Abstract: A rotary pump for a fluid metering system is provided. The rotary pump reciprocates, and is reversed by a signal from a limit switch that is deflected by an actuator arm on a rotating sleeve of the pump system. The sleeve receives a gasket that forms a seal between the sleeve and the housing, the gasket having an opening surrounding a side hole of the sleeve to permit fluid to pass through the side hole between a pump volume and an inlet port or outlet port of the housing.
