A single flight screw, a single flight high pressure screw pump and the use of the pump in a compactor for compacting and dewatering debris commonly found in waste water. The bore, screw diameter and the flight spacing are constant and the compression force is mostly axial. The work is done at the very end of the screw. 1. A single flight screw , said screw comprising a shaft having two ends , said shaft having a single flight helical wrapped around said shaft in an inclined plane , essentially from one end of said shaft to the opposite end of said shaft , said single flight helical having a front end with a terminating end wherein said front end of said single flight helical , at said terminating end , is cut such that the vertical height of said flight is 30 to 70 percent of the height of said remainder of said helical flight.2. A single flight claim 1 , high pressure screw pump comprising a screw housing having a front opening and a hack and located within said screw housing claim 1 , a screw as claimed in .3. A single flight claim 2 , high pressure screw pump as claimed in claim 2 , wherein claim 2 , in addition claim 2 ,a. the screw housing is lined with intermittent linear supports;b. said screw housing having mounted thereon, at the front thereof, a spring housing, said spring housing having an open back end and an open front end;{'figref': {'@idref': 'DRAWINGS', 'FIG. 5'}, 'c. contained in said spring housing a resistant spring assembly as shown in .'}4. A single flight claim 2 , high pressure screw pump as claimed in claim 2 , wherein claim 2 , in addition claim 2 ,a. the screw housing is lined with intermittent linear supports;b. said screw housing having mounted thereon, at the front thereof, a spring housing, said spring housing having an open back end and an open front end;{'figref': {'@idref': 'DRAWINGS', 'FIG. 6'}, 'c. contained in said spring housing a resistant spring assembly as shown in .'}5. A single flight claim 2 , high pressure screw pump as ...
