The JCB4CX backhoe loader’s hydraulic pump is of the open – center type, equipped with twin gear pumps and hydraulic speed control. It is presumed that the 20/602100 piston pump may also belong to this type of structure, but this needs to be further confirmed.
Flow Capacity
According to different sources, the hydraulic pump flow capacity of the JCB4CX backhoe loader is 81 L/min (21 gpm). Although it is not clear whether the flow capacity of the 20/602100 piston pump is the same, it is likely to be within a similar range.
Relief Valve Pressure
The relief valve pressure of the JCB4CX backhoe loader’s hydraulic pump is 25165.8 KPA (3650 psi), and it is speculated that the 20/602100 piston pump may have the same or similar relief valve pressure settings.
