Description
REXROTH Piston Pump Series Specifications
REXROTH piston pumps are renowned for their exceptional reliability, high efficiency, and adaptability to diverse industrial and mobile hydraulic applications. They are categorized into fixed displacement and variable displacement types, each featuring specialized models to meet specific operational requirements.
Fixed Displacement Piston Pumps
A2FO Series
The A2FO series is a bent-axis axial piston pump designed for open-circuit systems. It offers a displacement range of 5 to 1000 cc/rev and belongs to the 6-series product line. Equipped with SAE flanges or threaded working ports, this pump ensures long bearing service life, especially for models with displacements ranging from 250 to 1000 cc/rev. Its robust construction makes it suitable for a wide spectrum of general applications.
A4FO Series
Featuring an axial piston swashplate design, the A4FO series is tailored for open-circuit operations with a displacement range of 16 to 500 cc/rev. It is available in Series 1 (size 1) and Series 3 (sizes 16 to 40, 125 to 500 cc/rev). A notable advantage is its capability to mount additional pumps on the drive through-shaft. For sizes 71 to 500 cc/rev, it can operate with HF oil, though operational parameters will be reduced accordingly.
Variable Displacement Piston Pumps
A4VSO Series
This axial piston swashplate pump is designed for open-circuit systems, with a displacement range of 40 to 1000 cc/rev (Series 1 and 3). It boasts extended bearing life and a comprehensive range of controllers and actuators. The through-shaft structure of the same size enables the formation of combined pumps. For sizes 180 to 355 cc/rev, it can work with HFC fluids while maintaining performance data equivalent to that in mineral oil mode.
A10VSO Series
Available in multiple sub-series, the A10VSO is an axial piston swashplate pump for open-circuit applications:
-
Series 31 & 52: Displacement ranges from 10 to 140 cc/rev (Series 31: 18 to 140 cc/rev; Series 52: 10 cc/rev). It offers a wide selection of controllers, and the through-shaft design (excluding the 10 cc/rev model) allows for combined pump configurations.
-
Series 32: Covering displacements of 71 to 140 cc/rev, this sub-series is characterized by low noise emission, high efficiency, and high reliability. Its universal through-drive design enhances application flexibility.
The A10VSO series operates at a nominal pressure of 280 bar (4000 psi) and a peak pressure of 350 bar (5100 psi). It features two case drain ports, excellent suction performance, and the drive shaft can withstand both axial and radial loads, ensuring a favorable power-to-weight ratio and short control time.
A7VO Series
With a bent-axis axial piston structure, the A7VO series is suitable for open-circuit applications (Series 6) with a displacement range of 28 to 1000 cc/rev. It is robust and versatile, with long bearing service life for sizes 250 to 1000 cc/rev. Optional visual or tilt angle indicators are available for sizes 250 to 1000 cc/rev, facilitating operational monitoring.
Closed-Circuit Variable Pumps
-
A4VSG Series: Displacement 40 to 1000 cc/rev (Series 1 and 3), axial piston swashplate design. Equipped with valve blocks for closed-circuit protection, it can form combined pumps with auxiliary pumps for oil suction boosting and piloting or another axial piston pump of the same size.
-
A4CSG Series: Displacement 250 to 750 cc/rev (Series 3), axial piston swashplate design. Integrated with complete booster pump valve technology, it supports coaxial drive pumps and even combined operation with full auxiliary pumps.
-
A4VB Series: Displacement 450 cc/rev (Series 3), axial piston swashplate variable pump designed for closed-circuit and preload operations.
A2VK & A7VK Series
These pumps adopt a bent-axis axial piston structure, suitable for both open and closed circuits. The A2VK series covers displacements of 12 to 107 cc/rev (Series 1 and 4), while the A7VK series offers a 28 cc/rev model (Series 6). Constructed with improved high-pressure materials for polyurethane component transfer, they feature high displacement accuracy, repeatability, and corrosion resistance via specialized surface treatment. Manual control with precision indicators and clamping devices, combined with dual-shaft seals and flushing chambers made of special materials, ensures easy damage inspection and environmental protection, along with high volumetric efficiency.
All REXROTH piston pump series adhere to strict quality standards, providing stable performance and long service life for demanding applications in construction, marine, agriculture, and industrial machinery.
