Introduction
The Rexroth A2VK hydraulic pump series is a proven bent-axis axial-piston platform engineered for high reliability, serviceability and energy efficiency in mobile and industrial hydraulics. Available in common frame sizes such as A2VK12, A2VK28, A2VK55 and A2VK107, the family covers low- to high-flow requirements while supporting continuous operation across 735–1800 rpm and rated system pressures of 250–315 bar. BAOLILAI supplies OEM-compatible units with factory testing and a one-year warranty; request complete PDFs at www.baolilai-pump.com/contact_us/.

Design highlights — why A2VK suits modern machines
• Bent-axis geometry delivers high volumetric efficiency and compact power density.
• Low leakage at high pressure reduces heat build-up, improving thermal stability in continuous-duty circuits.
• Reinforced housings and heavy-duty bearings provide resistance to pressure transients and mechanical shock.
• Options for explosion-proof variants, corrosion coatings and special sealing enable safe operation in hazardous or marine environments.

Typical machine integrations (examples & OEM sites)
The A2VK series is widely used as main and auxiliary pumps across agriculture, construction, engineering and mining systems. Sample integrations:

• Agricultural tractors and combine drives — large implements and hydrostatic transmissions (example OEM sites: www.deere.com, www.caseih.com).
• Excavators and wheeled loaders — swing, travel and implement circuits that require continuous high flow (example OEM sites: www.cat.com, www.volvoce.com).
• Mining shovels and haul trucks — high-duty, high-pressure hydraulics where durability is critical (example OEM sites: www.komatsu.com, www.liebherr.com).
• Industrial presses and marine deck equipment — closed-loop drive systems benefiting from A2VK’s compact package (example OEM sites: www.jcb.com, www.doosanequipment.com).

System integration checklist (practical guidance)

1. Match pump displacement to system flow and desired shaft speed — calculate target rpm = (system flow L/min × 1000) ÷ displacement cc/rev, and allow margin for efficiency losses.
2. Filtration & cleanliness — maintain ISO cleanliness per OEM recommendations; use fine filtration (β10 / β16) to protect piston group and valves.
3. Thermal management — add coolers for sustained high-power cycles; monitor oil temperature.
4. Transient protection — fit accumulators or pressure dampers to mitigate spikes; specify reinforced option where shock loads occur.
5. Installation — ensure correct coupling alignment and mounting torque to avoid shaft and bearing overload.

Durability & safety features
A2VK pumps can be specified with explosion-proof housings and high-temperature seal materials for use in hazardous zones or extreme climates. Reinforced porting and hardened swash plates increase resistance to abrasive contamination and extend service intervals. BAOLILAI provides custom surface treatments and protective coatings for offshore, desert or corrosive environments.

FAQ

Q1 — What operating pressures and speeds are typical for A2VK pumps?
A1 — The A2VK family is commonly applied at 250–315 bar and speeds within 735–1800 rpm; exact limits depend on model and OEM configuration.

Q2 — How do I choose between A2VK12 and A2VK107?
A2 — Select by required displacement (flow) and torque. Use A2VK12/A2VK28 for lower-flow auxiliary drives, A2VK55/A2VK107 for primary pumps on larger machines.

Q3 — Are explosion-proof and corrosion options available?
A3 — Yes. BAOLILAI supplies explosion-protected variants and special coatings; specify environmental options at the time of order.

Q4 — Where can I download CAD, curves and PDF?
A4 — Request full technical files and datasheets at www.baolilai-pump.com/contact_us/ or browse product listings at www.baolilai-pump.com.

Conclusion
The Rexroth A2VK hydraulic pump range (A2VK12, A2VK28, A2VK55, A2VK107) delivers efficient, compact hydraulic power for modern OEM systems. With proven pressure resilience, explosion-proof options and global OEM compatibility, these pumps are suitable for the toughest agricultural, construction, mining and industrial applications.
