ABSTRACT:
A high-pressure transfer device and method of utilization thereof are provided which allow flexing of the transfer device housing, and significant wear of the relatively rotatable components, without leakage. The transfer device includes a rotor having at least five diametrically through-going pockets, and enclosed by a housing having an exterior periphery and four ports disposed around the exterior periphery for registry with inlets to and outlets from the pockets. An interior screen is provided in each rotor pocket, and the rotor is cylindrical. Sealing structures are disposed between the rotor and housing around the external periphery of the rotor and interior periphery of the housing, the sealing structures maintaining effective sealing despite any relative movement between the housing and rotor, such as radial deflection of the housing. The sealing structures preferably comprise removable sealing shoes of a less wear-resistant material than the rotor. Pressure compensators for applying a force proportional to the liquid pressure at a particular point to maintain the sealing structures in sealing relationship with the rotor are provided at all of the ports, and accessory pressure compensators are provided adjacent the high-pressure ports.
