WebModern hydraulic pumps (axial-piston, radial, vane, etc) are designed with internal leakage passages for cooling. Somewhere between 2-6% of total flow is "leaked" or intentionally siphoned away from the flow outlet for cooling of the pump's sliding surfaces. The flow rate through these passages is obviously dependent on viscosity. WebThe ViO26-6 is equipped with a “Flow Sharing” hydraulic system comprising a variable-flow piston pump (with maximum flow rate of 75 l/min) and a load signalling and flow sharing distributor. Each section of the distributor has a pressure balance that delivers flow proportional to the operator's demand and the available instantaneous flow ...
