Abstract (en)
The pump according to the present invention consists of a piston (16) of which the end (17) is hollowed out and forms a chamber (19) having an opening (18) and an inlet valve (15). The alternative displacement of the piston draws and pushs the fluid back through the chamber (19). The system is totally "in line" and is suitable even for very abrasive fluids such as cement slurry. <IMAGE>
