Sliding Vane Pumps for Industrial Applications

Corken’s positive displacement sliding-vane industrial pumps are known as a Coro-Vane® pump. The self-adjusting sliding vanes deliver higher pumping efficiencies and extend the life of the pump. The CD-model Coro-Vane pumps have a replaceable cam and sideplates. The rotor, cam, sideplates, seals, and bearings are easily replaced by simply removing the pump cover. Most of Corken's sliding vane pumps are equipped with an adjustable internal relief valve.

We offer several models of positive displacement, sliding vane pumps for wide range of vapor pressures, differential pressures, and viscosities. The drive options include gear reduced and belt driven.

Liquids suitable for our sliding vane pumps include but are not limited to aviation fuel, fuel oil, lube oil, solvents and liquefied gases such as LPG, ammonia, and CO2. Each product group listed below is designed for the characteristics of a various liquids. To find a sliding-vane pump for your application, select from one of the following product groups.
