ABSTRACT:
Centrifugal pipeline pumps for crude oil and other hydrocarbon liquids are provided with removable cover members between the seal housing portions of the pump casing and the outboard bearing housing portions of the pump, which cover members have vapor adsorption filters supported thereon and in fluid flow communication with the pump fluid leakage collection spaces formed between the pump shaft seal housings and the pump shaft bearing housings. The cover members and vapor adsorption units may be easily removed from the pump casing in assembly to provide access to the pump shaft seals for inspection or repair.
