Abstract: A multiple section, expandable external gear pump is disclosed that includes a single inlet in communication with each gear set without a manifold disposed external to the casing. The pump also includes a single outlet in communication with each gear set without an outlet manifold disposed external to the pump casing. The casing includes a head and an end casing/bracket section with one or more individual casing sections sandwiched therebetween. Each casing section accommodates its own drive gear/idler gear pair and each gear pair is in communication with a common inlet chamber and a common outlet chamber without any manifold structures disposed external to the pump casing. The end casing/bracket may also accommodate a gear pair.
