Frequently Asked Questions (FAQ)
The Rexroth LA10V series is a variable pump featuring an axial piston rotary group in a swash-plate design, specifically engineered for hydro-static drives in open circuits.
The output flow is proportional to both the drive speed and the pump's displacement. By adjusting the angle of the swash-plate, the flow can be infinitely varied to match application requirements.
For Series 52, geometric displacements are available in sizes 10, 28, 45, 60, and 85. For Series 53, the size configurations expand to include 18, 28, 45, 63, 72, 85, and 100.
The pump offers multiple splined shaft options conforming to ANSI B92.1a (such as standard shaft S, higher input torque shaft R, reduced diameter shaft U, and higher torque shaft W) as well as a parallel keyed shaft option conforming to DIN 6885 (shaft P).
The standard seal material utilized is FKM (fluor-caoutchouc), denoted by the code "V" in the ordering structure.
The pumps support various control devices including hydraulic pressure controllers (DR), flow controllers (DFR, DFR1, DRSC), pressure cut-offs (remotely operated DRG, or electric negative/positive controls ED/ER), and power control with pressure cut-off (LA5D through LA9D).
