Abstract

1326342 Reciprocating pumps TAMAGAWA KIKAI KINZOKU KK 20 April 1971 [21 Sept 1970] 10155/71 Heading F1A In a liquid-piston pump for slurry, comprising a pumping chamber 11 with a liquid-piston 22 actuated by a piston 2, entry of gas bubbles into the pumping chamber from the slurry is prevented by injecting bubble-free slurry liquor through injection pipe 19 into the slurry 20 in chamber 11 in a direction away from the liquid-piston to carry the slurry bubbles towards valve box 4. A check valve 16 prevents back flow from pipe 19. Liquor pump 17 draws from reservoir 18. The liquor flow-rate may be automatically controlled by means detecting the concentration of gas in the slurry.
