WebRotary Actuators Fluid Power Circuits and Controls, John S.Cundiff, 2001 INTRODUCTION Concepts developed for pumps are applicable to hydraulic motors. Motors convert fluid energy back into mechanical energy and thus are the mirror image of pumps Typical motor designs are gear, vane and piston. WebRotary vane pumps hold many advantages over centrifugal pumps in the areas of maintaining flow rates and optimizing energy efficiency – especially if the application requires the handling of non-abrasive liquids at temperatures less than 500°F (260°C) and with viscosities less than 22,500 cP.

WebA vane pump is a type of rotary positive displacement pump. It consists of vanes mounted radially on a cylindrical rotor, which is eccentrically located in the pump casing. The vanes maintain a close seal against the casing wall. During a rotation cycle, the volume between adjacent vanes changes because of the eccentric mounting position ... WebApplications. Rotary vane vacuum pumps come in two types: those used to generate coarse vacuum levels (760 to 1 Torr) and those used to generate rough vacuum levels (760 to 10 -3 Torr). Design of these pump types varies primarily based on the number and tolerance of vanes in the pumping chamber. Rough rotary vane pumps, which are commonly used ...
