Rexroth hydraulic pump A4VSO180DR/30R-PPB13N00

Rexroth Hydraulic Pump A4VSO180DR/30R-PPB13N00 Product Overview
I. Product Overview
The Rexroth (Bosch Rexroth) A4VSO180DR/30R-PPB13N00 is a swash plate type axial piston variable displacement pump designed for open circuit hydraulic systems. It is widely used in high-power hydraulic transmission applications such as machine tools, metallurgy, forging, mining, and lifting machinery. Its core advantage lies in its stepless displacement achieved by adjusting the swash plate angle. The high-strength cast iron pump body and special alloy key components ensure stable operation under high-pressure and high-load conditions.
II. Core Performance Parameters
Parameter Value Description
Nominal displacement 180 mL/r. Flow rate is proportional to speed and displacement, and can be continuously varied by adjusting the swash plate angle.
Rated pressure 35 MPa (350 bar) meets the pressure requirements of most industrial hydraulic systems.
Peak pressure 42 MPa (420 bar) allows for short-term operation at higher pressures to accommodate sudden loads. Speed ​​Range: Up to 3300 r/min, adapting to high-speed drive requirements and improving system response speed.
Volumetric Efficiency: ≥90% reduces hydraulic oil leakage and improves energy utilization.
Total Efficiency: ≥95% provides efficient transmission and reduces energy consumption.
Noise Level: ≤85 dB(A): Low-noise design improves the working environment.
Suction Pressure: Minimum -0.8 bar (absolute) provides excellent oil suction characteristics and prevents cavitation.
Media Temperature: -20°C to +80°C, adapting to a wide operating temperature range.
Drive Shaft Load: Withstands axial and radial loads. The robust drive shaft design adapts to complex operating conditions.
III. Structure and Design Highlights
Swash Plate Variable Flow Structure
Adjusting the swash plate angle to change the plunger stroke enables stepless flow adjustment, resulting in fast response time and high control accuracy.
A hydrostatic unloading design is used between the swash plate and the cylinder block to reduce friction and extend service life. Modular Design
Supports through-drive, allowing pumps of the same nominal size to be installed in parallel to expand system flow.
A variety of modules, including pressure controllers, flow controllers, and power controllers, are available to meet diverse control needs.
High-Strength Materials
The pump body is constructed of cast iron for high pressure resistance; key components such as the plunger and swash plate are constructed of a special alloy for excellent wear resistance.
Machining precision reaches micrometers, ensuring precise clearance between the plunger and cylinder, minimizing leakage.
Sealing and Filtration
A 25μm oil filter is standard at the outlet to prevent impurities from entering the system.
Seal components are made of high-performance materials to ensure long-term leak-free operation.
