Bosch Rexroth Radial Piston Pumps
Extreme performance for high-pressure applications and multiple flow rates
Fluid System is the official distributor of Bosch Rexroth radial piston pumps, ultra-high-performance hydraulic pumps (radial piston hydraulic pumps) for critical applications requiring extremely high pressures, operational continuity and the availability of multiple independent flow rates from a single hydraulic unit. Thanks to their radial piston design, they ensure maximum volumetric efficiency, consistent performance under load and long service life even under demanding conditions.
The high precision in pressure generation, reliability in continuous cycles and the ability to supply different circuits from a single pump make them well suited to complex systems, high-power installations and dynamic industrial processes. Designed to operate at pressures up to 700 bar, they offer benchmark performance in the sector and ensure maximum stability and control in the most demanding processes.
TECHNICAL FEATURES
Extremely high operating pressure, up to 700 bar.
Multiple independent flow rates at the connections, allowing different functions to be performed simultaneously within a hydraulic system.
Wide range of configurations available, with a variable number of pistons from 3 to 10 to suit specific requirements.
Nominal flow rates in the 3-piston versions from 0.40 to 2.00 cm³/rev, and in the 3/5/10-piston versions from 1.60 to 20.00 cm³/rev.
High volumetric efficiency, with consistent performance over time thanks to optimised technical solutions.
Robust design, engineered for intensive cycles and continuous operation in harsh industrial environments.
Suitable for high-power applications, with high performance and high reliability even under extreme conditions.

FAQ - Radial Piston Hydraulic Pumps
They are ideal for systems requiring very high pressures up to 700 bar, differentiated flow rates or several independent circuits within the same system.
They offer extreme performance and great flexibility, thanks to the possibility of obtaining several independent flow rates with a single pump, ensuring maximum power and precision.
When pressures above 350-400 bar are required, or when a single system must supply different functions with separate flow rates, without resorting to multiple pumps.
