The A37, A45, A56, A70, A90, A100, and A145 pumps belong to the category of variable displacement piston pumps.
This means that they can vary the displacement of fluid they deliver, allowing for precise control of hydraulic systems. This feature is particularly beneficial in applications where variable flow rates are required, such as in construction machinery, material handling equipment, and industrial processes.
One of the notable features of these pumps is their high-pressure capability. They are designed to withstand high pressure conditions, typically ranging from 280 bar (4,000 psi) to 350 bar (5,000 psi), depending on the specific model. This makes them suitable for demanding applications that require reliable performance under extreme operating conditions.
Another important characteristic of these pumps is their variable displacement capability. They employ axial piston designs, where the pistons move in an axial direction to generate hydraulic flow. By adjusting the swashplate angle, the displacement of the pistons can be varied, allowing for precise control of fluid delivery. This variable displacement feature enhances energy efficiency, as the pump can deliver the required flow without unnecessary power consumption.
Furthermore, these pumps are equipped with advanced hydraulic control technologies, such as servo-assisted controls or electronic control units (ECUs).
These technologies enable enhanced responsiveness, accuracy, and stability in hydraulic systems. The pumps can be integrated with sophisticated control systems to optimize performance and meet specific operational requirements.
In terms of physical specifications, the A37, A45, A56, A70, A90, A100, and A145 pumps have varying sizes and configurations. Their displacement capacities range from approximately 37 cc/rev to 145 cc/rev, indicating the volume of fluid delivered per revolution. They are available in different mounting options, including flange and foot mounting, to accommodate diverse installation requirements.
These pumps offer exceptional reliability and durability, thanks to their robust construction and high-quality materials. They are designed to withstand harsh operating conditions, including high temperatures, heavy loads, and contamination. This ensures extended service life and reduces maintenance needs, contributing to overall cost-effectiveness.
The A37, A45, A56, A70, A90, A100, and A145 pumps find applications in various industries, including construction, agriculture, mining, marine, and manufacturing. They are commonly used in hydraulic systems for mobile machinery, such as excavators, loaders, cranes, and forklifts. Additionally, they are suitable for stationary applications like hydraulic presses, industrial power units, and material processing equipment.
