Abstract
A glandless centrifugal pump and wet electric motor unit for use in fossil-fired power plants has a cover which is sealingly connected with one end of the main portion of the motor housing and contains one or more cyclone separators for solid impurities. Liquid to be relieved of solid impurities is fed into the cover by way of a tangential inlet and such liquid passes through a coarse-mesh sieve which intercepts large solid impurities before the thus filtered liquid reaches the cyclone separator or separators. The separator or separators admit cleaned liquid into a channel provided which is provided therefor in the housing of the motor. The smaller solid impurities accumulate in a chamber which can be cleaned by way of a sealable opening while the cover remains attached to the main portion of the housing. The area around the sieve becomes accessible when the cover is detached from the main portion of the motor housing; such detachment need not take place for the express purpose of removing larger impurities but rather when the attendant wishes to inspect the bearings in the motor housing.
