FAQ:

4. What are the installation requirements?

• Flange types: ISO 2-hole (A) or 4-hole (B) for larger sizes (e.g., 140 cc/rev).

• Shaft options: Keyed straight shaft (P), SAE splined shaft (S/R).

• Seals: NBR (standard) or FKM (fluorocarbon) for high-temperature fluids.

5. What are common troubleshooting issues?

• Low/no flow: Check for clogged filters, air ingress, or incorrect swash plate angle.

• Pressure fluctuations: Inspect control piston wear or dirty hydraulic oil.

• Overheating: Ensure proper cooling/lubrication and check for internal leakage.

• Noise/vibration: Verify alignment (max. 0.1mm deviation) and suction line integrity.

6. How to order or customize?

• Model example:

A10VSO140DR/32R-VPB22U00E-S1550

  ◦ 140: Displacement (cc/rev).

  ◦ DR: Pressure control.

  ◦ 32R: Series and rotation (R = clockwise).

  ◦ VPB22U00E: Port and seal options.

• Lead time: Typically 15 days for standard models.
