristaltic Metering Pumps have an impressive edge over other manufacturers peristaltic units. Only FLEXFLO pumps are available with
Blue-White’s Superior Patented Pump Tube Design and the Patented Tube Failure Detection System. Peristaltic Metering Pumps are well suited to metering fluids that could foul heads with conventional check valves. Peristaltic Pumps have roller assemblies that compress the pump tube in a progressive
squeezing action.

Standard Model A-100NC - FIXED SPEED UNIT
with Time Interval Control

FEATURES INCLUDE:
• Precise output control to 20:1 turndown by means of a dial knob.
• Adjustable 5 second repeating interval timer (0.25 - 5.0 sec) results in a high
afrequency of small injections per minute.
• Patented TFD (Tube Failure Detection) system protects against chemical spills
afrom a worn out tube and activates an open collector alarm output.
• Custom programmed total time / on-time ranges available, call sales department.

TFD – Tube Failure Detection System
The TFD System is breakthrough technology for Peristaltic Metering Pumps. Blue-White was the first to introduce this type of feature on peristaltic pumps, and the only manufacturer able to offer the Patented TFD System (U.S. Patent 7,001,153). The TFD System is able to detect a wide range of chemicals (i.e. chlorine, acids, soaps, etc.). This exclusive technology was designed to disregard pump compatible fluids; such as water and lubricants. If there is a rupture in the pump tube, and a chemical is detected in the pump head, the pump will automatically shut off and energize a relay, permitting communications with external equipment, such as an alarm or a SCADA system. The chemical must be cleaned from the pump head before the pump will restart. The TFD System is a Standard Feature on Blue-White’s
FLEXFLO and FLEXPRO Peristaltic Chlorinators.
