FLM series - Electric gear pumps

The electric gear pumps from FLM series are compact units for flow rates up to 24 l/min and operating pressures up to 75 bar. They combine a gear flange pump directly with an electric motor and are available as three-phase or alternating current versions, depending on the application.

*Maximum pressure of the series. The permissible pressure of the selected pump size may be lower; the permissible operating points for flow rate, pressure, and speed can be found in the performance tables in the data sheets.

**Note on viscosity/speed:
4-pole motors (≈ 1450 rpm) up to approx. 350 mm²/s,
6-pole motors (≈ 950 rpm) up to approx. 1,500 mm²/s,
8-pole motors (≈ 700 rpm) up to approx. 2,500 mm²/s.
For higher viscosities, use
Helical gear motors of the G series in use.
