f f FLUID POWER DESIGN FEATURES Modern machinery with complex kinematics often calls for multiple movements that are separate and fully independent of each other. In flow equalization and flow division applications and for high pressure actuation, CASAPPA respond with their comprehensive MAGNUM 30 and MAGNUM 35 range of flow dividing gear motors to transmit fluid power using rational technical solutions and at low costs. When these rotary flow dividers are used for the correct applications they permit the optimization of hydraulic circuits and improve pump life, thereby reducing...

W f FLUID POWER DESIGN FLOW EQUALIZERS Flow dividing gear motors are suited for applications where the flow must be divided equally with maximum actuator synchronization difference of ± 2 %. In order to obtain synchronous operation the displacements of the gear sections must be identical. When several single acting cylinders are operated together, acting on loads have not sufficient mass to win the circuit's resistance, we recommend the flow equalizer must be supplemented by a further gear section acting as a motor in order to guarantee the cylinders retract. The displacement of this motor...

W f FLUID POWER DESIGN FLOW DIVIDERS These flow dividers are used where the same pump must drive several different services requiring different pressures and flow rates. The displacement of each section must be proportional to the flow rate required by the service to which it is connected. Two typical circuits in which flow dividers are installed will be found on page 20. Assume two services must be driven absorbing 100 l/min (26.42 US gpm) and 65 l/min (17.17 US gpm) respectively. To find the displacement of the flow divider sections, assuming the HDD 30 group is opted for, simply locate...

W f FLUID POWER DESIGN PRESSURE INTENSIFIERS Pressure intensifies are used for services requiring working pressures in excess of the operating pressure of the pump. Pressure is increased by using one of two sections as a motor connecting it to “tank” and the other as a pump connecting it to the service. For optimum intensification, the ratio R between the displacement of the “motor” and “pump” sections must fall within the range 0.5 ^ 2. The graph on page 11 illustrates pressure intensification available with these units. Two typical circuit diagrams incorporating pressure intensifies are...

W f FLUID POWER DESIGN NOTES ABOUT COMPOSITION Flow divider sections are arranged in descending displacements or groups with the largest displacement to the left as viewed from the delivery ports side. Where flow dividers are made up of different groups, an intermediate inlet section must be disposed between them. Standard formats of flow dividers are given beneath and on the following pages; for different configurations please consult our Technical Sales staff.
