PUMP FOR THICK VISCOUS SLURRY Russian patent published in 2002 - IPC

Abstract RU 2180708 C1

FIELD: devices for transfer of non-homogeneous stiff stock, for example, concrete and slurry at low percentage of liquid phase which belongs to dehydrated mass. SUBSTANCE: proposed pump has housing with suction and discharge ports, swivel gates for opening and closing these ports and expulsion mechanism. Swivel gate is made in form of hollow cylinder with side port along its generatrix; it is mounted in bore found in housing. External surface of this gate is engageable with surface of bore. Expulsion mechanism is provided with plunger mounted coaxially relative to swivel gate for performing reciprocating motion inside it; suction port in housing is of the same position and shape as side port in swivel gate; length of each of them is adequate to stroke of expulsion mechanism plunger. EFFECT: reduced overall dimensions of pump; simplified construction. 3 dwg
