Product Description
A2FO A2FE A2FM Piston Hydraulic Pump A2FO 10 12 16 23 32 45 56 107 160 200 250 Axial Piston Fixed Pump A2FO28/61R-VBB05
Displacement: 28cm³/rev.
Pressure: The rated pressure can reach 400bar, and the peak pressure can reach 450bar.
Rotational speed: The specific maximum rotational speed varies depending on the model and working conditions. Generally, the rotational speed range is around 500 to 2500rpm.
Flow rate: The flow rate is directly proportional to the driving speed and displacement. When the driving speed is 1500rpm, the flow rate is approximately 42L/min (28×1500÷1000).2. Working Principle:
The A2FO28/61R-VBB05 is an axial piston pump, featuring an oil distribution plate for oil distribution and a rotating cylinder body. When the cylinder rotates, the plunger moves back and forth in the plunger chamber. Through the oil suction and discharge Windows of the oil distribution plate, the hydraulic oil is sucked in and discharged. Due to the adoption of a hydrostatic balance structure between the sliding shoe and the variable head, as well as between the oil distribution plate and the cylinder body, friction and wear are reduced.
3. Product Features and Advantages:
Compact structure: It adopts an axial plunger structure, which is small in size, has a high power-to-weight ratio, and is convenient for installation in equipment with limited space.
Excellent high-pressure performance: With a high rated pressure, it can operate stably in high-pressure environments, meeting the demands of hydraulic systems with strict pressure requirements.
High efficiency: The volumetric efficiency can usually reach over 90%, and the mechanical efficiency also remains at a good level, which can effectively reduce energy loss and achieve efficient and energy-saving operation.
Strong anti-pollution ability: The design takes into account the tolerance to hydraulic oil contamination, using wear-resistant and corrosion-resistant materials and precise manufacturing processes to reduce the failure rate caused by oil contamination.
Multiple installation forms: We offer a variety of installation methods, such as flange installation and shaft extension installation, to facilitate users’ selection based on the actual system layout.
4. Function and application:
As a power component of the hydraulic system, it converts mechanical energy into hydraulic energy, providing stable pressure oil for the hydraulic system to drive the operation of hydraulic actuating components such as hydraulic cylinders and hydraulic motors. It is mainly used in situations that require high-pressure and efficient hydraulic power.
5. Applicable machines and scenarios:
Widely used in construction machinery, such as excavators, loaders, bulldozers, cranes, etc. It is also applicable to the hydraulic systems of industrial equipment such as mining machinery, metallurgical machinery, forging and pressing machinery, and machine tools.

7. Precautions for Use
Installation: The pump and motor shafts must be aligned, with a coaxiality of no more than 0.01mm. Flexible couplings should be used as much as possible. The suction pipe should be as short, straight, large and thick as possible. Generally, a coarse filter with a nominal flow rate of no less than twice the pump flow rate should be installed on the suction pipe pipeline. Both the suction pipe opening and the return pipe opening should be 200mm below the oil surface.
In terms of working oil: L-HM32, 46, and 68 grades of low pour point high-pressure anti-wear hydraulic oil should be used. Select the appropriate grade based on temperature changes. The working oil temperature should be 15-65℃, with an ideal working oil temperature of 50±4℃.
In terms of operating parameters: Avoid long-term operation at the highest pressure and highest speed, otherwise it will affect the service life of the pump.
