Double vane pumps type PFED
fixed displacement

ᕈ

ᕇ

OUT

PFED are fixed displacement double
vane pumps ባቤ composed by two cartridges of pumps type PFE (see tab.
A005) assembled in a main body having
one inlet port ቦ and two outlet ports ቧቨ.

ᕉ
OUT

IN

PFED-43 are composed by one cartridge
of PFE-41 and one cartridge of PFE-31.
PFED-54 are composed by one cartridge
of PFE-51 and one cartridge of PFE-41.
Suitable for hydraulic oils according to
DIN 51524...535 or synthetic fluids having
similar lubricating characteristics.
These pumps can be assembled, as
second element, with PFE-4 and PFE-5 to
obtain triple pumps, see tab A190.

from -20°C to +70°C

Fluid

Hydraulic oil as per DIN 51524...535; for other fluids see section ‫ݗ‬

Recommended viscosity
max at cold start
max at full power
during operation
min at full power
Fluid contamination class

800 mm2/s
100 mm2/s
24 mm2/s
10 mm2/s
ISO 4401 class 21/19/16 NAS 1638 class 10 (filters at 25 µm value with ß25 ≥ 75 recommended)

Fluid temperature

-20°C +60°C

Recommended suction line pressure

from -0,5 to 1,5 bar for speed up to 1800 rpm; from 0 to +1,5 bar for speed over 1800 rpm

-20°C +50°C (water glycol)

-20°C +80°C (/PE seals)
