Blue-White® FLEXFLO® A-100N
Metering Pumps
Variable speed motor delivers consistent continuous chemical feed
Patented Tube Failure Detection system shuts off pump in case of leak
Models available with 4-20 mA input for external pacing
FLEXFLO A-100N pumps are naturally degassing and self-priming, making them ideal for use with off-gassing chemicals like sodium hypochlorite. True variable-speed DC motors provide consistent chemical feed, minimizing pump maintenance and eliminating the need for mechanical starting/stopping. Heavy-duty NEMA 3R Valox® housing is chemical resistant.
Patented Tube Failure Detection (TFD) system halts pump operation in the event of tube failure. TFD system on pumps for chlorine and general chemicals uses a capacitive sensor to detect leaks. TFD+ system on pumps for polymer uses an optical sensor due to low conductivity.
Choose from two pump types. Manual pumps (A-100NF series) feature a speed dial on the front of the pump for manual feed rate control. External control pumps (A-100NV series) can receive 4-20 mA, 0-10 VDC and pulsed signal inputs from external devices like flowmeters or chlorine analyzers. Use these signal inputs to automatically adjust pump output.
Includes: two pump tubes, 5' each of PVC suction tubing and LLDPE discharge tubing, mounting kit, suction strainer, ceramic weight and injector. Optional MICRO-FLO flow verification sensors are available for external control pumps; see below.

Blue-White® FLEX-PRO® Metering Pumps
Self-priming even against pressures as high as 125 psi
Patented Tube Failure Detection (TFD) system protects the motor in case of a pump tube leak
2-year warranty
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; this allows 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.
Choose from a variety of models and features
Choose from pumps with tubing made from either Flex-A-Prene® (also known as Tygon®/Norprene®) or Flex-A-Thane® (also known as Versilon/Tygothane®). Select models feature an innovative double-barreled design that increases tube life to more than four times that of traditional tubes of the same throughput and pressure rating.
FLEX-PRO A2 metering pumps offer feed rates up to 357.6 gpd. They feature a user-friendly keypad and backlit LCD display that shows motor speed, service and alarm status, and input signals (on external control models). Choose from manual or external control models. External control models can receive 4-20 mA and pulse inputs for remote external speed control, and either powered or non-powered contact closure for remote start/stop. External control models also feature batch dispensing capabilities and alarm outputs.
FLEX-PRO A3 & A4 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. 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 Tube Failure Detection (TFD) system, Flow Verification Sensor (FVS) system, motor on, or operating mode error. The display also shows input signal values and units. Choose A3 pumps for feed rates up to 800 gpd, or A4 pumps for flow rates to 3804 gpd.
Additional voltages and feed rates are available as special order. Contact USABlueBook for more information.

Blue-White® CHEM-PRO® Diaphragm Metering Pumps
Smooth variable-speed drive—no hard pulses like with solenoid driven pumps
Full piston stroke every time avoids vapor lock
CHEM-PRO variable-speed diaphragm pumps feature a PVDF pump head and large PVDF double-ball valves— perfect for pumping difficult chemicals. Pumps feature a remote start/stop input and backlit LCD screen that shows motor speed percentage and alarm status.
Integral diaphragm failure detection system (DFD) and separate CHEM-SENSOR S6 flow verification sensors allow automatic pump shutoff if chemicals leak or flow stops unexpectedly. The built-in 3A alarm relay can then be used to trigger an external alarm.
Choose from two models. Manual control pumps feature a user-friendly 3-button keypad to adjust pump speed. External speed control pumps receive 4-20 mA and pulsed signal inputs from external devices such as flowmeters and chlorine or pH analyzers. Use the received signals to automatically adjust pump output. Use dual 4-20 inputs (speed and trim) for compound loop control. These pumps allow timed batch output trigger via single or multiple pulse inputs.
All pumps feature a NEMA 4X (IP66) washdown enclosure constructed from chemical-resistant powder-coated aluminum. Additional voltages and connections are available as special order; contact us for details.
Pumps include:
injection check valve assembly, foot valve/strainer, suction valve, discharge valve and 8' of PVC suction tubing.
Diaphragm kits include: replacement DiaFlex® diaphragm, PTFE reinforcement ring and backup washer.
