A1A4-7T 115V/60HZ PERISTALTIC PUMP 100 GPD 40PSI MAX

The Blue-White Industries Flex-Pro / Chem-Pro A1A4-7T (A-100N Series / A100NV Platform) is a heavy-duty, commercial-grade peristaltic chemical metering pump engineered for high-demand aquatic disinfection, municipal water treatment, and industrial fluid processing.

Equipped with a high-torque DC-driven motor, solid-state analog speed control, and a heavy-wall #7T Flex-A-Prene (Santoprene-equivalent) peristaltic tube assembly, this unit delivers up to 100.0 GPD (Gallons Per Day) against operating line backpressures up to 40 PSI (2.8 bar). In commercial aquatic mechanical rooms running Pool Link 500/1000 Series automation controllers, it is commonly specified as a heavy-duty alternative to classic shaded-pole mechanical pumps for bulk sodium hypochlorite (12.5%–15%) and muriatic acid (31.45%) dosing.

Nomenclature & Model Decoding

• A1: Series platform (Blue-White A-100N / Flex-Pro A1 family).

• A: Tube configuration and pump head housing standard.

• 4: Electrical service specification (115V AC / 60 Hz single phase with standard NEMA 5-15 3-prong grounded cord).

• -7T: #7T Heavy-Wall Flex-A-Prene Tube Assembly (optimized for higher chemical feed output up to 100 GPD against 40 PSI).

• 100 GPD: Maximum nominal volumetric delivery rate (~4.17 GPH / ~15.77 LPH).

• 40 PSI MAX: Hydraulic maximum continuous discharge backpressure limit (2.76 bar).

Mechanical Architecture & Operational Dynamics

• Solid-State Electronic Speed Control: Unlike mechanical cam/clutch indexing rings, the A-100N/A1 platform features an electronic potentiometer/rotary dial offering smooth solid-state turndown from 5% to 100% (5 to 100 GPD) with continuous planetary roller rotation rather than intermittent pulsing.

• Chemical Off-Gas Immunity: Designed to eliminate vapor locking and loss of prime when metering off-gassing liquid chlorine ($O_2$) or fuming hydrochloric acid ($HCl$). The advancing roller design compresses and pushes gas pockets through the discharge line without interruption.

• Flex-A-Prene Tube Durability: The proprietary #7T Santoprene-based formulation resists tube fatigue, chemical leaching, and pinhole cracking caused by aggressive chlorine degradation and ozone exposure.

• Positive Displacement Anti-Siphon Protection: The multiple-roller pinch block keeps the tube completely closed at all times, providing a self-priming suction lift up to 30 vertical feet of water and preventing accidental siphon flow into the pool circulation loop without requiring complex external spring check valves.

• Corrosion-Resistant Housing: Housed in a NEMA 3R / IP66-rated chemical-resistant polycarbonate/PBT enclosure designed to withstand corrosive natatorium and chemical room atmospheres.

Technical Specifications

• Max Output Capacity: 100.0 GPD (approx. 4.17 GPH / 263 mL/min / 378.5 L/day) at 40 PSI.

• Output Turndown Range: 5.0 to 100.0 GPD (5% to 100% analog speed dial).

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

• Electrical Service: 115V AC, 60 Hz, 1-Phase, approx. 0.5 to 1.0 A continuous draw.

• Pump Head Tube: #7T Flex-A-Prene Tube assembly with quick-connect compression fittings.

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

• Suction Lift: Up to 30 ft (approx. 9.1 m) vertical water lift.

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

• Duty Cycle: Continuous duty rated; compatible with continuous run, dry-contact pulse, or AC power duty-cycling via Pool Link 500/1000 chemical feed relays.

Routine Maintenance & Consumables

• Tube Replacement Interval: Inspect and replace the #7T Flex-A-Prene tube every 500 to 1,500 run hours (or seasonally every 6 to 12 months depending on operating backpressure and chemical concentration).

• Roller Assembly Care: Clean the roller tracks and lubricate with silicone or manufacturer-approved synthetic lube during each tube replacement to avoid mechanical drag.

• Injection Fitting & Foot Strainer: Inspect the injection check valve quill for mineral encrustation or chlorine crystallization at the main line injection tap every 6 months.

Weight and Logistics Profile

• Net Unit Weight: Approximately 8.0 to 9.5 pounds (approx. 3.63 to 4.31 kg).

• Physical Footprint: Approximately 10.5" L × 6.5" W × 7.0" H (approx. 26.7 cm × 16.5 cm × 17.8 cm).

• Packaged Shipping Dimensions: Heavy-duty parcel carton measuring approximately 14" L × 10" W × 10" H.
