A sliding vane pump is a common type of hydraulic pump used to convert mechanical energy into the flow of liquid. Its working principle is based on one or more vanes (also known as blades, wings, or vanes) sliding within the rotor of the pump as it rotates, thereby generating the pumping effect for liquids. In this article, ATO industrial automation will briefly introduce it to you, including its basic structure, working principle, characteristics, applications and precautions etc., to help you have a better understanding of it.
