1, Product Overview
The Rexroth A4VTG90 is a high-performance variable displacement axial piston pump designed for heavy-duty hydraulic systems. As a core product of Bosch Rexroth’s hydraulic power transmission lineup, it integrates advanced engineering, robust construction, and precise control capabilities. It is specifically engineered to convert mechanical energy into hydraulic energy efficiently, providing stable pressure and flow for large-scale machinery and industrial equipment, while adapting to dynamic load changes in complex working conditions.
2, Key Features
.High-Pressure Resistance & Stable Output
The A4VTG90 supports a maximum operating pressure of up to 350 bar (continuous) and 400 bar (peak), enabling it to withstand extreme pressure fluctuations in heavy-duty applications (e.g., construction machinery, mining equipment). Its optimized piston-cylinder assembly and precision-machined housing minimize internal leakage, ensuring consistent flow output even under long-term high-load operation.
.Precise Displacement Control
Equipped with a proportional electro-hydraulic control system, the A4VTG90 allows stepless adjustment of displacement (ranging from 0 to 90 cm³/rev) according to real-time load demands. This precise control enables the pump to match hydraulic output to actual equipment needs, reducing energy waste and improving overall system efficiency by up to 15% compared to fixed-displacement pumps.
.Durable & Low-Maintenance Construction
The A4VTG90 adopts a robust design with key components (e.g., piston, cylinder block, drive shaft) made of high-strength alloy steel and surface-hardened treatment (HRC 58-62). It also features a built-in oil filtration system and wear-resistant seals, extending the service life to over 8,000 operating hours and reducing maintenance frequency by 30% compared to industry averages.
3,Typical Applications
Construction Machinery
Widely used in heavy construction equipment such as hydraulic excavators, wheel loaders, and crawler cranes. It provides the required hydraulic power for key actions (e.g., bucket digging, boom lifting, crane hoisting), ensuring smooth and powerful operation even in harsh construction sites (high dust, vibration, temperature variation).
Industrial Manufacturing
In industrial scenarios, the A4VTG90 is employed in large-scale presses, plastic injection molding machines, and metal rolling equipment. Its precise displacement control ensures consistent pressure for molding processes or material pressing, while its high efficiency helps reduce energy consumption of production lines, aligning with industrial energy-saving requirements.
