Overview

FL Series – Liquid Ring Pumps are the only safe option for pumping hydrocarbons and other flammable or hazardous materials due to the impeller operating in an intermediate fluid. These pumps also offer high airflow with very low noise levels.

Application Performance

The FL2 liquid ring vacuum pump performs best with 2” hoses.
The truck friendly design makes the pump very easy to install on any type of chassis.
