Abstract
Disclosed is a dual pump with priming reservoir assembly for dispensing a fluid chemical at a low flow rate into a substance with which the fluids is to be mixed. It includes adjacent primary and secondary piston-type pumps and a separation chamber or priming reservoir. The primary pump has a discharge capacity in substantial excess of the final dispensing fluid flow rate. The suction side of this pump is connected to a remote source of chemical fluid to be dispensed. The discharge line of the primary pump and the suction side of the secondary pump communicate with the reservoir. The discharge side of the secondary pump is connected to the dispensing line and its output is adjusted to provide the desired, accurately metered dispensing fluid flow.
