Hydraulic Axial piston pumps , A4VSO355DR/10R-PPB13N00
Control system HS, HS5, with servo or proportional valve
(for further information, see data sheet 92076)
The stepless displacement control is accomplished by means of a servo or proportional valve and electrical feedback of the swivel angle.
The HS5P control system is equipped with a mounted pressure transducer, which means that it can be used for electric pressure and power control.
Optional:
▶▶ Servo valve (HS);
▶▶ Proportional valve (HS5);
▶▶ Short circuit valve (HSK, HS5K, HS5KP);
▶▶ For the den submerged oil insert (HS5M);
▶▶ With internal control pressure supply (HS5V);
▶▶ Control system with integrated On Board Electronics OBE (HS5E).
Filtration of the hydraulic fluid
Finer filtration improves the cleanliness level of the hydraulic fluid, which increases the service life of the axial piston unit.
A cleanliness level of at least 20/18/15 is to be maintained according to ISO 4406.
At a hydraulic fluid viscosity of less than 10 mm2/s (e.g. due to high temperatures during short-time duty) at the drain port, a cleanliness level of at least 19/17/14 according to ISO 4406 is required.
For example, the viscosity corresponds to 10 mm2/s:
–– HLP 32 a temperature of 73 °C
–– HLP 46 a temperature of 85 °C
