Hydraulic pumps are essential components of hydraulic systems, generating flow and pressure to power actuators and circuits. Sauer-Danfoss is a well-known manufacturer of high-quality hydraulic pumps for industrial and mobile applications. This post will cover the main types of pumps offered by Sauer-Danfoss and their key features and applications.
Product Range By Sauer-Danfoss
Sauer-Danfoss offers a wide variety of hydraulic pumps to meet the needs of different systems and equipment, including:
- Gear Pumps – Used for flows up to 300 L/min and pressures to 420 bar. Ideal for proportional control and efficiency.
- Vane Pumps – Provide flow up to 850 L/min and pressures to 420 bar. Offer quiet operation, smooth performance and robust design.
- Piston Pumps – Deliver flows up to 2200 L/min and pressures to 420 bar. Feature precision control and repeatability for demanding applications.
- Axial Piston Pumps – Generate flows up to 5000 L/min and pressures to 420 bar. Provide high power density and efficiency in a compact design.
- Orbital Piston Pumps – Used for flows up to 1200 L/min and pressures to 420 bar. Offer bi-directional operation, inherent cooling and high reliability.
- Bent Axis Pumps – Generate flows up to 4800 L/min and pressures to 420 bar.Provide pressure compensation and virtually pulse-free flow.
- Fixed Displacement Pumps – Ideal for basic flow and pressure requirements. Offer lower cost and simple controls.
- Variable Displacement Pumps – Flow and pressure vary proportionally with input. Used when system demands change continuously.
Key Features Of Sauer-Danfoss Hydraulic Pumps
Sauer-Danfoss hydraulic pumps offer several features that enable high performance in demanding applications:
- Efficiency – Many models achieve up to 98% mechanical efficiency to reduce power losses.
- Durability – Hardened steel components and ceramic seals provide long service life, even in continuous duty.
- Controllability – Variable displacement pumps precisely match system demands to optimize efficiency.
- Ripple – Low hydraulic pressure and flow ripple enable smooth actuator performance.
- Reliability – Rugged designs and few wear items result in long intervals between maintenance.
- Portability – Many pumps are available in axial, radial and bent axis versions for flexibility.
- Options – A range of control, mounting and porting options enable customization.
- Pressure – Models are available for applications requiring up to 420 bar (6000 PSI) operation.
- Flow – Flow rates range from under 1 L/min to over 5000 L/min, covering all system needs.
