Frequently Asked Questions (FAQ)
Q: What is the design concept of the Rexroth LA10V 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 open circuits.
Q: How does the displacement adjustment work on these pumps?
The output flow is proportional to both the drive speed and the displacement. By adjusting the angle of the swash-plate, the flow can be infinitely varied to match operational requirements.
Q: What are the main differences between Series 52 and Series 53?
Series 52 and Series 53 cover different size ranges (NG). Series 52 is available in sizes 10, 28, 45, 60, and 85. Series 53 covers sizes 18, 28, 45, 63, 72, 85, and 100, featuring refined control device options and port designs.
Q: What types of control devices can be configured?
Both series support a wide range of controls, including hydraulic pressure controllers (DR), flow controllers (DFR/DFR1), remote pressure cut-offs (DRG), electrical negative/positive controls (ED/ER series), and advanced power controls (LA.D series).
Q: What seal materials are used in the LA10V pumps?
The standard seal option provided in the order code is FKM (fluor-caoutchouc), designated by the code letter "V" in the order code sequence.
Q: Are both clockwise and counter-clockwise rotations available?
Yes, the rotation direction is determined when viewed on the drive shaft. You can specify clockwise (R) or counter-clockwise (L) in the ordering code.
