Introduction to the M3

Description

The FLEXFLO® M3S 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 M3S 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 M3S Peristaltic is easy, requiring only simple tube changes. Tube changes only take a few minutes.  

The M3S Peristaltic Pump can be supplied with Flex-A-Prene®, Flex-A-Chem®, or Flex-A-Thane® tubing for optimum chemical resistance.

Applications 

The M3S 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 M3S 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
