Hydraulic Power Unit

Complete Comfort and Roll Control Solutions

Quantum Marine Stabilizers


The QP4040C hydraulic power unit provides the fluid power necessary to articulate the stabilizer fins. Ideal for narrow spaces with a limited footprint and full headroom.

Designed to consolidate maximum machinery output into a narrow footprint. This unit can be disassembled into three components: lower motor, middle motor and the tank. The QP4040C power unit consolidates on a single skid the hydraulic drive train on an aluminum frame with drip tray, stainless steel oil reservoir with associated gauging and sensors, as well as return filtration and oil cooler. The system is designed to accommodate full, surrounding sound shields with in and outtake baffles. In addition, hydraulic dampener(s) may be mounted on the pressure manifold to eliminate structure borne noise. Also available with a maximum output of 75kW / 100hp.

Key advantages of the
QP4040C Hydraulic Power Unit


Simple Installation

The QP4040C is designed to incorporate maximum hydraulic function within a single “plug and play” assembly. Thus, straight-forward connections for mechanical installation, as well as hydraulic and cooling pipe work are at the heart of the QP4040C design.


The power unit only draws the minimum power necessary to operate the hydraulic components on demand, thus reducing the load on the vessel’s electrical power and cooling systems.

Minimal noise

Quantum’s power units with the WhisperTM vane pumps utilize a two-point isolation system to bring both noise and vibration levels down. Hydraulic noise suppressors are attached directly at pump discharge to minimize hydraulic noise in the pipes.


The durable high gloss paint finish rivals the finish presented in public spaces of even the highest quality yachts. Details such as polished stainless steel tubing and black anodized manifolds make this unit a work of art as well as a practical marinegrade solution.
