CA 2687578

Apparatus and process for dispensing fluids, such as chemical concrete admixtures, using an air-operated pump and load cell for supporting and measuring at least substantially 100% of the weight of the pump and fluid dispensed through the pump. A double-action, dual piston design of the air- operated pump allows positive air pressure to be used during both fluid-filling and fluid-expelling phases.

L'invention concerne un appareil et un processus permettant de distribuer des fluides, tels que des adjuvants chimiques pour béton, en utilisant une pompe à air et une cellule de charge permettant de supporter et mesurer au moins pratiquement 100% du poids de la pompe et du fluide distribué par la pompe. Une configuration à double piston, double action de la pompe à air permet à une pression d'air positive d'être utilisée tant pendant la phase de remplissage de fluide que pendant la phase d'expulsion de fluide.
