FLEXFLO A-100N Peristaltic Metering Pump

Smooth and accurate peristaltic chemical feed that primes itself, even against maximum line pressure, with no valves to clog.

Features & benefits

Key Features & Benefits
Pumping Performance
  • Smooth and accurate peristaltic chemical feed
  • Self-priming, even against maximum line pressure; cannot vapor lock or lose prime
  • No valves that can clog and require maintenance
  • Output volume is not affected by changes in back pressure
  • Output from .01 to 5.2 GPH (.04 to 19.56 LPH), depending on pump tube and motor speed
  • Pressures up to 100 psi (6.9 bar); each pump tube has its own pressure rating
  • Variable speed DC motor with up to 20:1 turndown (model specific)
  • 30 ft. suction lift; viscosities up to 5,000 centipoise; solids up to 50% by volume
Pump Tubes
  • Patented pump tube assembly design
  • Flex-A-Thane, Flex-A-Prene, and Flex-A-Chem tube material options
  • Two pump tube assemblies supplied with each pump: one installed, one spare
Safety & Protection
  • Tube Failure Detection (TFD+)
    • Senses tube failure when chemical enters the pump head and stops the pump
    • Detects a large number of chemicals, including sodium hypochlorite, hydrochloric (muriatic) acid, and sodium hydroxide
  • Flow Verification System (FVS) input for an optional Blue-White flow sensor (sold separately); stops the pump if no flow is detected
Control Options
  • A-100NF: analog dial knob for manual speed control
  • A-100NV: digital control, manual or automatic, accepting 4-20 mA, 0-10 VDC, and pulse input signals
  • Motor active output on both models
Construction
  • Corrosion proof Valox (PBT) housing; NEMA 3R, IP23 enclosure
  • Tamper resistant electronic control panel cover
  • NSF/ANSI 61 certified models available with -4T, -6T, -7T, and -8T tubes
  • 1 Year Warranty
