ABSTRACT:
A strainer attachment for the inlet fitting of a submersible pump. A threaded rod carries two retainer elements, one of which is rigidly mounted on one end of the rod and the other of which is threaded onto the rod. With the rod held in a skewed position, the stationary retainer element can be passed through the inlet passage formed in the inlet fitting. When the rod is then oriented in alignment with the pump axis, the retainer elements span the inlet opening. When the movable retainer element is threaded toward the stationary element and against the inlet plate of the inlet fitting, the two retainer elements grip the inlet plate between them to secure the rod in place. A strainer body having mesh openings for straining the liquid that is being pumped can be threaded onto the rod.
