1.      Fixed displacement vane pump

2.      Additional suffix for multiple pumps:

X2 = double pump composed of single vane pumps

X3 = triple pump composed of single vane pumps

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.

3.      Size, see section    :

31, 41, 51

4.      Displacement [cm3/rev], see section  

for PFE 31: 016, 022, 028, 036, 044

for PFE 41: 029, 037, 045, 056, 070, 085

for PFE 51: 090, 110, 129, 150

5.Only for multiple pumps PFEX*: type of second (and third) pump

6. Drive shaft, see section and cylindrical, keyed for single and multiple pump (only first position)

1 = standard

2 = long version (only for PFE-41 and PFE-51)

3 = for high torque applications splined

5 = for single and multiple pumps (any position)

6 = for single and multiple pumps (only first position) (only for PFE-31 and PFE-41)

7 = for second and third position in multiple pumps (only for PFE-31 and PFE-41)

7.     Direction of rotation (viewed from the shaft end):

D = clockwise (supplied standard if not otherwise specified)

S = counterclockwise

Note: PFE are not reversible

8. Port orientation, see section    :

T = standard

U, V, W = on request

9. Design number

10.  Synthetic fluids:

WG = water-glycol

PE   = phopsphate ester
