1. Axial piston pump with swashplate design for hydraulic drive in
open circuit
2. Visible swing angle indicator
3. Excellent oil absorption characteristics
4. Variable speed drive options
5. Long service life
6. Modular design
7. Short response time
8. The flow rate is proportional to the input transmission speed
and displacement. By adjusting the swashplate angle, the output
flow can be steplessly adjusted.
9. Optional installation location

FAQ:
Q1: DFR1 and DRA can change for each other?
A1: Yes, the installation size is exactly same.
Q2: What is the difference between hydraulic motor and hydraulic pump?
A2: Hydraulic pump is connected with the prime mover, and the pump shaft has no additional radial load;
while hydraulic motor is connected with the load, such as sprockets, pulleys, gears and so on, its main shaft
will bear a higher radial load. 3. The low pressure chamber of the hydraulic pump is usually vacuum
Q3: Where are hydraulic pumps used?
A3: Hydraulic pumps are used on excavators, cranes, loaders, tractors, vacuum trucks, forestry equipment, graders,
dump trucks, mining machinery, etc. Mobile applications use hydraulic pumps more prolifically than do industrial machines,
because electric actuators are generally not used for mobile machinery
