Method for reaching air-tightness of the joint between the casing of an impeller pump and its cover

Resumo

A method is considered to reach the air-tightness of the flange joint of the casing of an impeller pump with its cover using an anaerobic sealant instead of a gasket made of a thermoplastic material. The possible causes of leakage of working fluids that are related to the errors of machining flange surfaces and the specific features of their assembly are shown. The properties of anaerobic sealants that ensure the air-tightness of the flange joints are presented.
