Abstract:
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.
