Leak resistant pump
Abstract:
An improved leak resistant pump with sealing system for preventing leakage of a fluid from a housing. The sealing system has a housing, wherein the housing contains the fluid. A shaft penetrates the housing. A narrow fluid flow path directs a leaked fluid from the housing. A labyrinth seal constrains the leaked fluid from the narrow fluid flow path. A stationary seal constrains a flow of the leaked fluid from the labyrinth seal and a grease seal for constraining the flow of the leaked fluid from the stationary seal.
