Description
Key Features of a Variable Displacement Piston Pump:
- The A11VO is a variable displacement pump of axial piston swashplate design for use in open circuit hydrostatic drives.
- Designed principally for use in mobile applications.
- The pump operates under self-priming condition, with tank pressurisation or with charge pump (impeller).
- A wide variety of controls are available.
- Setting of the constant power control is possible via external adjustments, even when the unit is operating.
- The pump is available with a through drive to accept a gear pump or a second axial piston pump up to the same size
(100 % through drive). - SAE mounting flange.
- Output flow is proportional to drive speed and pump displacement and is steplessly variable between maximum and zero.
FAQ’s
Q: 1. How do variable displacement pumps work?
A11VLO Variable displacement pumps can vary fluid output by altering the angle of swashplate or stroke length of pistons. This enables flow rate and pressure to be controlled when necessary.
Q: 2. What is the principle of displacement pump?
Displacement pumps transfer a definite amount of fluid by trapping and pushing it through the system. They are suitable in high pressure and precision applications.
Q: 3. What is a variable displacement pump?
A variable displacement pump is able to vary its output flow without variation of the pump speed. It provides flexibility and energy efficiency on hydraulic systems.
Q: 4. How to adjust a variable displacement pump?
A variable displacement pump can be adjusted with a control system such as a pressure compensator or manual lever. This controls the swashplate angle to vary output.
Q: 5. Can axial piston pumps be variable displacement?
Axial piston pumps are variable displacement Yes, by changing the angle of the swashplate. This enables accurate delivery of fluid according to the demand.
Q: 6. What are the benefits of axial piston pump?
A11VO – Axial piston pump is highly efficient, compact, and capable of withstanding a high pressure. They fit challenging industrial and mobile applications.
Q: 7. What is the difference between piston pump and axial piston pump?
The general type is called a piston pump and an axial piston pump has the pistons aligned in the same direction as the drive shaft. Axial ones are smaller and more efficient.
Q: 8. Is an axial piston pump fixed displacement?
Axial piston pumps can be of fixed and variable displacement. Fixed models provide fixed flow whereas variable models permit variable flow.
