A fluid pump having a pump housing, and an impeller in the housing and coupled to the drive shaft of a drive motor. An improved main seal is provided in the housing to seal the hole through which the drive shaft extends. The seal includes a carbon seal member having a flat end face in sliding relationship to the flat end face of a ceramic seal rotatable with the drive shaft and the impeller. The seal further includes a pre-loaded element which forces the two seal faces together. An improved mounting bracket is provided to mount the drive motor and the pump housing on a fixed support. The mounting bracket includes a central mounting plate and a pair of inclined, side wings which extend from the pump housing toward the drive motor so as to eliminate the need for a second bracket on the opposite side of the motor.
