Abstract
An external gear pump including seals, bearings, bushing/seal housings, choke collars and shafts that are all removable for maintenance and/or replacement without removing either endplate or internals from the case assembly. The preferred pump includes four bearing caps that can be removed without removing the pump from its mounted position. By removing the four bearing caps, access is gained inside the pump housing to all of the seals, bearings, bushing/seal housings, choke collars and most importantly, the drive and idler shafts within the pump housing. Further, the two shafts can be slipped out of the pump without disturbing the internal parts and endplates. This capability facilitates maintenance and replacement of major components without removing the pump from its mounted position.
