Introduction to the A-100NV


The A-100NV FLEXFLO Peristaltic Metering Pump is a positive displacement chemical metering pump that delivers smooth, continuous chemical feed. It is especially effective when injecting chemicals that off-gas like Peracetic Acid and Sodium Hypochlorite.  The peristaltic technology is a near-continuous flow that delivers consistent precise flow without the need for check valves.  

Flow adjustment on the A100NV Peristaltic Pump is simple and directly related to the motor speed. There are no stroke and spring adjustments needed to achieve precise flow across the entire flow range of the pump. There are no valves that can clog or require maintenance.  

Maintenance of the A-100NV Peristaltic is easy, requiring only simple tube changes. Tube changes only take a few minutes.  

The A-100NV Peristaltic Pump can be supplied with Flex-A-Prene®, Flex-A-Chem®, or Flex-A-Thane® tubing for optimum chemical resistance. 

Product Overview / Features 

  • The A-100NV pump can deliver up to 5.60 GPH (21.2 LPH) at 100% motor speed.  
  • Up to 100 psi. (See specific tube ratings) 
  • DC Motor is capable of 10%/15% -100% turndown, depending on the specific model.   
  • LCD Display and Digital Touchpad. 
  • 4-20mA input speed control. 
  • 0-10 VDC input speed control. 
  • Pulsed frequency input for speed control. 
  • Integral TFD leak detection.  
  • FVS (Flow Verification System) input.  
  • Wetted parts are PVDF connectors and, Flex-A-Prene, Flex-A-Chem, or Flex-A-Thane tubing. 
  • 1 Year Limited Warranty. 


The A-100NV pump is designed to provide smooth chemical feed for a variety of chemicals and processes.  It can reliably pump chemicals that off-gas, such as sodium hypochlorite, peroxide, ammonia, and PAA (peracetic acid), as well as a variety of other chemicals.  

The A-100NV is effective with suction lifts, polymers, slurries, and solutions with minor debris that would normally cause issues with diaphragm pumps. 


Frequently Asked Questions

A-100NV Introduction

  • What’s the difference between the A-100NV and the A-100NVP?

    The A-100NVP is similar to the A-100NV except it is designed and configured to be used specifically with polymers. The A-100NVP uses Flex-A-Thane tubes and includes the TFD+ leak detection system which will sense polymer.

  • What is TFD+?

    TFD+ is an acronym meaning Tube Failure Detection. The plus (+) indicates that the sensor will detect the same chemicals as our standard TFD sensor detects, with the addition of oil based chemicals, like fuels and oil based polymers. The TFD+ is an optical refraction leak sensor that uses an infrared LED and a phototransistor to detect the presence of fluid at the sensor. When fluid is present at the sensor, the refraction of light at the lens changes, which reduces the amplitude of light reaching the phototransistor. Optical leak detectors use infrared photo-refractor principle based on light refraction. These sensors are designed for safety and reliability and have watertight IP67 construction

  • What is TFD?

    TFD is an acronym meaning Tube Failure Detection. Blue-White peristaltic pumps are equipped with a Tube Failure Detection System. The patented system is designed to stop the pump in the event chemical enters the pump head. The system monitors conductivity readings across two sensors located inside the pump head. This system is capable of detecting the presence of a large number of chemicals.

  • What is Sodium Hypochlorite, and why 12½% ?

    Sodium hypochlorite, commonly known in a dilute solution as (chlorine) bleach, is an inorganic chemical compound with the formula NaOCl. Sodium hypochlorite is most often encountered as a pale greenish-yellow dilute solution referred to as liquid bleach, which is a household chemical widely used (since the 18th century) as a disinfectant or a bleaching agent. In solution, the compound is unstable and easily decomposes. Household bleach sold for use in laundering clothes is a 5-1/4 % solution of sodium hypochlorite at the time of manufacture. Strength varies from one formulation to another and gradually decreases with long storage. A 12-1/2 % solution is widely used in waterworks for the chlorination of water, and a 15 % solution is more commonly used for disinfection of waste water in treatment plants.

  • Who is NSF international?
