FRONT PULL-OUT HYDRAULICS FOR PUMPS

摘要

In one embodiment of the disclosure, a dish insert may be installed in a pump head such that the dish insert may be removed from the reagent head side of the pump head. Port holes permit movement of hydraulic fluid through the dish insert. The dish insert may be affixed to the pump head by fasteners. The dish insert may include removal means. For example, removal holes may be provided wherein fasteners nay be threaded until the fasteners "bottom out" on the pump head. In this way, fasteners may force the dish insert out of the mounted position by acting against the threads as a jack screw.
