FlexFlo A-100NA 145N 115V -6T 1 MIN

The Blue-White Industries FlexFlo A-100NA (Model A-100NA-145N / A-100N Series) with -6T Flex-A-Prene Tubing and 1-Minute Cycle Timer is a commercial-grade, medium-to-high capacity peristaltic metering pump engineered for precise chemical dosing in commercial aquatic facilities, water treatment plants, and industrial processing.

Configured with a dedicated 45 RPM gear-motor drive package (145N) paired with the heavy-wall #6T Flex-A-Prene tube assembly, this model bridges the gap between the moderate 30 RPM (130N) and high-speed 60 RPM (114N) platforms. It delivers up to 40.0 to 44.0 GPD (Gallons Per Day) against system discharge backpressures up to 65 PSI (4.5 bar), offering an optimized balance of chemical throughput, pressure handling, and tubing operational life.

Nomenclature & Model Decoding

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

• 145N: Drive package and electrical specification:

  • 1: 115V AC / 60 Hz electrical service (pre-wired with NEMA 5-15 3-prong grounded plug).

  • 45: 45 RPM gear-motor assembly (providing higher delivery than 30 RPM models while extending tube fatigue life relative to 60 RPM units).

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

• -6T: #6T 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 operating over a continuous 60-second time window (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%. Over each 60-second interval, the pump energizes the motor for the selected percentage of the minute and shuts off for the remainder (e.g., at 50%, it runs for 30 seconds and rests for 30 seconds). This avoids batch slug-dosing while maintaining steady chemical concentration in the pool return line.

• Balanced 45 RPM Drive Dynamics: The 45 RPM motor turns the roller carrier at an intermediate velocity. This maintains higher volumetric throughput than 30 RPM units while reducing friction heat and mechanical flex stress compared to 60 RPM drives, yielding longer continuous tubing life.

• Off-Gas & Vapor Lock Immunity: The peristaltic continuous-pinch design forces trapped off-gassing oxygen bubbles ($O_2$ from liquid sodium hypochlorite) and fuming hydrochloric acid vapors ($HCl$) through the discharge tubing without air-binding or loss of prime.

• Self-Priming & Natural Anti-Siphon Barrier: Capable of pulling a vertical suction lift up to 30 feet of water. The planetary rollers maintain positive mechanical compression against the tube track at all times, preventing gravity siphoning into the filtration loop without requiring separate spring-loaded check valves.

• Chemical Containment: Liquid makes contact only with the inner bore of the #6T Flex-A-Prene tube, polyethylene transfer lines, and the injection check valve quill, keeping corrosive chemicals completely separated from internal drive gears and motor bearings.

Technical Specifications

• Max Output Capacity: Up to 40.0 to 44.0 GPD (approx. 1.67 to 1.83 GPH / 105 to 116 mL/min / 151.4 to 166.5 L/day) at 100% continuous runtime.

• Turndown Range: 0.4 to 44.0 GPD (1% to 100% duty cycle via 1-minute repeating timer).

• Maximum Discharge Backpressure: 65 PSI (approx. 4.48 bar).

• Electrical Service: 115V AC, 60 Hz, single phase, approx. 0.40 to 0.50 A operating draw.

• Pump Head Tube: #6T Flex-A-Prene Tube Assembly with quick-disconnect compression ferrules.

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

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

• Ambient Operating 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 #6T Flex-A-Prene tube assembly every 800 to 1,500 run hours under normal commercial pool operating conditions.

• Roller Assembly Lubrication: Clean the planetary roller tracks and apply silicone grease or manufacturer-approved synthetic lube during every tube change to prevent jacket friction and tube scrubbing.

• Injection Fitting Maintenance: Inspect the duckbill check valve quill at the pipe saddle or tap every 3 to 6 months for calcium carbonate scaling, hypochlorite crystallization, or mineral hardening.
