ATOS PFE PFED series hydraulic vane pump PFE-42045/42056/42070/52090/52110/52129/1D/1S/2D/2S/3D/3S/5D/5S PFE-31022/1DU

Double vane pumps type PFED fixed displacement 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. 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. Mounting according to SAE J744. Easy installation as inlet and outlet ports can be assembled in any of four relative positions. Easy maintenance as pumping cartridge can be replaced in a few minutes. Hydraulic symbol body first cartridge: stator, rotor, vanes, balanced plates second cartridge: as above shaft inlet port first outlet port PFED-43 second outlet port Wide variety of displacements: from 29+16 up to 150+85 cm3/rev. Max pressure up to 210 bar. MODEL CODE /* Seals material: omit for NBR (mineral oil & water glycol) PE = FPM Fixed displacement double vane pump Series number Size of cartridges: 43 = composed by: one cartridge of PFE-41 + one cartridge of PFE-31 Ports orientation, see section ‫ݚ‬ Direction of rotation (as viewed at the shaft end): D = clockwise (supplied standard if not otherwise specified) S = counterclockwise 54 = composed by: one cartridge of PFE-51 + one cartridge of PFE-41 Note: PFED are not reversible Drive shaft, see section ‫ ݜ‬and ‫:ݝ‬ Displacement of first element [cm3/rev], see section ‫ݙ‬ cylindrical, keyed 1 = supplied standard if not otherwise specified 2 = according to ISO/DIN 3019 3 = for high torque applications Displacement of second element [cm3/rev], see section ‫ݙ‬ splined 5 = for PFED-43: according to SAE B 13T 16/32 DP (13 teeth) for PFED-54: according to SAE C 14T 12/24 DP (14 teeth) 6 = (only for PFED-43) = according to SAE C 14T 12/24 DP (14 teeth) 7 = (only for PFED-43) = similar to shaft type 6. It is used when PFED-43 is the last element of a multiple pump MAIN CHARACTERISTICS OF DOUBLE VANE PUMPS TYPE PFED Installation position Axial and radial loads are not allowed on the shaft. The coupling should be sized to absorb the peak horsepower developed. Ambient temperature 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 Fluid temperature 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
