Product Description
The A4VG pump features a swash plate design that allows for variable displacement to meet the specific flow and pressure requirements of the hydraulic system. This makes them suitable for a wide range of applications, including construction machinery, agricultural equipment and material handling systems.
These pumps are available in various sizes and configurations to meet different system requirements. They are designed to provide smooth and reliable operation even under demanding conditions and provide a long service life with minimal maintenance.
Product Feature
● Variable axial piston pump of swash plate design for hydrostatic closed circuit transmissions
● Flow is proportional to drive speed and displacement and is infinitely variable
● Output flow increases with the swivel angle of the swash plate from 0 to its maximum value
● Flow direction changes smoothly when the swash plate is moved through the neutral position
● A wide range of highly adaptable control devices is available for different control and regulating functions
● The pump is equipped with two pressure-relief valves on the high pressure ports to protect the hydrostatic transmission (pump and motor) from overload
● The high-pressure relief valves also function as boost valves
● The integrated boost pump acts as a feed and control oil pump
● The maximum boost pressure is limited by a built-in boost pressure relief valve
● The integral pressure cut-off is standard
Product Application
High-pressure, high-flow, and high-power systems make considerable use of piston pumps, especially in situations where accurate flow control is crucial. Hydraulic presses are widely used in machine tools, heavy-duty planers, mobile and construction equipment, engineering vehicles, hydraulic presses, oilfield equipment, mining and metallurgical machinery, and maritime and other hydraulic systems.
