Rexroth Axial Piston Variable Pump A7vo 28/55/80/107/160 for heavy machine
Detail Model Number(The following models are for reference only, please contact us for more details)
Axial Piston Variable Pump A7vo 28/55/80/107/160 with Excellent Performances
 The A7VO is variable displacement piston pump, extremely high power density, and extraordinary reliability. It is the core power source for heavy machinery and industrial hydraulic systems worldwide. 
1, Overview of A7VO Pump Core Products
The Rexroth A7VO series is a slanted disc, axial variable displacement piston pump. Its main function is to convert the mechanical energy of the prime mover (such as a diesel engine or motor) into hydraulic energy (pressure and flow rate of high-pressure oil), and through its variable mechanism, intelligently adjust the output flow rate according to system requirements, thereby achieving system energy saving and precise control.
2, Working principle and technical characteristics
working principle
The operation of A7VO pump is based on the principle of inclined disc axial piston. The drive shaft drives the cylinder body to rotate, and the plunger moves back and forth inside the cylinder body. The inclination angle of the inclined plate determines the stroke length of the plunger, which in turn determines the displacement of the pump. By changing the angle of the inclined plate, the output flow can be infinitely adjusted between zero and maximum displacement.
Core product features and advantages
· Ultra high performance: Equipped with optimized bearings and friction pairs, it can withstand extremely high continuous working pressures (up to 400 bar or more) and has a high power density.
· Efficient and energy-saving: Advanced variable control technology (such as constant power control) can ensure that the output of the pump perfectly matches the system requirements, avoiding energy waste and significantly reducing fuel or electricity consumption.
· Excellent reliability: Robust structural design, forced circulation lubriion, and high-quality manufacturing processes ensure long-lasting operation even under the most demanding working conditions.
· Low noise level: Optimized manifold design and pre compression technology effectively reduce pressure shock and operating noise, meeting strict environmental requirements.
· Highly modular: Provides multiple control modes, displacement specifiions, installation flange and shaft extension options, supports highly customized, and meets the integration needs of different host devices.
3, Main variable control method
The A7VO pump provides multiple control modes to adapt to various complex system requirements, which is the core manifestation of its powerful functions:
· Constant power control (LR, LU, etc.): the most classic and common control method. The pump automatically adjusts the displacement to maintain a constant output power (pressure x flow rate), effectively protecting the prime mover (diesel engine or motor) from overload, making it an ideal choice for construction machinery.
· Hydraulic remote control (HD): The displacement of the pump is remotely adjusted through external hydraulic signals.
· Electro hydraulic proportional control (ED, EW): By receiving electrical signals (such as 0-10V or 4-20mA) through proportional electromagnets to control displacement, it is easy to integrate into PLC or intelligent control systems to achieve precise automation control.
· Pressure cutoff control (DR): When the system pressure reaches the set value, the pump displacement automatically decreases to only maintain the level of leakage compensation, achieving energy saving.
· Load sensitive control (LV): Automatically providing the required flow and pressure based on load demand is a key component of efficient and energy-saving systems.
4, Typical appliion areas
The A7VO variable displacement pump is widely used in:
· Construction machinery: hydraulic excavator, concrete pump truck, rotary drilling rig, truck crane, paver.
· Mining machinery: underground loader (LHD), mining drilling rig, mining dump truck.
· Marine engineering: deck machinery (winches, anchors), servos, ship cranes.
· Industrial appliions: plastic injection molding machines, presses, metallurgical equipment, test benches.
· Forestry machinery: wood harvesters, logging machines.
5, How to select a model for your system? 
Choosing the appropriate A7VO model is key to ensuring system performance. Please consider the following parameters comprehensively:
1. System working pressure: Determine the maximum continuous working pressure and peak pressure.
2. Flow demand: Calculate the maximum and minimum flow rates (L/min) required by the system to determine the required pump displacement (ml/rev).
3. Control way: Select according to the host function and control strategy (for example, excavators usually use constant power LR control+pressure cutoff DR).
4. Drive source: Match the speed, power, and torque characteristics of the prime mover.
5. Installation interface: Confirm the installation flange standard (such as SAE C, DIN, ISO) and shaft extension form (such as with internal splines or flat keys).
6. Additional functions: Do you need to integrate booster pumps, auxiliary pumps, etc.

6, Frequently Asked Questions (FAQ)
· Q: What are the main differences between A7VO pump and A10VO/A11VO pump?
· A: A7VO is a variable displacement pump in the medium to heavy-duty series, characterized by its constant power control and high power density, commonly used in mobile machinery. A10VO/A11VO are more inclined towards industrial appliions, with different design focuses and pressure and displacement ranges.
· Q: Where can I download the official samples and technical materials of A7VO?
· A: Contact us and we will quickly provide you with a complete PDF sample manual.
