12/72 Hagglunds CA | Radial piston hydraulic motor 4.4 Recommended charge pressure The hydraulic system must be such that the motor will recieve sufficient charge pressure at the low pressure port. This applies to all types of installations. 4.4.1 The motor working in driving mode only For CBm 2000 - CBm 6000. The pressure at the Low pressure port, should, during operation of the motor, be at least one bar above the case pressure independent of numbers of ports that are connected. Two cases to be considered: Case 1: No shock loads. Required charge pressure = case pressure + 1 bar during...
