What is a Denison PAVC Pump?

The PAVC Series is a variable displacement pressure-compensated axial piston pump designed to deliver hydraulic flow according to system demand.

Unlike fixed displacement pumps, PAVC pumps automatically adjust output flow, reducing energy consumption and heat generation.

This feature makes them highly suitable for:

• Marine hydraulic systems
• Deck cranes
• Hydraulic power packs
• Winch systems
• Offshore hydraulic equipment
• Industrial machinery

SM MARINE SERVICE™ regularly supports vessel operators requiring replacement pumps, repair services, spare parts, and technical support for the complete PAVC series.
