Vane pumps type PFE-31, PFE-41, PFE-51
fixed displacement - cartridge design

ቨ

PFE-*1 are fixed displacement-twelvevane pumps, ባ ቤ cartridge design
with integral hydraulic balancing ብ for
high pressure operation, long service
life and low noise level.

ቧ
IN

OUT

They are available in three different
sizes with max displacements up to 44,
85 and 150 cm3/rev and single, multiple
or with through-shaft configurations.
Mounting flange according to SAE
J744 standard.

Fixed displacement vane pump

Additional suffix for multiple pumps:
X2 = double pump composed of single vane pumps
X3 = triple pump composed of single vane pumps

Series number

Eventual suffix for pumps with through shaft:
XA = for coupling one PFE-31
XB = for coupling one PFE-41 (only for PFE-41 and PFE-51)
XC = for coupling one PFE-51 (only for PFE-51)
XO = with through shaft, without rear flange
Note:mulitple pumps are assembled in decreasing order of
size. See also tab. A190.

Port orientation, see section ‫:ݛ‬
T = standard
U, V, W = on request
Direction of rotation (viewed from the shaft end):
D = clockwise (supplied standard if not otherwise specified)
S = counterclockwise
Note: PFE are not reversible
