Abstract
A volume control for a multi-nozzle rotary pump filling system in which a plurality of rotary pumps are driven from a common drive. Each pump is connected with its own nozzle by way of a connection that includes a volume control operable to adjust the back pressure on the rotary pump to thereby vary the amount of product dispensed by the nozzle. In case of more viscous products, a by-pass line which includes a relief valve is also provided between the inlet side of the control unit and the in-feed side of the pump.
