德国哈威变量轴向柱塞泵
1) For full stroke hmax and hVol. , 0.95
hmax = 5 mm for type MPE and 7.6 mm for type PE
These versions show a reduced efficiency due to the low viscosity.
Order example: PE 10-HFA
For dimensions, see standard versions
Versions with seal material FKM (Viton)
Type MPE 4...9-PYD, Type PE 6...16-PYD
Order example: MPE 4-PYD
For dimensions, see standard versions
Versions with seal material EPDM (e.g. brake fluid or Skydrol)
2) k = Multiplication factor for number of cylinders and
non-uniformity (sec. 5)
Lh - Service life in h
cdyn. - Dynamic load capacity of the bearing in N
hmechan. - Mechanical efficiency (ca. 0.85)
e - Eccentricity in mm
V - Displacement in cm3
p - Operating pressure in bar
n - Speed in rpm
Versions for low viscosity (e.g. HFA, or conditioned water)
Surface gas nitrided
Type PE 6(7,8,10,12)-HFA
Type MPE 4...9-AT, Type PE 6...16-AT
Order example: PE 12-AT
