Leakage in mechanical seal

Compressors, Pumps, and Pipeline Fittings


It is shown that when sucker-rod pumps are used, fluid leakage in seals of plunger-cylinder and valve pair through hole and radial slot is proportional to the area of the flow section and is also dependent on the shape of the latter. A new type of mechanical seal has been developed that reduces leakage significantly and increases efficiency and nonfailure operating life of piston or plunger pumps.
