A3

Introduction to the A3

Description 

The FLEXFLO® A3 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 A3 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.  

Maintenance of the A3 Peristaltic is easy, requiring only simple tube changes. Tube changes only take a few minutes.

Applications 

The A3 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 A3 is effective with suction lifts, polymers, slurries, and solutions with minor debris that would normally cause issues with diaphragm pumps. 

Ordering Information and Product Matrix 

image 1

Pumps must be ordered with a complete part number, specifying power cord, tube fitting connection, tube type, and pump head orientation (default pump head orientation is left-facing.) A sample complete part number is A3SV24-MNGG-R, indicating 115V/60Hz NEMA 5/15 plug style power cord, ½” Male NPT fittings, NGG tube, and Right facing pump head.
