The authors describe the shortcoming of slurry pumps used by the customers. Pump wear resistance and life time are provided by lining of such wearing components, as casing, frame liner inserts, pump runner, with highquality polyurethane elastomers. To extend the service life of polyurethane components of a pump flow section with all hydrodynamic parameters being unchanged SOMEX ZAO has developed a method of reinforcement to form stresses in a polyurethane layer.
