Atos PFE-31022/3DT Pump

Table A005-18/E
Vane pumps type PFE-31, PFE-41, PFE-51 fixed displacement - cartridge design

PFE-*1 are fixed displacement vane pumps, cartridge design with integral hydraulic balancing for high
volumetric efficency, long service life and low noise level.
IN
OUT
They are available in three different body 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.

Pump body Rotor with vanes Balanced plates Shaft
IN port - SAE 3000 flange
OUT port - SAE 3000 flange
Inlet and outlet ports can be oriented in four different positions to match any
installation requirement.

PFE-41
Simplified maintenance as the pumping cartridge can be easily replaced.
Max displacement: up to 150 cm3/rev Max pressure: 210 bar

7 = for second and third position in multiple pumps
Port orientation, see section 6:
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
only for PFE-31 and PFE-41
