Abstract
A pump body has a cavity containing gears and parts communicating between the exterior and the cavity as well as two shafts on which the gears revolve. One face of the cavity is closed off by an apertured plate. The drive gear shaft extends through the aperture in the plate and supports the driven magnet. Drive means also extend through the aperture causing the hub of the driven magnet to turn the drive gear. All parts to the motor side of the plate may be standardized, while the pump body and its contents may be specially adapted to the particular ultimate installation of the pump.
