Liquid pump assembly

Abstract

An assembly for a liquid pump having inlet and outlet ports at its front side and an electric motor mounted on its operating shaft at its back side includes a one piece housing, preferably molded of a plastic. The housing includes a substantially flat top wall, a U-shaped bottom wall having the ends of its arms integral with the sides of the top wall, and a back wall integral with and extending across one end of the top wall and bottom wall with the other end of the housing being open. A mounting plate is secured to the pump between the pump and the motor. The pump and motor assembly is mounted in the open end of the housing with the motor being within the housing and the mounting plate being seated against the open end of the housing. Bolts extend through openings in lugs projecting from the arms of the bottom plate and are threaded into holes in lugs on the sides of the mounting plate to secure the mounting plate to the housing. Alignment pins project from the housing fits into alignment notches in the sides of the mounting plate to align the holes in the lugs on the housing and mounting plate. Wires from the motor extend through a notch in the mounting plate and cooperate with the edges of the notch to prevent longitudinal movement of the wires and thus provide a strain relief.
