Abstract (en)
[origin: EP1043476A2] A device for pumping slurry, e.g. mud containing drill cuttings generated during drilling for oil or the like, comprises a generally horizontally disposed macerator having two counter-rotating shafts with alternating cutters and spacers above which is mounted a vertically orientated progressing cavity pump. The spaces in the macerator are axially thicker than the cutting discs so that the macerator will pass particles of a size acceptable to the pump. Impellors horizontally adjacent to the macerator are provided for agitating the slurry to be pumped. <IMAGE>
