Fixed Displacement Axial Piston Pumps BF20 Series
- Displacement 56, 80, 107 cmᶟ/rev
- Rated pressure 400 bar
- Maximum pressure 450 bar
BF20 Series fixed-displacement bent-axis axial piston pumps: PBF20.56R, PBF20.80R, PBF20.107R, PBF20.56L, PBF20.80L and PBF20.107L feature a high-strength cast-iron housing and are designed for hydraulic systems of mobile machinery operating under heavy loads. Their robust design makes them suitable for construction, forestry and agricultural machinery, material-handling equipment, municipal vehicles, as well as machinery used in the mining and oil and gas industries.
Applications:
- construction machinery;
- agricultural machinery;
- forestry machinery;
- material-handling equipment;
- municipal machinery.
According to the applicable technical specifications (TU), Hydrosila products are not classified as dual-use products.
BF20 Series pumps feature a fixed-displacement bent-axis axial piston design. The high-strength cast-iron housing provides structural strength and allows reliable operation under high hydraulic loads and temperature variations.
The 40° bent-axis angle provides a compact design and high operating performance. The bimetallic cylinder block offers high wear resistance, while tapered roller bearings allow the drive shaft to withstand significant radial and axial loads. Tapered pistons with compression rings and the design of the rotating group ensure stable pump operation over a wide speed range.
The mounting flange complies with ISO 3019-2. Drive shaft versions are available in accordance with DIN, SAE and GOST standards.
