FLEXFLO A1 pumps are naturally degassing and self-priming, making them ideal for use with off-gassing chemicals like sodium hypochlorite. Their brushless DC motor runs cool while reducing overall energy usage—great for continuous duty applications. The 2000:1 turndown ratio delivers high-precision pumping.

A1 pumps use the same proven pump tubes and rollers as the popular Blue-White A100 series. A patented Tube Failure Detection (TFD+) system halts pump operation in the event of tube failure. TFD+ uses an optical sensor that is compatible with most chemicals, including polymers.

A digital keypad interface makes it easy to manually adjust output. Pumps also feature inputs for flow verification and remote on/off, plus two outputs to accommodate a relay and alarm (requires M12 cable kit, sold separately below).

External control pumps (A1V series) accept a 4-20 mA input signal, which allows an external device like a flowmeter or process analyzer to drive feed rate control.

Use with polymers (call for compatibility with other chemicals). Wetted materials: Flex-A-Thane® (AKA Versilon™ or Tygothane®) pump tube with PVDF adapter fittings, PVC suction tubing, polyethylene (LLDPE) discharge tubing, polypropylene suction strainer, PVDF injection check valve, ceramic check ball, Hastelloy C-276 spring and PTFE/FKM O-rings.
