The FLEXFLO A-100N polymer pump from Blue-White Industries efficiently and accurately meters high-viscosity polymers. Its built-in tube failure detection system senses tube failure, automatically shutting off and energizing a relay or switch. This permits communication with external equipment, such as a backup pump or alarm. The pump will not resume operation until the problem is resolved. This eliminates costly polymer spills and downtime for cleanup, with no false triggering. It is self-priming, even against back pressure. Its tube assemblies are stamped with clearly visible part numbers for easy reorder. It offers precise chemical feed to 124 gph, with a max working pressure of 100 psi. The A-100NFP offers a variable-speed motor, dial knob control and on/off switch, while the A-100NVP comes with variable-speed motor, digital control with remote and local control. 714/893-8529; www.blue-white.com
