Abstract: Wear rings for electric submersible pump (ESP) stages are provided. An example ESP has one or more running clearance seals reinforced with high-hardness wear rings. Ceramics and carbides may provide the high hardness for the wear rings, but such substances are more brittle than metals and have different coefficients of thermal expansion than metals. For protection, each high-hardness wear ring may be mounted with an elastic cushioning scheme. The elastic mounting preserves each wear ring from shock, stress, and breakage from thermal expansion and contraction of an adjacent pump part. Each high-hardness wear ring may also have a low-stress driving mechanism that cushions the rotational force imparted to the wear ring when the ESP pump is being powered. In some implementations, the elastic mounting scheme may also serve as the low-stress driving mechanism for the high-hardness wear ring.
