Frequently Asked Questions (FAQ)
What is the design concept of the Rexroth LA10V axial piston pump?
The Rexroth LA10V is a variable displacement pump featuring an axial piston rotary group in a swash-plate design, specifically engineered for hydrostatic drives operating in an open circuit.
How does the flow control mechanism work on these pumps?
The output flow is directly 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 system requirements.
What pressure ratings do the Series 52 and 53 pumps support?
Both series are designed with a nominal pressure capability of 250 bar and a maximum peak pressure limit of 315 bar.
What are the differences in control device options between Series 52 and Series 53?
While both offer standard hydraulic pressure control (DR) and flow control (DFR/DFR1), Series 53 expands the options to include integrated power controls with pressure cut-off (such as LA5D through LA9D) and remotely operated hydraulic controls.
What sealing material is standard for these pumps?
FKM (fluor-caoutchouc) seals are standardized (designated by the code letter "V" in the ordering code) to provide excellent thermal and chemical resistance.
Which mounting flange standards are compatible with these series?
Depending on the specific configuration and pump size, the pumps support ISO 3019-2 (ISO 2-hole) and ISO 3019-1 (SAE 2-hole or 4-hole) mounting configurations.
