Product Description
A7VO 55/107/160 Series Industrial Piston Pumps
The A7VO series represents high-performance variable displacement piston pumps engineered for demanding construction machinery and industrial hydraulic systems. These pumps deliver exceptional power density, reliability, and energy efficiency for heavy-duty applications worldwide.
Technical Overview
The Rexroth A7VO 55/107/160 series features slanted disc, axial variable displacement piston pump technology. These units convert mechanical energy from prime movers (diesel engines or motors) into hydraulic energy, with intelligent flow adjustment capabilities that optimize system performance and reduce energy consumption.
Core Features & Advantages
- Ultra-high performance: Withstands continuous working pressures up to 400 bar with optimized bearings and friction pairs
- Energy efficient: Advanced variable control technology matches output to system requirements, reducing fuel and electricity consumption
- Exceptional reliability: Robust structural design with forced circulation lubrication for demanding conditions
- Low noise operation: Optimized manifold design and pre-compression technology minimize pressure shock
- Modular design: Multiple control modes, displacement specifications, and installation options for custom integration
Control Methods
The A7VO piston pump offers versatile control options to meet complex system requirements:
- Constant power control (LR, LU): Maintains constant output power, ideal for construction machinery
- Hydraulic remote control (HD): External hydraulic signal adjustment
- Electro-hydraulic proportional control (ED, EW): Electrical signal integration for PLC and automation systems
- Pressure cutoff control (DR): Reduces displacement at set pressure for energy conservation
- Load sensitive control (LV): Automatically provides required flow and pressure based on demand
Application Areas
These variable displacement pumps serve multiple industries including construction machinery (excavators, concrete pump trucks, cranes), mining equipment, marine engineering, industrial machinery, and forestry equipment.
