FlexFlo A-100NA 160N 115V -6T 1 MIN

The Blue-White Industries FlexFlo A-100NA (Model A1N30A-6T) is a commercial-grade, medium-capacity peristaltic chemical metering pump engineered for precise chemical dosing in commercial aquatic automation, water treatment, and municipal disinfection systems.

Configured with a 30.1 GPD nominal output and rated for system line backpressures up to 75 to 100 PSI (5.2 to 6.9 bar), the A1N30A-6T features Blue-White's patented Tube Failure Detection (TFD) system, an integrated analog 60-second repeating cycle timer, and heavy-wall #6T Flex-A-Prene tubing. Paired with Pool Link 500/1000 Series automation controllers, it is standard equipment for controlled, high-pressure injection of sodium hypochlorite (12.5% to 15%) and muriatic acid (31.45%).

Nomenclature & Smart-Part Breakdown

• A1: Series platform (FlexFlo A-100N / A-100NA platform).

• N: Standard analog electronic control package.

• 30: Maximum motor drive gear assembly speed configuration (60 RPM nominal output base rating).

• A: 115V AC / 60 Hz electrical power supply (includes standard NEMA 5-15 3-prong grounded plug).

• -6T: #6T Flex-A-Prene (Santoprene-grade) heavy-wall peristaltic pump tube assembly with 3/8" OD compression connection fittings.

Mechanical Architecture & Advanced Features

• Patented Tube Failure Detection (TFD): Built-in optical/conductive sensors in the bottom of the pump head detect the presence of chemical in the event of an internal tube rupture. The TFD circuit immediately shuts off the motor drive and triggers an open-collector alarm output, preventing corrosive chemicals from leaking into the mechanical room or damaging internal pump components.

• Solid-State 60-Second Cycle Timer: Equipped with an analog potentiometer control dial providing up to a 20:1 turndown ratio (5% to 100% capacity). The internal timer cycles the pump motor between 3 seconds and 60 seconds of on-time per 60-second interval, ensuring controlled chemical dispersion without line pulsing or batch slug-feeding.

• High-Pressure Capability: Built with heavy-duty roller bearings and a reinforced pump track calibrated to maintain complete tube occlusion against backpressures up to 75 to 100 PSI, preventing pressurized recirculating water from back-feeding into the chemical reservoir.

• De-Gassing & Off-Gas Immunity: The continuous peristaltic roller compression naturally evacuates off-gassing oxygen ($O_2$ from liquid chlorine) and fuming hydrochloric acid vapors ($HCl$) through the discharge tubing without air-binding, loss of prime, or vapor lock.

• Self-Priming & Natural Anti-Siphon Barrier: Self-primes against system pressure with a suction lift up to 30 vertical feet of water. The dual-roller assembly maintains positive mechanical pinch-closure on the tube track at all times, preventing gravity siphoning without requiring external spring-loaded check valves.

• Rugged Housing: Constructed from chemical-resistant Valox (PBT) thermoplastic with a separate sealed electronics compartment (NEMA 3R / IP23 weather-resistant rated for indoor or sheltered outdoor installations).

Technical Specifications

• Output Turndown Range: 1.5 to 30.1 GPD (5% to 100% duty cycle via 60-second repeating timer).

• Maximum Discharge Backpressure: 75 to 100 PSI (approx. 5.17 to 6.89 bar).

• Electrical Service: 115V AC, 60 Hz, 1-Phase, 1.87 A max operating current.

• Motor Speed: 60 RPM maximum output.

• Pump Head Tube: #6T Flex-A-Prene Tube Assembly (Part No. A-002N-6T / A1-6T) with compression nuts.

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

• Maximum Viscosity: 5,000 Centipoise.

• Operating Ambient Limits: 14°F to 110°F (-10°C to 43°C); process liquid temperature up to 130°F (54°C).

Maintenance & Consumables

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

• Tube Failure Detection (TFD) Sensor Care: Clean the two stainless steel sensor contact pins located in the lower pump head basin with isopropyl alcohol whenever a tube change is performed to ensure residue-free detection.

• Roller Assembly Lubrication: Clean roller paths and apply silicone grease or manufacturer-approved synthetic lubricant during every tube change to prevent outer tube friction wear.

• 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.
