High Pressure Capacity Pumps

|
|
Available in multiple piston variations, Bosch Rexroth fixed displacement radial piston pumps offer high pressure capability, in excess of 9,000psi/600 bar. Single bank piston arrangements are possible for (3) and (5) pistons models, while a “double bank” version incorporates (10) pistons. Outlet ports for the radial piston pumps can be combined or individual, permitting greater flexibility in separating functions from a single pump source. Displacements begin at 1.5cc/rev with 14 models spanning displacement up to 19.4cc/rev. The fixed displacement radial piston pump from Bosch Rexroth provides the perfect solution for applications where high pressure is the criteria.
