  • Patent number: 9624925
    Abstract: The invention relates to a two-spindle screw pump of single-flow construction, comprising a pump housing, which has a pump portion, a bearing portion and a gear portion with a gear chamber, wherein the bearing portion and the pump portion are realized separately from each other characterized in that the gearwheel and the fastening element (and thus the shaft) are mutually rotatable, so that a spacing of the flanks of the feed screws (the flank clearance of the feed screws) is adjustable, that an opening is provided on the gear portion of the pump housing, that the opening is provided with a detachable cover, that the opening is arranged such that the cover is detachable in the mounted state of the screw pump, and that the gear chamber, for the adjustment of the flank clearance of the feed screws, can be reached with the tool necessary for this purpose.
