Series F – Gear-driven flange pumps

The gear flange pumps from F series are external gear pumps with free shaft ends for operating pressures up to 100 bar.
The series can be adapted to the medium, viscosity, and temperature range via shaft seals, bearings, and optional valves.

Properties

Funding volume: 0,43 – 86,8 cm ³/U
(corresponds to approx. 0.6 - 124 l/min at 1450 rpm)
Viscosity**: 1,4 / 20.000 mm²/s
Maximum pressure*: up to 100 bar
Typical motor power range: 0,12 / 18,5 kW
Media temperature: -40 to +200 °C (depending on seal material and material pairing)

*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
Spur gear motors.
