Medium-duty open-circuit piston pumps

With compact designs that deliver more power in less space, Danfoss’ medium-duty open-circuit piston pumps are the quietest in their class and feature a unique tapered envelope that reduces vibration. A saddle-type swashplate and steel-backed polymer bearing increase product lifespan while supporting continuous pressures up to 315 bar [4,600 psi].

PVB series pumps
PVB series axial piston pumps are available with either fixed or variable displacement. Their high performance ratings and efficiencies are achieved with a variety of hydraulic fluids.
PVM series code A pumps
Known for versatility, efficiency, and high pressure ratings, our compact PVM series code A open-circuit piston pumps offer industry-leading low noise levels, reducing the need for expensive sound enclosures or inline pulsation dampers.
PVM series code B pumps
In addition to industry-leading noise reduction, compactness, and pressure rating, the PVM series code B open-circuit piston pump offers new design enhancements including a standard high-pressure shaft seal for longer life, an enlarged case port for better draining, and a standardized design to improve lead times.
PVQ series pumps
PVQ series piston pumps are in-line variable-displacement units that typically produce less sound than the electric motors driving them. Their displacements are changed by means of pressure and/or flow-compensator controls, and an assortment of control options offers maximum operating flexibility.
PVX series 25 design pumps
Available with displacements from 66 cm³ to 250 cm³ [4.1 in³ to 15.3 in³] for continuous pressures up to 315 bar [4,569 psi], these axial piston pumps feature a swashplate design with a robust housing, a strong rotating kit, and oversized shafts and bearings for reliable operation and long life.
PVMX series pumps
Vickers by Danfoss PVMX pumps feature a low-noise design and a variety of control options for operation at 350 bar [5,070 psi] continuous and 420 bar [6,090 psi] peak pressures. High-load bearings and a stiff drive shaft help provide long service life at rated industrial conditions, while efficient over-center operation improves responsiveness and stability, reduces wear on the swashplate by maintaining proper contact, and ensures minimum displacement.
