LMI PUMP MODEL NUMBERING SYSTEM

The Liquid Metronics Model Numbering System uses letters and numbers to specify a particular pump by its two major components:

1)  Drive Assembly
2)  Liquid End

After extending their outputs "up" with the addition of 6.0 and 12.0 Square Inch diaphragms, LMI next introduced their second generation of Liquid Ends. This included more 0.5 SI models, their first family of molded heads, the 100 Series, and the 200 Series of SS LE's.
