FlexFlo A-100NA 130N 115V -7T 1 MIN

The Blue-White Industries FlexFlo A-100NA (Model A-100NA-130N / A-100N Series) with -7T 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 automation, municipal water treatment, and industrial fluid applications.

By pairing a durable 30 RPM gear-motor drive package (130N) with the high-output #7T Flex-A-Prene tube assembly, this model delivers a maximum volumetric output of 48.0 to 50.0 GPD (Gallons Per Day) against system line backpressures up to 30 to 40 PSI (2.1 to 2.8 bar). The 30 RPM operating speed reduces continuous mechanical stress and linear roller friction on the tube, while the internal solid-state 60-second repeating duty-cycle timer provides controlled chemical dispersion when integrated with Pool Link 500/1000 Series controllers.

Nomenclature & Model Decoding

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

• 130N: Drive package and electrical specification:

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

  • 30: 30 RPM gear-motor assembly (delivering extended tube wear life and moderate delivery rates relative to 60 RPM 114N models).

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

• -7T: #7T Flex-A-Prene (Santoprene-grade) heavy-wall, large-bore 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 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.

• Optimized 30 RPM Drive Kinetics: Running at 30 RPM rather than 60 RPM halves the frequency of roller compressions over time. This decreases internal tube friction and operational heat buildup, extending the operational life of the large-bore #7T tube in heavy commercial pool environments.

• Off-Gas & Vapor Lock Immunity: The continuous-pinch peristaltic design pushes off-gassing oxygen bubbles ($O_2$ from liquid chlorine) and fuming hydrochloric acid vapors ($HCl$) directly through the discharge line, completely bypassing the gas-binding vulnerabilities of diaphragm pumps.

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

• Chemical Isolation: Fluid contacts only the inner bore of the #7T Flex-A-Prene tube, polyethylene suction/discharge piping, and the injection check valve quill, keeping motor windings and drive gears completely isolated from corrosive liquids and fumes.

Technical Specifications

• Max Output Capacity: Up to 48.0 – 50.0 GPD (approx. 2.00 – 2.08 GPH / 126 – 131 mL/min / 181.7 – 189.3 L/day) at 100% continuous runtime.

• Turndown Range: 0.5 to 50.0 GPD (1% to 100% duty cycle via 1-minute repeating timer).

• Maximum Discharge Backpressure: 30 to 40 PSI (approx. 2.07 to 2.76 bar).

• Electrical Service: 115V AC, 60 Hz, 1-Phase, approx. 0.35 to 0.5 A 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: Continuous or intermittent duty-cycle rated; fully compatible with external powered relays or dry-contact outputs from Pool Link 500/1000 Series chemical 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 1,000 to 2,000 run hours (significantly longer interval than 60 RPM units due to reduced roller passes).

• 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.
