Metering pumps


Blue-White Industries’ FLEXFLO® peristaltic pumps offer a self-priming and valveless (cannot vapor lock or lose prime) design, which is well-suited for abrasive, thick and gaseous fluids that can foul conventional metering pumps. The exclusive and patented Tube Failure Detection (TFD) system (US Patents 7,001,153 and 7,284,964) keeps both operators and pump rooms safe from spills. If a non-compatible chemical is detected in the head, the pump will automatically shut off and will not restart until that chemical has been removed. Other features include easy to re-order pump tube assemblies; feed output up to 5.17 gph (19.6 L/h); working pressures to 100 psi/6.9 Bar; digital models that accept 4-20 mA, 0-10 Vdc and pulse inputs for speed control, as well as a one-amp alarm output relay.
