Outstanding performance

Build machines that provide unprecedented controllability, efficiency, and productivity with Vickers by Danfoss medium-duty open-circuit variable-displacement piston pumps. Leading the industry in noise reduction, compact size, and pressure rating, these pumps deliver reliable power across the spectrum of industrial applications.

Pumped up performance – ​ Introducing the New PVM Code B

Engineered to take the renowned performance and reliability of our PVM piston pump to new heights, the new Code B design delivers enhanced components and features to maximize the pump lifespan. In addition, the standardized housing and components simplifies manufacturing processes and reduces lead times.

Optimized engineering 

  • Quietest piston pumps in their class
  • Compact design delivers more power in less space
  • Up to 4,600 psi continuous pressure
  • Saddle-type swashplate with steel-backed polymer bearing for improved life
  • Unique tapered envelope design that reduces vibration

Improved efficiency and cost savings

  • Optional power control helps the machine use power more accurately
  • Variable-speed technology generates power far more efficiently than fixed-speed pumps
  • Better energy efficiency eliminates the need for costly, energy-consuming cooling equipment

Maximum flexibility for every industry and application

  • Wide displacement range to meet virtually any application need
  • ATEX certification helps ensure safe operation in explosive environments
  • Adjust power settings in the field to easily fine-tune performance

Product range

PVM Code B

In addition to industry leading in noise reduction, compact size and pressure rating, the new PVM Code B open-circuit piston pump offers new design enhancements including: 

  • High pressure shaft seal standard - longer life, minimize leakage risk
  • Enlarged case port - better case draining
  • Standardized design - better lead times
  • Technology-Axial piston
  • Displacement – 18 - 141 cc (1.1 to 8.6 cu in)
  • Continuous pressure rating - 315 bar (4,600 psi)

PVM Code A

Known for versatility and efficiency, PVM series open-circuit piston pumps also lead the industry in low noise, compact size and higher-pressure rating.

  • Technology-Axial piston
  • Displacement – 18 - 141 cc (1.1 to 8.6 cu in)
  • Continuous pressure rating - 315 bar (4,600 psi)

PVXS 180 – 25 design

The PVXS design 25 is a hybrid pump, utilizing the strengths of the PVM and Hydrokraft product lines. The pumps are built with a robust housing, oversize shafts and bearings, and strong rotating kit from the Hydrokraft product line designed for continuous pressures of 350 bar, in addition to controllers from the PVM range. The result is a pump rated at 315 bar continuous operating pressure, built with components capable of much higher pressures, making it a strong and reliable product in the medium pressure range. 

  • Maximum pressure up to 350 bar.
  • Rated speed up to 1800 rev/min. Higher speeds possible.
  • Rotating and pressure- loaded parts are pressure balanced.
  • Through-drive enables multiple pump installations from a single shaft. Multiple pump combinations​ are also available.
  • Fast response times.
  • Technology-Axial piston
  • Displacement - 180 cc (11 cu in)
  • Continuous pressure rating - 315 bar (4,600 psi)


Both fixed and variable displacement models make up this range of axial piston pumps. Their high-performance ratings and efficiencies are achieved with a variety of hydraulic fluids. 

  • Standard adjustable maximum volume screw and gage ports provide flexibility.   
  • High overall efficiency reduces operating costs.  
  • Robust shaft bearings extend operating life and lowers maintenance costs.  
  • Controllers available to enhance the machine control and energy saving.
  • Technology-Axial piston
  • Displacements from 10 - 197.5 cc [0.64 to 12 cu in] 
  • Continuous pressure ratings up to 210 bar [3,000 psi]


PVQ piston pumps are in-line, variable displacement units and operate at low sound levels, typically less than the sound of the electric motor that is driving it. Displacement is varied by means of pressure and/or flow compensator controls while an assortment of control options offers maximum operating flexibility.

  • Noise is reduced by a patented timing arrangement that also produces low pressure “pulses” in the outlet flow
  • Capable of operating with water-content and phosphate ester fluids, in addition to the typical petroleum based and synthetic fluids.
  • Available in a thru-drive configuration to accommodate a multitude of applications
  • Technology-Axial piston
  • Displacements from 10 - 45cc [0.6 to 2.75 cu in]
  • Continuous pressure ratings up to 210 bar [3,000 psi]
