A rotary pump for pumping compressible fluid comprising an eccentrically mounted rotor and a stator . The stator comprises a stator inner liner that is free to rotate, driven directly or in response to rotation of the rotor such that the relative velocity between the outer surface of the rotor and the inner surface of the stator is reduced. The vanes are held at each end by sockets in the rotor and stator . The vane and socket coupling provides fluid sealing without liquid lubricant. Opposing solid lubricant and hard surfaces are used on contact surfaces between the elements.
