In demanding mobile hydraulic applications, durability and performance under harsh conditions is a must. Sauer Danfoss Series 45 pumps have become an industry standard for their unmatched ruggedness and reliability in tough off-highway equipment. Read on to learn what makes the sauer danfoss pump series 45 design excel and how proper maintenance keeps these pumps delivering optimum flow and pressure.
Overview of the Series 45 Pump Platform
The Sauer Danfoss Series 45 refers to a lineup of medium-duty axial piston pumps designed for the fluid power needs of mobile machinery. Available in displacement ranges between 2-253 cc/rev, the family covers a wide variety of flows and pressures.
The pump configuration consists of a slanted axial piston block actuated by a swashplate angle. As the block rotates, fluid gets drawn in and pressurized with each piston stroke. The result is smooth, continuous flow perfect for driving hydraulic cylinders and motors.
A proven in-field workhorse, the Series 45 design provides exceptional power, kecekapan, and controllability for compact and utility-class equipment.
Key Attributes Of The Series 45 Pumps
Several key advantages make Series 45 units a top choice for OEM integration:
- Durable axial piston design – Built for thousands of hours of reliable service.
- Pressure compensated – Maintains consistent output regardless of load changes.
- Anjakan berubah-ubah – Flow and pressure can be adjusted to match demand.
- Low noise and vibration – Smoother output reduces noise emissions.
- Kecekapan tinggi – Sehingga 92% translates to less fuel consumption.
- Dynamic braking – Enables rapid hydraulic deceleration.
- Responsive controls – Quickly adapts output via electrical or mechanical control.
- Padat, flexible installation – Suits tight spaces and allows multiple configurations.
Together these attributes enable top hydraulic performance and efficiency to maximize machine productivity.
Maintenance Tips for Series 45 Pumps
To keep Series 45 pumps operating at peak performance, Sauer Danfoss advises:
- Regular fluid sampling – Change fluid and filters per intervals.
- Inspecting pumps for leaks – Repair any external leakage immediately.
- Monitoring pressure and noise – Investigate any spikes or abnormal sounds.
- Checking mounting torques – Re-torque loose fasteners.
- Clearing debris – Keep pump exteriors and coolers clear of mud or obstructions.
- Following rebuild schedules – Rebuild pumps at suggested intervals.
- Using only genuine spare parts – Subpar parts compromise reliability.
Proactive maintenance paired with the inherent ruggedness of the Series 45 pumps ensures the longest and most trouble-free operation.
Getting the Most from Your Investment
