FlexFlo A-100NA 114N 115V -7T 1 MIN

The Blue-White Industries FlexFlo A-100NA (Model A-100NA-114N / A-100N Series) with -7T Flex-A-Prene Tubing and 1-Minute Cycle Timer is a commercial-grade, self-priming peristaltic metering pump engineered for high-output, low-to-medium pressure chemical injection in commercial aquatic facilities, water treatment plants, and industrial processing.

Equipped with the high-capacity #7T Flex-A-Prene tube assembly and an internal solid-state repeating duty-cycle timer operating over a 60-second window, this model delivers up to 98.0 to 100.0 GPD (Gallons Per Day) against system backpressures up to 30 to 40 PSI. Paired with Pool Link 500/1000 Series automation controllers, it is standard hardware for high-demand bulk sodium hypochlorite (12.5% to 15%) and muriatic acid (31.45%) dosing loops on commercial pools, lap pools, and waterparks.

Nomenclature & Model Decoding

• FlexFlo A-100NA: Blue-White peristaltic metering platform with analog electronic cycle-timer regulation.

• 114N: Hardware electrical and drive configuration:

  • 11: 115V AC / 60 Hz electrical service (pre-wired with NEMA 5-15 3-prong grounded plug).

  • 4: High-output planetary gear-motor drive package.

  • N: Standard non-programmable analog electronic control module.

• -7T: #7T Flex-A-Prene (Santoprene-grade) heavy-wall pump tube assembly with 3/8" OD compression connection fittings.

• 1 MIN (1-Minute Cycle Timer): Internal solid-state percentage duty-cycle timer indexed over a continuous 60-second time base (approx. 0.6 seconds to 60 seconds of run-time per minute).

Mechanical Architecture & Operational Dynamics

• Solid-State 1-Minute Cycle Timer: Features an analog potentiometer dial indexed from 1% to 100%. Every 60 seconds, the pump energizes the roller drive for the selected percentage of the minute and shuts off for the remaining duration (e.g., at 25%, the pump runs for 15 seconds and rests for 45 seconds). This prevents line shock and overdosing while allowing fine output throttling directly on the pump.

• Gas-Binding & Vapor Lock Immunity: The peristaltic roller compression continuously forces off-gassing oxygen bubbles ($O_2$ from liquid chlorine) and fuming hydrochloric acid vapors ($HCl$) through the feed tube, eliminating the air-binding common to electronic diaphragm metering pumps.

• Self-Priming & Natural Anti-Siphon Barrier: Capable of pulling a vertical suction lift up to 30 feet of water. The planetary rollers maintain constant, mechanical pinch-closure against the tube track, preventing chemical siphoning into the pool return loop without requiring separate spring-loaded backpressure valves.

• Chemical Isolation: Corrosive fluids contact only the inside of the #7T Flex-A-Prene tube, polyethylene suction/discharge piping, and injection check valve quill, keeping motor windings and drive bearings completely isolated.

Technical Specifications

• Max Output Capacity: Up to 98.0 – 100.0 GPD (approx. 4.08 – 4.17 GPH / 257 – 263 mL/min / 371 – 378.5 L/day) at 100% continuous runtime.

• Turndown Range: 1.0 to 100.0 GPD (1% to 100% duty cycle via the 60-second cycle timer).

• Maximum Working Pressure: 30 to 40 PSI (approx. 2.07 to 2.76 bar).

• Electrical Service: 115V AC, 60 Hz, 1-Phase, 0.5 A max operating draw.

• Pump Head Tube: #7T Flex-A-Prene Tube Assembly with quick-disconnect compression nuts.

• Suction / Discharge Plumbing: 3/8" OD UV-resistant white opaque or clear braided polyethylene tubing.

• Duty Cycle: Intermittent duty-cycle rated; fully compatible with external powered relays or dry-contact outputs from Pool Link 500/1000 Series controllers.

• Operating Ambient Limits: 14°F to 115°F (-10°C to 46°C); process liquid temperature up to 130°F (54°C).

Maintenance & Consumables

• Tube Replacement Interval: Replace the #7T Flex-A-Prene tube assembly every 500 to 1,500 run hours (or every 4 to 6 months in heavy commercial facilities).

• Roller Assembly Care: Inspect and clean the planetary rollers during each tube change; lubricate the inner race with silicone or synthetic grease to reduce friction against the outer tube jacket.

• Injection Check Valve Maintenance: Clean or replace the duckbill injection quill every 6 months to remove calcium scale and mineral crusting at the pressurized pipe tap.
