FL3400

 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 FL3400 liquid ring vacuum pump performs best with 6” hoses.
4” and 5” hoses can be used with a reduced RPM, and hoses larger than 6” can be used, but this is recommended for fluid lifts only. The truck-friendly design makes this pump very easy to install on any chassis.
