Good Quality A4V Series Hydraulic Axial Variable Displacement Piston Pump A4VSO71LR2D/10R-PPB13N00 For the following operating conditions bearing flushing is required for safe continuous operation: – Applications with special fluids (non-mineral oils), due to limited lubricity and narrow operating temperature range – Operation at critical conditions of temperature and viscosity with mineral oil Flushing is recommended with vertical mounting (drive shaft facing upwards), in order to ensure lubrication of the front bearing and shaft seal. Flushing is carried out via port "U", which is located in the front flange area of the variable displacement pump. The flushing oil flows through the front bearing and leaves the system together with the pump leakage oil at the drain port. |
