FLEX-PRO metering pumps feature a variable-speed DC motor for consistent chemical feed without mechanical starting and stopping. The innovative Tube Failure Detection (TFD) system eliminates the risk of running the pump motor if the pump tube leaks. If leaked chemical is detected inside the pump head, the pump stops and its programmable alarm relay closes; allowing for remote alarm indication or initiation of a back-up pump. All pumps feature a NEMA 4X (IP66) wash-down enclosure constructed from chemical-resistant powder-coated aluminum.

FLEX-PRO A3 metering pumps feature a user-friendly keypad and a 3-color VGA backlit LCD screen that shows % of motor speed plus service and alarm status. Pumps feature external control; control pump output manually or with 4-20 mA, 0-10 VDC or pulse signals. A 30 VDC contact closure for remote start/stop is also included. Three 30 VDC or 115 VAC contact closures are assignable to monitor TDS system, Flow Verification System, motor on, or operating mode error. The display also shows input signal values and units.

Use with polymers. Call for compatibility with other chemicals.

Wetted materials: Flex-A-Thane (also known as 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 FKM O-rings.

Includes: two pump tubes, PVDF injection fitting, 10' roll each of 3/8" OD suction and discharge tubing, foot strainer and 2-year warranty.
