A20VLO Pump

The A20VLO pump is a Rexroth swash plate construction double axial piston rotary assembly variable displacement pump, mainly used for hydrostatic transmissions in open circuits, suitable for traveling machines and stationary applications. The following is a detailed description of the A20VLO pump:

First, Product Features

1.Swash plate structure: the adoption of swash plate structure double axial piston rotary assembly, compact design, high efficiency.

2. variable control: the displacement of the pump can be infinitely variable between the maximum and minimum displacement to meet the needs of different working conditions.

3. Multiple control modes:

LR: Power control.

DR: Pressure control.

HD: Pilot pressure control.

EP: Electrical control with proportional solenoid.

4. Self-priming ability: self-priming, pressurized tank or with a booster pump, adapting to different working environments.

5. Constant power control: Settings can be externally adjusted, even when the unit is in operation (with power control).

6. through-axis drive: suitable for installation of gear pumps or a second axial piston pump, increasing system flexibility.

Second, technical parameters

1.Specifications: provide a variety of specifications, such as 190, 260, 520, etc., to meet different flow requirements.

2. Working pressure:

Rated pressure: 35MPa (350bar).

Peak pressure: 45MPa (450bar).

3. Speed range:

Self-priming upper speed: according to different specifications, the self-priming upper speed is between 1600r/min and 2650r/min.

Peak speed: depending on the specifications, the peak speed is between 2000r/min and 3250r/min.

Third, Application Scenarios

1. Engineering machinery: excavator, loader, etc.

2. Industrial machinery: injection molding machine, die-casting machine, etc.

3. Marine field: rudder, deck machinery, etc.

Fourth, maintenance and repair suggestions

1.Oil management: Regularly check the cleanliness of oil and replace the oil and filter element in time.

2. Tightening torque check: For DIN 13 fixing screws, it is recommended to check their tightening torque individually according to the 2003 version of VDI 2230.

3. Safety precautions: During and shortly after operation, there may be a risk of burns caused by the pump (especially the solenoid) and appropriate safety precautions, such as a protective clothing program, should be taken.
