Abstract
A pump fitting has an inlet adaptor () for connection to an outlet () of a container () of fluid and including an inlet passage (), an outlet passage () for fluid and a pump housing () between the inlet passage () and the outlet passage (). The pump housing () contains a rotor () rotatably received in an interior surface of the housing (). The rotor () includes a housing-engaging surface () co-operating with the interior surface of the housing () to form a seal therebetween and also including at least one shaped surface () radially inwardly of the housing-engaging surface and forming with the interior surface of the housing a chamber () for conveying fluid from the inlet passage () to the outlet passage () on rotation of the rotor (). A seal () is provided between the outlet passage () and the inlet passage (), the seal () being urged into engagement with the rotor () to prevent fluid passing from the outlet passage () to the inlet passage () as the shaped surface rotates. The inlet passage (), the outlet passage () and the housing () are formed as a one-piece molding.
