Abstract
A gear pump having shafts mounted with rolling element bearings and having mechanical seals on the face of the gears provides improved “clean-in-place” ability. Preferably, washer-like seals are mounted on the face of the gears with a suitable adhesive and the cup-like seals are mounted in end housings. The end housings mate with a central housing enclosing the gears, to provide improved assembly.
