Frequently Asked Questions (FAQ)
Q: Is this A10VO28 pump a direct replacement for my original Rexroth unit?
A: Yes, as long as your pump series (A10VO28) and control/shaft parameters match, this pump assembly acts as a direct bolt-on replacement.
Q: What is the difference between open-circuit and closed-circuit pumps?
A: The A10VO28 is an open-circuit pump, meaning fluid flows from the hydraulic reservoir into the pump and returns to the tank via control valves (unlike closed-loop pumps like the A4VG series).
Q: What pre-installation procedures are required before startup?
A: The pump casing must be completely filled with fresh, clean hydraulic fluid through the top drain port prior to engine startup to avoid cavitation and dry running.
Q: How long does global shipping take?
A: In-stock pumps are usually dispatched within 3–5 business days, with express air shipping available for urgent machine-down situations.
