Frequently Asked Questions
1. What is the A10VSO45 series pump?
The A10VSO45 is a variable displacement axial piston pump with a
swashplate design, designed for open-circuit hydraulic systems. It
delivers flow proportional to drive speed and displacement, with
stepless flow adjustment via swashplate angle control. Key features
include high efficiency, low noise, and a compact design with
ISO/SAE mounting flanges.
2. What are the technical specifiions?
- Displacement: 45 cc/rev (other sizes: 28, 71, 100, 140 cc/rev
available)
- Pressure Ratings:
- Nominal pressure: 280 bar (28 MPa)
- Peak pressure: 350 bar (35 MPa)
- Control Options: DG (direct actuation), DR (pressure control), DFR
(pressure/flow control), DFLR (pressure/flow/power control), and
more
- Speed Range: Up to 1,500 rpm (varies with model and fluid
viscosity)
3. What appliions is it suited for?
The pump is widely used in:
- Industrial machinery (e.g., presses, plastic injection molding)
- Mobile hydraulics (construction, mining equipment)
- Marine and aerospace systems due to its high power-to-weight ratio
and reliability
4. How does the variable displacement mechanism work?
Flow is adjusted by changing the swashplate angle via an external
control mechanism (e.g., pressure compensator or manual
adjustment). This allows the pump to deliver only the required
flow, reducing energy consumption.
5. What maintenance is required?
- Regularly check for leaks, abnormal noise, or pressure fluctuations
- Monitor fluid cleanliness (ISO 4406 Class 18/16/13 recommended)
- Replace seals and bearings per the manufacturer's service intervals
6. What are common troubleshooting steps for flow/pressure issues?
- Flow instability: Check for air ingress, clogged filters, or worn
control pistons
- Pressure drops: Inspect relief valves or compensator settings
- Noise: Verify alignment of the pump and motor shafts, and ensure
fluid viscosity is within specs
7. Is the A10VSO45 compatible with alternative fluids?
While optimized for mineral oil, some models (marked "E") can use
HFA/HFB/HFC fluids with reduced performance parameters.
8. Where can I purchase genuine A10VSO45 pumps?
Authorized distributors like Shanghai Weimi Electromechanical and
Kemai Automation offer original Rexroth pumps with warranties and
technical support.
9. Can it be used in a multi-pump configuration?
Yes, the through-drive shaft allows mounting additional gear pumps
or piston pumps (up to 100% drive capacity).
10. What warranty and after-sales support are available?
Standard warranties cover 1 year for manufacturing defects.
Extended support includes on-site troubleshooting and spare parts
supply.
