Reliable power in the toughest conditions
Engineered to excel in demanding industrial applications, Hydrokraft heavy-duty open-circuit piston pumps feature variable and fixed displacements, a modular design and flexible mounting options. Use Hydrokraft piston pumps for tough applications such as primary metals power units, marine cranes, and thrusters.
Fitting for a wide range of applications
Hydrokraft open-circuit piston pumps feature industry-standard mounting capabilities and a modular construction, making these open-circuit pumps a perfect fit for many applications. Choose from fixed or variable Hydrokraft options in sizes to meet your needs: PVX, PVW, PFX, PFW, PVZ.
Increased durability, decreased noise levels
The pumps come in a robust housing enclosure, which increases pump durability and reduces operating noise. Their tension-rod design also contributes to quieter operation.
Reliable and long-lasting
Hydrokraft open-circuit piston pumps are axial piston pumps with a swash plate design for reliable operation and a longer life. Plus, their rotating and pressure-loaded parts are pressure-balanced for greater efficiency and serviceability.
Mobile pump installations and combinations
- Through-drive design allows for multiple pump installations from a single shaft
- Foot mounting option allows for easy bedplate installation
- Multiple pump combinations available
