TECHNICAL SPECIFICATION DOCUMENT HYDRAULIC WHISPER™ VANE PUMP KIT Our Whisper™ hydraulic vane pump upgrade kit provides the quietest solution to date to power both underway and ZeroSpeed™ stabilizer fins. Quantum Whisper™ vane pumps can be paired with a variety of existing Quantum stabilizer hull unit sizes and powerpacks, based on vessel requirements, creating the lowest possible operating noise levels. Designed to produce maximum hydraulic output from a "quiet" package, this compact pump can be retrofitted easily into existing Quantum Hydraulic Power Units1. The PVX Whisper™ vane pump kit consists of the pump, bellhousing, coupler, and 4 new hoses. The PVX Whisper™ vane pump is a rugged and precision-built component which can be depended upon to supply quiet hydraulic power for Quantum stabilizer systems. • SIMPLE INSTALLATION: Our Whisper™ vane pumps are designed to incorporate maximum hydraulic function within a single "plug and play" kit assembly. Straight- forward connections for both the mechanical installation and the hydraulic pipe work are at the heart of the vane pump design and our kit components. • EFFICIENT: The Whisper™ vane pump draws the minimum power necessary to operate the hydraulic components relative to demand, reducing the load on the vessel's electrical power and cooling systems. • MINIMAL AIRBORNE NOISE: Quantum's Whisper™ vane pumps bring both noise and vibration levels down. Hydraulic noise suppressors attached directly at the pump discharge further minimize hydraulic noise in the pipes. • APPEARANCE: 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 marine- grade solution.
