Abstract: The invented split gear mechanism replaces a standard single spur gear used within metering pumps and operates in conjunction with a similar driven split gear mechanism. The invention includes two or more layered gear pairs, each layer being re-indexed at a slightly altered fixed orientation relative to a given index point. The invention is typically used within "precision metering pumps" used, for example, in the textile industry. The invention facilitates uniformity by reducing pulsations generated by existing pumps. A method for reducing pulsations in pumping tasks is also included.
