About hydraulic pumps
Axial piston pump Hansa Flex HK PBA 056 L 80 51 SF is the source of flow and pressure in a hydraulic system. We supply axial piston, gear and vane pumps from Danfoss, Bosch Rexroth, Parker, Casappa, Bucher and Hydrokraft.
Pump types and applications
| Type | Pressure | Application |
|---|---|---|
| Gear | up to 250 bar | Simple drives, mobile machinery, lower cost |
| Axial piston | up to 450 bar | High pressure, variable displacement |
| Vane | up to 175 bar | Machine tools, industry, low noise |
How to select a pump
- Displacement — from required flow: V = Q × 1000 / (n × η), where η ≈ 0.9–0.95.
- Pressure — based on the nominal duty, checked against peak pressure.
- Speed — within the catalogue range, typically 1500–3000 rpm.
- Mounting — flange (SAE A/B/C/D), shaft type, rotation direction, port positions.
Common mistakes: sizing by motor power, ignoring oil viscosity and rotation direction, and omitting a suction filter.
Frequently asked questions
Can an alternative replace the original?
Yes, if displacement, mounting dimensions, shaft type and rotation direction match. We match alternatives against the nameplate.
What to check if performance drops?
First check the filter, oil viscosity and tank level. Then pump wear: falling volumetric efficiency shows up as higher temperature and lower pressure under load.
What is the lead time?
Typically 7–30 days depending on supplier stock. The exact lead time is confirmed after we check the item.
