V-PAK SERIES – Variable Displacement (2.0 – 36.0 GPM)

Hydraulic Power Units (HPUs) operate the blade pitch systems with consistency, optimizing the energy output from the turbine and minimizing the loads and vibration on the structure. These space-saving, vertical style HPUs are available with gear or piston pumps for quieter, leak-free operation, protecting pumps from contamination and extending pump life. Standard Parker filtration on each unit helps ensure a long service life.
