Introduction to the M3 (Legacy)

Description 

The M3 (Legacy) 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.  

Note: The M3 (Legacy) pump has a newer version. If you have questions about the new M3S FLEXFLO pump, click here.
