Blue-White FlexPro® Metering Pump


The FLEXFLO® M1 Peristaltic Metering Pump provides reliable, smooth chemical feed for low to medium flow municipal water treatment applications. Its self-priming design does not require check valves or seals that can corrode, clog, or leak. The compact size fits easily into tight spaces, while the simple controls and precision adjustment functions make the operation intuitive.

The FLEXFLO M1 metering pump comes with safety features, including built-in leak detection to prevent false triggering and a lockout mechanism to prevent tampering. Communication and interface ports are easily accessed and protected from dust, moisture, and temperature changes. The convenient “no tools required” cartridge loading design enables quick and easy maintenance.
