Internal gear pump
PGF Series 2X and 3X
Features:
Low operating noise
Low flow pulsation
High efficiency even at low viscosity due to sealing gap
compensation
Long service life due to slide bearings and sealing gap
compensation
Suitable for a wide viscosity and speed range
Excellent suction characteristics
All frame sizes and sizes can be combined with each other
Can be combined with PGH internal gear pumps, PV7
vane pumps and axial piston pumps
Valve technology can be integrated in the cover on
request
Use:
- For drives in the medium-output and medium-pressure
range in industrial applications, such as machine
tools.
- At high operating pressure for endurant drives in
mobile applications, such as lifting devices, fans and
spreaders.
